Day 5 – Foody Friday
As the weekend is nearly here many of us will be planning our
weekly shop, or making plans to eat with friends and family. According
to WRAP, the Waste and Resources Action Programme, approximately one
third of all the food produced in the world is lost or wasted.
In the UK this is valued at over £20bn worth of food waste
annually, or £810 worth of food thrown away on average by each family
in the UK per year.
We collect food waste from the full service catering restaurants
on the DWP estate. This goes to Anerobic Digestion (AD), a process for
recycling organic matter where bacteria break down food and convert it
to biogas, to be used as a renewable heat/electricity source. What’s
left over is heated to kill any unwanted bugs and used as a
nutrient-rich fertiliser. AD is becoming increasingly available for
household food waste collections too. As part of the AD process, the
waste is pre-treated and anything that looks like packaging is
removed. This includes any “compostable” packaging, vegware and coffee
cups. Although these are marketed as compostable, they need to go
through a very specific process in order to be composted. AD is not
appropriate for these items, and it’s not guaranteed that the AD plant
will go on to compost that waste – it could be incinerated or
landfilled (see yesterday’s email).
We currently don’t provide separate collections for “compostable”
packaging waste, so we ask that these items are placed in the General
If food or compostable packaging ends up in landfill –and there
is a good chance it will if you’re in an area of the UK where general
waste isn’t able to be incinerated – it produces landfill gas as it
degrades. Landfill gas is mostly made up of methane and carbon
dioxide, produced by micro-organisms as they break down our buried
waste. Both are powerful “greenhouse gases” which is one of the
reasons why landfill is considered so bad for the environment. Some
landfill sites are able to capture some of their landfill gas and
convert it to gas which can be escorted to the grid, but the tell-tale
odour of degrading waste reminds us that some of the gas is escaping
to the atmosphere and contributing to global warming.
What can I
do about this? It is thought that by cutting food waste the average UK
household could save £540 a year!
Plan your meals so that you only buy what you need.
“multibuy” offers on fresh food unless you know you will use it.
Store food properly – there are guides online about what should go in
different parts of your fridge and freezer.
Check your fridge
temperature is below 5ºc. Lots of items can perish quickly if it’s not
Veg that’s a bit wrinkled or wilted can be livened
up in a bowl of cold water.
There are loads of ways to use fruit
and veg without having to peel it; apple crumble with the skin on,
“crushed” potatoes instead of mash, scrub carrots and parsnips
clean instead of peeling them – it saves time too!
