Sustainable Haringey has organised a visit to the Eco Park on the North Circular Road (previously known as the Edmonton Incinerator). It takes our* residual waste which is burnt and converted into electricity, and our food and garden waste which is made into compost. There is a limit of 12 on the visit so booking essential. To book a place email email@example.com. Further information 020 8347 7684.
*and also that of Barnet, Camden, Enfield, Islington, Hackney, and Waltham Forest (according to Wikipedia, it is Britain's largest incinerator).
(This is their fifth visit this year - all the others have been over-subscribed, but they are looking for more takers for this one!)
