Recycling organic waste into compost

The Department of Trade and Industry (DTI) in the early 1990’s launched an initiative to recycle domestic and industrial waste as compost for local farms. The Land Network was pioneering the use of recycled domestic and industrial waste as compost. This could have been a hugely popular and effective scheme, but due to the complex and weighty regulations, the uptake has been minimal. Instead of the projected 3,000 farms using the system, only 16 farms managed to get past the red tape and use the scheme last year. The point of the scheme was to use the 100 million tonnes of organic waste we produce each year to make compost for Britain’s farms. It was hoped that this would reduce the £1 billion a year spent on importing chemical fertilizers into the country. £1 billion adds up to a huge amount of chemical fertilizer, which in turn amounts to a massive amount of toxic chemicals introduced into the environment.

The scheme has many benefits. Local authorities can save the money that would be spent on dealing with the organic waste, the farmers save money because they do not have to pay out for fertilizers and the food grown with organic compost is more nutritionally beneficial. Reducing the use of chemical fertilizers helps the environment, because they leach toxic nitrates into the soil and pollute rivers and water supplies, and the transport of fertilizers across the world creates CO2 emissions. All in all this was a terrific idea that needs a little work to make it accessible to Britain’s farmers.

Reducing farm animals methane production

The easiest way to reduce climate change gases in the atmosphere is for all humans to become vegan. That is pretty much a very simple and painless way to reduce global warming gases. Obviously this is not going to happen, so scientists are working on ways to make cows and sheep produce less methane. Did you know that a quarter of all the methane produced by human activity comes from farm animals?

There are differing approaches to this problem around the world. In Germany for example, scientists at Hohenheim University have developed a plant-based pill that is combined with a special diet to reduce the methane cows produce by converting it to glucose. In New Zealand and the UK, the approach taken is to get farmers to grow different types of grass that have high levels of sugar. This diet of sugar rich grass changes the way bacteria in the animals’ stomachs break down plant material into waste gas. The problem with this type of grass is that it is more difficult to grow, so scientists are trying to make a genetically modified version which is hoped will be easier to grow. Which in effect is getting GM crops into the food chain through the back door.

The obvious answer to this particular methane gas problem is for people to stop eating meat and dairy products. The complex and expensive answer is to change the animals diet with pills and GM feed. Guess which one is more likely to happen?
