Shades of Water

Originally published on Tangible Virtual Water on 04/12/2016.

Water is available on Earth in various forms and sources: oceans, lakes, rivers and streams, snow, glaciers, precipitation, fog, wetlands, underground aquifers…

This post is an opportunity to investigate a little, and clarify the terminology which categorises different types of water and virtual water, to understand how they are affected from human use.

Part of the range of terms attributed to water are divided in colours which somewhat reflect the state of the water in question and are typically attributed to different sources, kinds and uses.

These are: blue, green, grey and black water.


Blue water

Rockström et al. refer to blue water as liquid water in rivers and aquifers, in addition to groundwater, as considered by Hoekstra et al., and lakes and dams, according to Falkenmark et al.


Green Water

Rockström et al. explain green water is “naturally infiltrated rain, attached to soil particles and accessible to roots”.

Blue and green water are closely linked in two ways, mainly: the moisture present in the soil percolates restoring the underlying aquifer, and blue water can be used to supply the lack of green water through irrigation (Rockström et al.)

There are two water complementary flows: the blue water flow through rivers, wetlands and underlying aquifers or groundwater and the green vapour water.

The green water flow is from natural systems (crops, forests…), it evaporates back into the atmosphere and comes back in form of precipitation.

The cycle can then start again.


Grey Water

Jefferson et al. define grey water as arising “from domestic washing operations. As such sources include waste from hand basins, kitchen sinks and washing machines, but specifically exclude foul or black water sources (toilet, bidets and urinals).” […] usually generated by the use of soap or soap products for body washing and as such, varies in quality according to, amongst other things, geographical location, demographics and level of occupancy.”

Grey water is collected from sinks, showers, baths, washing machines, dishwashers and can be distributed with different means, such as distribution of water directly from the sink into the toilet as flushing water, or by treating it and making it suitable for irrigation.

In addition, grey water as its own footprint, which the water footprint website defines as “The volume of freshwater that is required to assimilate the load of pollutants based on natural background concentrations and existing ambient water quality standards. It is calculated as the volume of water that is required to dilute pollutants to such an extent that the quality of the water remains above agreed water quality standards.”

Black Water

Black water is water which has come into contact with fecal matter, which contains harmful bacteria and pathogens.
Unlike grey water, coming into contact with this type of waste means that the water is not able to be reused, for example in irrigation, without the risk of contamination.

Waste water has its quality affected due to human use, from domestic use (grey and black water) to industrial or commercial production.

As mentioned before, we are living within the context of  a water crisis: using as little water and as efficiently as possible is vital.

Water-efficient solutions are available and at times in place.

The image below is an example of a greenhouse village which shows the potential of what can be achieved already.
It is decentralised from an energy and water supply and with a waste and water treatment. This means it is an independent, closed loop system where there is no waste or entropy: everything is a valuable input.

Water is supplied by collecting rain water and is kept in a cycle by treating grey water from the home, which is used for irrigating the greenhouse, itself is a source of energy; black water waste gets treated too and provides soil conditioner.

This introduction to different types of water will be useful when I delve into the cost of meat, in my upcoming post.

In the meantime, more information on types of water, water footprint, virtual water and more and can be found from the water footprint website.

What’s in Your Toothpaste? Different Types of Animal-Free Toothpaste

What’s in your toothpaste?

Ever since starting to eat vegan food, I’ve been on a learning curve of progressive knowledge absorption, finding out so many products I din’t consider to have any animal ingredients, in fact, may have (sweets, alcohol…).

Except from food, I have also been choosing health&beauty products that are vegan, such as face creams, deodorants, body lotions, shower gels, soaps and toothpaste.

OLIO – the app that helps avoid food waste

So much food, which takes so much energy, work and care to be made, gets wasted every single day…bag loads of edible food are discarded merely yards away from people who cannot even afford to buy it. It breaks my heart.
It’s a symptom of a failed food system, and even though it may be the norm in the Global North it does not mean it’s right.

This video says it all: The Extraordinary Life and Times of a Strawberry. It’s under 2 minutes and well worth a watch.

The good news is, we can all do something to prevent this is awful waste.
During class, one day, someone mentioned there was an app which helps reduce food waste by connecting people who have surplus / unwanted / unnecessary food to others who want or need it.

100 Ways to be More Sustainable – 100th Post

Hello everyone, this is my 100th post! 🙂

I started this blog on 5th February 2012, over 2 years ago, and have finally got to the 100 mark.

As I started off with the idea of writing a blog that would show that acting more sustainably can be easy and have benefits such as saving energy, money and pollute less, I thought it would be a good idea to write about 100 ways to be more sustainable for the 100th post 🙂


First, though, I would like to thank you.

Thank you if you are reading this, thank you if you have been following me since the start, since last year or if you are a new follower.

Thank you for every “like”, comment and share. Thank you for supporting me in my little mission.


Now, to the more practical side of things.

Everything we do has an impact on the environment, this impact can be more or less sustainable, if we think of it as “capable of being maintained as a steady level without exhausting natural resources or causing severe ecological damage”.

So, here we go, just over 100 tips on how to be more sustainable! Click on the links to discover more about these eco-tactics 🙂


Less energy-hungry food (16)

  • Eat less energy-demanding meat. It only takes a few seconds to look at this World Food Clock and realise how we produce, consume and waste every single second. (Thank you for sharing, Janina). Here are some ideas to get your newly recommended 7 (or even more) a day! 10 Ways to 10 a Day from KHGS.
  • Eat more lentils! They are an excellent sustainable source of protein and easy to grow too.

  • Store food properly. By doing so, it will last longer and you will waste less. Did you know spring onions last longer in a glass of water in the fridge? 🙂
  • Plan meals ahead and let frozen meals thaw in the fridge. This will save you energy because the fridge will need less electricity to keep the temperature low, plus you won’t need to defrost the meal in the microwave either. Guide: How to defrost safely.
  • Buy locally, go to farmers’ markets or local farms – you will be supporting smaller producers and you can save money too.
  • Have a look at supermarkets’ reduced to clear sections.
    You can find amazing bargains, especially towards the end of the day (loaves of bread for 20p), and purchase food that would otherwise go to waste. You can then consume it as soon as possible or freeze it for future use and save a lot of money.


Reduced Food

Amazingly cheap but still perfectly fine reduced food


  • Understand the difference between “best before” dates and “use by” dates. Look at the Ultimate Shelf Life Guide to avoid wasting food unnecessarily.
  • When you go out, try local produce and products. From craft beers to wine, from pies to vegetables and fruit: give your local producers a try!


Less Pollution (22)

  • Try natural alternative to laundry detergents, such as affordable soap nuts.

Green People Mascara

  • Give car sharing a try. Try sharing rides with colleagues, share a taxi or simply use public transport or start cycling.
  • Learn to drive consuming less fuel: Cut your speed and petrol bill.
    As a pedestrian, if you see a single car coming along, and you’re not in too much of a rush of course, let it drive past so they don’t need to break and re-depart after, which would use more fuel.
  • Walk more. Ramblers is a website that shows many walking routes, or you could simply walk more and use your car less.
  • If you need to pack a parcel, reuse bubble wrap or – even better – use strips of waste paper and ask the receiver to reuse or recycle them after.
  • Try purchasing less plastic and buying reusable items made of less toxic materials. You can start by taking a reusable bag when you go shopping. Life Without Plastic.
  • When you are eating out, ask for tap water rather than bottled water (in areas where it is safe, of course). Why Tap Water is Better.
  • To freshen your home, use essential oils rather than chemical-filled air fresheners. You only need a few drops in a burner or in a spray bottle.
  • Instead of sponges which are not recyclable and harbour bacteria, use cloths which can be washed and reused.


Reusable Material Cloth and Ecover

  • Switch to online billing rather than paper billing, some companies offer discounts for the switch too.
  • To get rid of oil stains, rub chalk on the affected area before washing rather than using harsh chemicals.
  • Take your own lunch to work, you will cut down on a lot of packaging and also save around £1,000 per year!

  • When changing the oil for your car, make sure you dispose of it properly as it can pollute waterways and kill wildlife. Find your nearest UK oil bank.
  • Try to purchase products that don’t rely on batteries, and if they must, use rechargeable ones. Look for solar power chargers for an extra sustainable option.


Make, repair&fix (12)


Make Do and Mend



  • Turn used trousers into shorts or skirts.
  • Get to know your neighbours, they may need something you can offer and they may be able to offer something you need.
    My flatmate designed the website for the restaurant next door to us.
  • Make your own body scrub, for example by mixing olive oil with a bit of ground salt and sugar. Simple!
  • Make your mirrors, windows and glass objects sparkle by using white vinegar. Add some in a spray bottle (you can dilute it with 1:10 vinegar to water up to 50/50) and apply with scrunched newspaper to leave no traces or marks.
  • Make a wood cleaner by mixing two parts of vegetable oil with one part lemon juice, use with a cloth.
  • If you prefer purchasing cleaning products, choose eco-friendly ones such as Ecover.
  • To freshen up smelly shoes, try filling them up with scrunched newspaper overnight or sprinkle the insides with bicarbonate of soda or talcum powder and shake them out the day after.


Buy less, use less and buy better quality (9)


  • Do a little research about brands you may want to purchase: do they pay sustainable wages to their workers? Labour Behind the Label.
  • Use less plastic and more natural or oil-free materials, have a look at alternatives from Life Without Plastic.
  • Reuse things: for example, jars can be used as containers for more food or other objects.
    Here are 40 ways to reuse newspaper. Take a reusable coffee cup, like a Keep Cup, to the coffee shop instead of using disposable ones. Some places give you a discount if you bring your own cup too!
  • Buy second-hand books, they can be so much cheaper! Or borrow reading material from your local library.
  • Have your shoes resoled once they need to and keep on using them. I have had my boots for 7 years and they’re great!
  • Dye clothes that have faded and give them a new life.


Bank Better


  • Triodos Bank is “a global pioneer of sustainable banking.” Their mission is “to make money work for positive social, environmental and cultural change.”




  • Give someone the opportunity to create a sustainable business and alleviate poverty with the Kiva project, you can lend as little as $25 to someone who needs it and who will give it back to you when possible.


Save Energy (15)


  • Invest in an energy-saving product such as Energenie in order to save energy and money.
  • When charging devices, unplug them once they are fully charged, avoid leaving them plugged in unnecessarily or overnight.
  • Look for energy-efficient domestic appliances.
  • Buy rechargeable batteries and replace your batteries rather than replacing your whole phone.
  • Turn off the oven a few minutes before the time is up, the heat remains in the oven for a long time after you switch it off.
  • Try to use the oven as its full capacity when you use it, you can add meals to eat later in the week or use it to make croutons out of stale bread, for example.
  • Switch to a green energy supplier.
  • Wear warmer clothing and adjust your central heating to avoid wasting energy and money.
  • When you dry your clothes indoors, avoid putting them on radiators as this will stop the heat from reaching the room, create damp and good conditions for mold to grow.
  • Cook in bulk and therefore save energy. You can freeze additional portions.
  • Cook food in a steamer, you can cook different things on each level at the same time.


Recycle and Reuse (11)


  • Save paint from going to waste, Community Repaint collect reusable paint and distribute it to those who need it, helping them and avoiding waste.
  • Recycle your shoes at a collection bank.
  • Clear your cupboards of old electronic equipment, sell it or recycle in appropriate centres.
  • Consider going to charity shops first to find what you need. It could be a frame, and even if you don’t like a picture you may love the frame. Give things a new life.
  • You can recycle all sorts of things, even ink cartridges. Check before you throw.
  • Donate, don’t throw. If you have unwanted furniture, give it to a friend or donate it to a charity.
  • Borrow instead of buying, can help you find what you need with no need to buy it.
  • Share more. You will save money, use fewer resources, meet new people… 10 reasons to share.
  • Use carpets in many ways to avoid them ending up in landfill. Use them to line cupboards, cars as mats, pet beds,  as doormats and even under plant pots.


Waste Less (9)


  • Compost food and tea bags to fertilise the soil which you will be able to use to grow your own herbs, vegetables, food or plants.
  • Reuse timber material from skips.
  • Take your own suit bags to the dry cleaner’s rather than having them give you flimsy plastic ones and take back the hangers for them to reuse.
  • Reuse tea bags – when you make tea in a cup, you can often reuse it for another cup as their strength is usually enough for a few cups. Or use loose tea leaves and then compost them if possible.

CHai Tea

  • Buy in bulk or buy refills.
  • When you go to a restaurant, if you cannot finish your meal, ask to take it away in a doggy box. It’s a compliment to those who took care to source and prepare the food, and you have paid for the whole portion, don’t be shy! Too Good To Waste Campaign.


Save Water (5)


  • Choose a dual flush system or put a water-saving device in your loo tank to use less water with every flush.
  • When you are waiting for cold water to turn hot, collect it rather than letting it go down the drain and use it to water flower and plants, wash fruit and vegetables, fill the kettle…don’t waste it!
  • Use a tank to collect rain water. It’s ideal to water plants or wash the car.
  • Wash your vegetables in a bowl rather than under running water and use that water for plants and flowers.

How to Sell on eBay – Be Sustainable, Make and Save Money

Do you own anything that you do don’t use or need? Make money and be sustainable, sell it on eBay! 🙂

eBay is a brilliant, easy and sustainable way of disposing of things you no longer need or use and make money and also to purchase new or used things that others no longer need or want at affordable prices.

It encourages to make the most of something and using what’s already there rather that letting it gather dust and take up space or buying more new things from. I love how it simply connects the demand and supply of an item so cleverly.

I have bought many things on eBay such as lovely dresses, our table and chairs and our coffee table.

If one of your new year’s resolutions is to de-clutter your home or make some extra money, get selling! 🙂

I became a member in November 2009 at a time when I really needed money and could not find a part-time job while studying and have occasionally sold (and bought!) items on eBay ever since.

I have gained experience on how to successfully sell and send items efficiently and have a few useful tips for you that I’d like to share. I have embedded many useful links so simply click on the keywords to go to their web pages.

Please note these tips are all gathered from my personal experience as an occasional seller and buyer, there are different rules for business sellers and you may be able to change some settings to suit your particular needs, so please use my tips as guidance and refer to the exhaustive information on for unequivocal facts.


So, to get started:

  1. Register on eBay

I remember it was really straight forward, I just followed the directions from the site.


2. Create a Paypal account

If you haven’t already got one, create a Paypal account. Paypal is a “safe, fast and easy” way to make and receive payments online and you will be able to use it on many other sites to pay and receive money securely.

The fees eBay takes off my sales are automatically deducted from my Paypal account, I think this is the default method, so after logging onto your Paypal account you will be able to see how much the buyer pays for each item you sell and how much is deducted from it to go to eBay.

They actually withdraw the fee from your Paypal account 10 days after sending you a monthly invoice that you will receive on both you e-mail and on ebay in the “Messages” section.

From time to time Paypal make minor changes to their user agreement policy, when they do so they send an e-mail where you can easily follow the link showing the changes so you can always be up to date with everything.


3. Create an eBay folder in your e-mail account

I  find it very useful to keep track of important e-mails and also to store the receipts of payments from buyers or receipts of payments I make for any future reference.


4. Buy your P&P essential kit

Avoid buying expensive P&P equipment from places such as the Post Office or WHSmith, their prices are seriously inflated. If possible go somewhere such as Poundland or perhaps a more affordable stationery shop or to a supermarket to buy reasonably priced brown wrapping paper, sellotape, and different sized envelopes.

If you need bubble wrap to pad something fragile, there’s no need to buy some: simply go to any shop that sells items which might be transported in bubble wrap (a supermarket’s crockery department, a shop that sells vases, frames or glasses etc.), and ask a member of staff if you could have some of their bubble wrap. All they do is (hopefully) recycle it so there shouldn’t be any problems. I have bags full of bubble wrap and didn’t spend a penny on any of it!

eBay Essential Selling Kit

eBay Essential Selling Kit

-Thin paper: got it for free from shops or kept it from previous padded items ready to reuse

-Sellotape: strong, thick one from Poundland, very efficient

-Scissors: when using brown paper!

-Normal pen: for writing addresses on small size packets

-Big felt tip pen: for writing addresses on bigger items or boxes

-Pre-made padded envelopes: they are more expensive but they save time and hassle, if you receive items in them you can often reuse them by covering the old address with a piece of paper with the new address on it

-Brown paper: cheapest way to wrap items, from Poundland

-Bubble wrap: got it for free from shops or kept it from previous padded items ready to reuse

-“Postage made easy” leaflet: got it from the Post Office to have an idea of postage charges, nationally and internationally


5. Gather the items you’d like to sell

  • The items that are easier to sell are those that stand out for something: the brand, the popularity of the item, the colour/print etc.

It will be hard to sell a really plain grey T-shirt as most people input brand names or certain characteristics in the search box. On the other hand, if it has sequins or it’s ’80s style or it’s of a certain brand it will come up on more searches and will be viewed by more potential buyers.

  • If you have a few items to sell, save time by taking good, clear pictures of them all at once. If possible choose a place where the items can be seen with a natural light. Have a look at how other people take their pictures and suss how you’d like to see something before buying it, the more pictures the better.
  •  There are 2 main selling methods, “Quick Sell”  allows 4 pictures (1 or 4 pictures can be uploaded for free according to what it is, clothing has 4 free pictures available); the “Advanced Sell”  method offers more detailed listing options and you can upload 12 pictures for clothing and other items. Many people who sell designer items prefer this options as it can really showcase a piece properly.
  • Check each item carefully and look for any faults. To avoid any problems after the sale, make sure you list and describe if the item has any particular fault, a stain on a top, a chip or scuff…the buyers have to know what to expect to avoid risking any sort of complaint. If something is used buyers know if won’t be exactly how it’d be straight off the shelf, however if there is a particular fault let them know and take a picture of it to avoid any misunderstandings.
  • Title and describe the items properly: you have an 80-character allowance for your item’s title so use it! I sometimes see items listed as “red jumper” and nothing else. Describe it more to appear on more relevant searches, for example: “Topshop Red V Neck Cotton Jumper with Pockets Size Medium Great Condition”. Describe it well in the description window too, write about the material, its condition, whether it’s machine washable, if there are any faults, what season it’s best for, even suggestions on what occasions to wear it if you want. It will save you time to add as much information as possible since the beginning rather than having to answer buyers’ questions such as “What is it made of?”.
  • If you are selling an item but not sending it, therefore selecting the “Collection in person only” make sure to include this in the item description too in order to avoid misunderstandings.
  • If you would like to sell something with a starting price higher than 99p, it’s better to wait the special “Free Insertion Fee Weekend” so once the item sells, you don’t have to pay them.
  • If you want to sell something valuable at a certain price you can also select a “reserve” of minimum £50 to ensure the item will not sell unless the final price is above your reserve price.
  • If you would like to sell something that buyers can buy straight away, without the need to wait for the end of the auction, select the “Buy it now” option for a small fee.

Start selling!

  • There may be times when a certain buyer will ask you to end the auction early or if you can send the item through a different postage method to the ones you have listed etc. Such requests are usually extremely straight forward and easy to handle, and eBay’s site is full of helpful articles to help you with anything at any time.
  • Be sure to be around once the auction ends as you’ll have to dispatch the items as soon as possible, make sure you are not on holiday!
  • Pack things carefully, especially if using brown paper as it can tear more easily than some pre-made padded envelopes,  and write the address very clearly to avoid delaying the delivery of the item. I usually write “From: (my address)” in case there are any problems and the item has to come back to me (hasn’t happened yet though).

Additional information and links:


I hope these tips are useful and will show you how easy it can be to part with something you don’t need (rather than waste it) so someone else can use it and make money too!

Are you planning to do so?

D.I.Y. Upcycling

Upcycling is converting waste materials or useless things into something new and better than what they were before.

It’s extremely sustainable to upcycle as it skips the energy needs and efforts required to recycle and of course it still keeps materials away from landfill by giving them a new life.

I just love the fact that with a little imagination you can turn something unwanted and discarded into a unique masterpiece.

Just think of the very basic properties of things around you: jars can hold jam just as they can hold buttons or paper clips, a piece of material can cover something or cat be sewn into something else, cut up…

I’m really not that good at building things or arts and crafts but I managed to upcycle 2 things recently:

Lime pickle Jar

Up to a few weeks ago I kept my cotton wool in the plastic bag it comes in from the shop, hanging in the bathroom. Not a great sight. So I was wondering how I could keep some cotton wool in the bathroom without that plastic eyesore.

I love lime pickle and the Sharwood’s brand one comes in a really lovely shaped jar. I decided to wash it and reuse it.

I had some old nail varnish that had gone a bit gloopy and was no longer suitable for painting my nails so I painted the jar’s lid with it. Here is the result!

Upcycling a lime pickle jar into a cotton wool holder

Definitely nicer than a plastic bag! It’s very simple and I like it 🙂

The second object I upcycled was my electronic dictionary box. When I bought it in China I thought this sturdy box would be great to reuse, I therefore shipped it back to the U.K. together with other China goodies and, after 3 years, I finally carried out my plan and covered it with some really beautiful thick wrapping paper.

Box and wrapping paper

The wrapping paper came from a birthday present my boyfriend gave me so that too was upcycled.

Upcycled colourful box

Now I just need to think what to put in it.

Cheese grater? Pencil holder!

Isn’t this a cool idea? This picture comes from a very interesting article on the innovation diaries about how upcycling is actually better than recycling.

The Energy Used in Your Home

We all need and use energy, but do we realise how much we use?

Take home heating: anyone who deals with the bills knows how dear it is to warm your house.

But how much of the world’s use of energy is used for generating heat?

Do you think it’s 27%, 37%, 47% or 57%?

It’s 47%! Far higher than transportation, which accounts for 27%.

Test yourself more with the National Geographic Home Heating Quiz.

If you want to save energy, reduce your carbon footprint and save money, have a look at National Geographic’s 360º Energy Diet.

You can save energy by cutting down on:

What you buy and consume

Use less water, gas and electricity, buy more organic products, borrow something instead of buying it new…


Reduce consumption of resource-intensive meat, eat sustainable fish, eat less processed food…


If you need to drive, get rid of unnecessary weight from your car and drive at an even speed to consume less fuel, use public transport whenever you can, invest in a fuel-efficient car…

At home

Lower your thermostat by 2ºC, or increase it during the summer, use energy-saving light bulbs, hang your clothes instead of using a dryer (your clothes will last longer too!)

Water use

Give up bottled water for tap water -use filters or Brita taps for extra pure water-, turn off the tap while brushing your teeth and scrubbing dishes, have shorter showers -even 1 minute less in the shower can save a lot!-, use a low-flow shower head, collect water for the garden using a rain barrel…

Waste disposal and reduction

Keep RRR in mind: Reduce, Reuse and Recycle!

Sending less things to landfill means fewer resources will be used to manage and transport all of it. Recycle all glass, paper, plastic aluminium, batteries and anything else, change to paperless billing, use material or long-lasting reusable bags for your shopping, compost at home, recycle or donate unwanted shoes, clothes, computers and phones and only buy what you really need.

I read a really interesting article on the 10:10 site, the organisation that focuses on cutting carbon emissions 10% at a time and that I previously wrote about regarding their Lighter Later campaign, about a family who got rid of their car in 2010.

10:10 picture from

Check how they became healthier, shopped more locally and saved a lot of money on the Giving Up The Car case study page.

Also  have a look at the Household Energy Saving Booklet for more energy and money-saving tips. It’s incredible how much heating energy is lost through poor insulation.

If you are renting a home, there are useful tips for tenants and landlords on the booklet too.

More links to look at:

Berti Investments, A business programme supported by Dragon’s Den’s James Caan which helps UK low-carbon businesses

Energy Bill Revolution Turn carbon taxes into funds to make homes super-energy efficient by signing this petition, what an investment!

Tune up your boiler, save 30% energy

Another great site I would like to recommend if you would like to save energy and money and see evident results in a year is a site that my journalist friend, The New Journalist blogger, told me about.

GGT: Going Green today.

Sign up, it only takes a few minutes to complete the initial questionnaire to determine how much energy is used in your home, what kind of light bulbs you use, what devices you use to listen to music, how much you travel, how often you cook at home, how much meat you consume , what sort of water heater you use… when it asks you about your furnace’s filter, it means your central heating system’s boiler (this site is American and I had to look it up as I wasn’t even aware I had a furnace 🙂 )

At the end of the survey you can choose to receive “Green Reminders” posted on your Facebook wall to ease your way into being greener day by day.

You also get a report with the number of steps you could take in a year to be greener. With 58 free steps I could save $5,304 in a year! Great!

It’s also good to see some companies, such as British Gas and their energy App, are making easier for us to monitor our day-to-day energy use.

Whatever you do in life, there’s always a green, sustainable way of doing it.
