Energy from waste (or waste to energy) isn’t a new concept, however over recent years if has become more refined and more accessible in term of cost and legislation. In some countries there are still FIT (Feed in Tariffs) rates available – this is where the government pay you for electricity you put back into the grid.
How does it work?
The process involves 3 key stages. Stage 1 waste is burnt in the incinerator. Stage 2 – the exhaust fumes are fed through a heat exchanger to heat water. Stage 3 – the hot water is fed into a specialist craft engine that generates electricity.
The main considerations when looking at a waste to energy solution are: Do you have enough waste on a regular basis to fuel it? Is the waste of a suitably high calorific value to improve combustion? If no local FIT scheme how do you plan to use the electricity?
Once you’ve decided that W2E is a process you could benefit from, then ask one of the growing number of waste to energy companies to come out and do a no obligation survey and feasibility study.
