Recycling

There was a programme on our local news yesterday about how the recycling percentages in this area of the country were below the national average of 44.8% and it set me thinking about our household average. It would seem the percentages are done on weight rather than cubic metres, or compressed dustbin lorries full. I did not know this as I thought with landfill, volume would be more important than weight. Given that it is weight and we recycle everything we can I would think our summer percentage was well above the national average. However, in the winter we have ash from solid fuel central heating and I would think it doubtful we could reach 10%. Just wonder what percentage others feel they reach?
