08/04/13 - 19 MW Waste to Energy Plant Fuelled by Fats from London's Sewers Thames Water say that leftover, low-grade cooking oil and food fat will be collected from food outlets and manufacturers and solidified grease will be harvested from 'fat traps' in restaurants and from pinch-points around the capital's sewer network.

Sewers are designed to carry water, toilet tissue and human waste. . . but people pour lots of things down their kitchen sinks and also down the loo - this results in various problems from blocked drains to water pollution. Thames Water are asking us to remember this and to change our ways, see their Bin it - don't block it campaign. They clear around 55,000 blockages from our sewers each year at a cost of £12m and 7,000 customers suffer from sewage flooding into their homes and gardens – a truly miserable experience.
- Love your loo: Make sure that only wastewater, toilet tissue and human waste goes down your drains and into the sewer.
- Bin it - don't block it: Wrap up sanitary products, nappies, wet wipes and condoms and put them in the bin.
- Think - not in the sink! After cooking, fat, oil and grease should be left to cool - it can then be put in the bin or mixed with seeds and nuts to make a feeder for birds.
- Chemicals, solvents, and engine oil should be taken to your local refuse site.
- Paint (If you have small quantities, open the lid, allow the paint to harden, seal the pot tightly with the lid and put in your light grey rubbish bin or take to a county waste / recycling centre. Alternatively, a number of schemes use leftover paint. Visit www.communityrepaint.org.uk or call 0113 2003959. Alternatively contact the Orinoco Scrapstore, Oxford visit www.oxorinoco.org or call 01865 761113, or bring it along to the next Bring & Take in Charlbury.)
- Medicines, tablets, syringes and needles should be taken to your pharmacist, local hospital or health authority for safe disposal.
To flush, or not to flush?
Despite claims on products saying they are 'flushable', the only product to pass water industry 'flushability' tests so far is toilet paper! Manufacturers have their own tests, which are more lenient resulting in a greater number of products being labelled 'flushable'. Although they disappear when you flush your loo, they don't break down in the sewers - they would take several years to disintegrate. Bin it - don't block it leaflet
A quarter of our food waste goes down the sink!
In UK households, we throw 1.9m tonnes of liquid food, drinks and alcohol down our kitchen sinks - that's more than a quarter of the 7.2m tonnes total edible food that's thrown out. WRAP report 2012
- Do not pour oil down the sink or into the toilet, WODC will collect waste cooking oil or fat as part of the Food Waste Collection. Allow the oil or fat to cool - small amounts can be put in your food waste bin, large amounts should be put in a lidded, plastic bottle, such as an old drinks bottle, and either left in, or next to your food waste bin. (Cooking oil left in a glass container will not be collected)
- Do not pour smoothies or yoghurts down the sink or into the toilet, pour them into your food waste caddy for collection by WODC.
