Composting

Hey Everyone!
I'm super into composting atm. We as Americans have millions of tons of trash going into the landfill every year. Not only is it going into a landfill where it wont decompose because it is covered from the elements which facilitate composting but the amount of fuel and pollution created by the process is staggering. SOOO much of this trash can easily be composted. All leaves and yard scraps, all paper, cloth, food and so much more.
There are many levels one can take it to but any amount is an upgrade!
I have 12 compost bins going. All the bins I make out of old pallets that I collect for free or out of these huge sheets of super tough cardboard that I get for free from various companies. I just make 3 sided bins tied together with old wire, fabric ripped into strips, rope or numerous other spare free materials.
I then collect leaves, wood chips, grass clippings, manure and all of my food scraps and combine them in the bins. Then life starts to grow and the material gets decomposed and within 2 months I have super nutritional perfect dirt!
This is awesome for anyone who grows anything and for anyone who wants to do something with there compost able materials besides throw them away.
The most important factors are moisture and air. Without moisture and air there will be virtually no decomposition. So ideally the compost gets turned every 3-7 days. When it gets turned you add water and more nitrogen sources. Coffee grounds from coffee shops is a wonderful source, manure is a really abundant free source, grass clippings are a really accessible free optimal source, and food scraps.
So for the ideal set up you would be turning it every week to introduce air, water and new nitrogen. With this set up one could have a pile of leaves turn into perfect dirt in 2 months. One only needs to add about 1 part nitrogen to 30 part carbon (anything dead). Really though if the compost pile is hot (ideally 120-170f) it is doing its job and nothing needs to be done. This wont last long though without turning, wetting, and adding nitrogen.
As for food scraps one wants to be careful with meat, dairy, or any protein based product. As certain bacteria is produced and certain heat levels are required to break it down. Also it may attack certain rodents. However it is not dangerous if you are just to do it out in the back somewhere and not use it for a long period of time. Its only if you are wanting to use it within a couple months that you may want to choose not to introduce them to the pile.
One can also achieve nice dirt in a longer period of time without turning if one were to build a more aerated system. Say a 3 sided pallet structure with a pallet on the bottom or a tube with holes running through the center out into the air. Then one could just keep the pile moist with watering once a week and covering with plastic. This would keep it warmer, keep the moisture from evaporating to quickly and also allow plenty of air. This is a great system for anyone who doesn't really need the dirt but wants to compost instead of land fill.
I am doing lots of compost and am happy to facilitate the integration of it into our lives. Contact me for any info any time.
