Ad plants , you can’t make it up

Local plant produced too much gas and having to burn it off even thou there’s a shortage

Is it that it's producing too much or that it isn't of the correct quality to feed into the grid?
A gas to grid AD plant that I know of has to add propane to it to feed it into the grid. Sometimes (or more often occasionally) they flare it off if it isn't up to scratch.

Was told he was over producing so had to burn off the excess

ONLY in the UK would you have AD plants & be able to call them “green” or “environmental” 🤦‍♂️
Anywhere else they’d be a disaster . . .
The idea is quite ludicrous, but its not just in the UK, there's plenty more in other parts of Western Europe. It all dates back around 20 years when in order to meet "green" targets Govt's were throwing money at all forms of renewable energy, some were efficient. some were hopelessly inefficient. One of the most notorious was a biomass heating grant in Northern Ireland that was so generous it paid more than the entire cost of fuel. As a result buildings were opening their windows to let heat out in order to keep the boilers running.

That one did bring about the downfall of a government though...

Wind your neck in.

AD as a process is a great way of turning unwanted biomass (waste food, dead animals, sewerage, muck, slurry) into usable heat and energy, as @sjt01's setup admirably demonstrates. The economics and regulation are often all to cock and give undesirable outcomes (like growing crops and hauling digestate for miles).

This is by no means a situation exclusive to the UK.

I'm not sure what your problem is with the UK Roy. When I joined the forum a few years ago I really appreciated and valued your input - and challenge - from a very different environment and culture. More and more nowadays I feel like you just come here to insult my nation as a primary objective (rather than merely as a byproduct of constructively challenging our accepted norms). I lament the change in tone.

Nothing wrong with AD plants utilising food/ag waste to create a usable energy source.

Subsidising it, makes it inefficient
There's a good set up by Ross on Wye that does just that...all waste products.
There are others in Hfd that travel miles and miles carting maize etc and drive through Hfd as though they are the only ones on the road ......

Petition: Temporary Ban on agricultural use of sewage cake

In order to protect our land, we’re seeking a temporary ban of the agricultural use of sewage cake until better testing and treatment of waste can be proven. We call on all farmers after this harvest to refuse to accept any more until things change.

Some research suggests that the contamination of land is far more serious than just heavy metal build ups. There is an increasing amount of micro plastics and forever chemicals appearing in sewage cake. We think testing for these when it leaves the processing plants isn’t adequate, and that processing needs to adapt to be able to remove these contaminants.
