Brian, I spent many years myself working in the 'recycling' industry, including several for a local council contractor. Thousands is spent, (wasted) on box ticking exercises, many gallons of fuel are burnt collecting a few tonnes of stuff that would otherwise have gone to landfill.
We had new 'state of the art' dustcarts with separate sections for collecting different materials in one go, apart from breaking down frequently, they also only managed about 2 m.p.g., a third of that of the vehicles they replaced..... However, this all helps to meet the targets set for us by Brussels.....
My main concern was the gas was released safely, unfortunately although I am sure you are competent, you never know if someone is going to cut through those pipes in the cellar, thus filling the space with the gas and possibly killing themselves in the process.....
