Kenya? or vermicomposer Heaven? 50 gallons wow!

Summer camps here frequently have the children only take the food they will eat. Each table has a daily contest to see which generates the least waste by weight. That might cut way down on the waste.

Or is this kitchen waste before it is put on peoples plates?

Before worms, rabbits, chickens and pigs might benefit.

You are not going to be able to start out handling 50 gallons a day. It will take a while. I would think a 100 square foot bin would be required. That might be 3 or 4 inches of waste per day. You might want a regular compost system and just feed the worms the choisest parts for a while. Strawberry tops and mellon.

I say start small with an educational bin and control the amount of food going in. As the girls learn what can and cannot go in worm bins, you can start putting bins right by the trash cans and have them separate their trash. Processing it all would be practically a worm farm -- which might be a worthwhile venture to raise money for the school?

I agree with EE that the scraps probably have a higher use feeding a pig or three, and then feed the pig manure to worms. (Provided, of course, this isn't an area with a lot of Muslims.)

Other options are a traditional compost pile and having them collected by a nearby farmer to supplement his livestock's diets. This could be temporary while the worms get going or an ongoing solution.

Hermetia illucens, the black soldier fly (BSF)can help too.

It can get that 50 gallons of waste down to 3 gallons of stuff the worms should love. And the local chickens will love you. Trade for eggs.

I agree with Eq, BSF / worms /chicken combo would be a great permaculture project!!! You would need over 100lbs of worms and a LARGE system to handle 50lbs+ daily, without BSF larvae or pre-composting first. I started with about 2 lbs of worms 13 months ago, and by contantly expanding my wormery into new compost piles, I currently estimate my herd at 50 lbs.. There is too much food waste (any is too much), but composting solves this problem. Good Luck! Pete
