A significant percentage of UK household waste is waste food.
Now it is true that better planning, better reuse can greatly reduce this. However only food that is uncooked can be put in a compost heap. The UK produces about 5 million tonnes of food waste year. If this was collected it could reduce emissions dramatically, as well as potentially creating significant biogas for power generation.

If this is the case, why is so much of our recycling simply being burned?
Continue reading “The UK sorts our rubbish at higher rates than anywhere else in the world, so why is so much being incinerated”Humans eat between 1-2kg of food per day, so each person consumes roughly 1.2 tonnes a year. That means that one billion tonnes of food could feed half of China or India or alternatively the next 3 biggest countries – the USA Indonesia and Pakistan.
Another way of thinking about it, is that if humanity ceased wasting food tomorrow, there would be enough to feed the whole planet completely.

The industry as obviously attacked this, in part by pointing out the rules demanding that all cars be practically clear of emissions by 2025 will rule out clean fuels such as liquid hydrogen.

There is no requirement as to how long technology is required to last. In the past, that has perhaps been less noticeable, as the advance in the capabilities has been so fast, that an upgrade generally became desired long before the product wore out.
However, there has been an alarming trend which has seen manufacturers removing manuals to allow products to be serviced, and or sealing parts of the product, so that batteries cannot be replaced or in some other way making DIY fixing hard or impossible.

What normally happens, is that once the water has been fully treated, it is returned to the river. The problem with this, is that the water is at a higher temperature than the river, and this is not good for its ecosystem.

The idea of these small hydropower systems, is that we could build many of these tiny dams for far less than just a few large ones. More importantly, it would come with far less negative issues to those that come with historic large dams (for instance the proposed dam which threatens the future of 8th great ape species the Tapulani Orangutan).

The intention of this agreement is to stem the flow of extinctions that human activity has been causing for the last few centuries.
The hope is that this agreement can form the basis of a larger agreement at the UN, building on the early commitments from nations such as Nigeria Pakistan Costa Rica Canada and many more.

In many parts of the country, the number of deer are controlled by regular culls. However, during the pandemic these have not happened, and that now means that 2 culls in a row have been missed.
