Hello,
I am attempting to design and construct a mesh/net/grill to assist waste pickers in East Africa to more efficiently extract recyclables from municipal solid waste. The net would be affixed to a structure so it would hang 1m off of the ground, waste would then be poured/thrown on/through the net from at least 2m off of the ground/1m above the net. The net would in practice 'catch' larger items (e.g. plastic, glass bottles) and sift dirt/food/organics/sand/etc. A few questions:
1. What would the optimal material design of the net be? What material would work best? At the moment, we would like to use thick steel bars (e.g. like a grill) as its locally available and very durable.
2. What would the optimal spacing be between bars/mesh/nets to ensure the average bottle is 'caught' but that dirt and organics fall through.
3. Is there any potential to line the net with a magnetic element to catch metals in the net?
Any questions, comments, advice would be highly appreciated.
Thanks,
Josh
