Flow-Through Vermicomposter
The purpose of this tool is to provide a space to vermicompost a variety of waste ( animal manure, food scraps, or other organic waste) with worms and produce safe worm castings, a valuable resource. The worm castings can be utilized in a variety of ways on the farm or sold to other farms and gardeners.
Black Soldier Fly as a Feed Alternative for Aquaculture
Main Street Farms received a SARE Farmer grant for on-farm research of Black Soldier Flies larvae (BSFL) as an alternative food-source for aquaculture and livestock. We plan to raise and breed BSFL in a heated green house year-round to find the ratio of pounds of larvae to pounds of food waste can be produced in a given month. The larvae will be fed cafeteria food waste, coffee grounds, and compost from other areas of the farm.
Urine Use as Fertilizer on the Home Scale
There is a long history of recycling of human urine as fertilizer. This document answers many of the questions that we are often asked about the use of urine as a fertilizer on the home-garden scale.
Guide to Creating a Community- Scale Urine Diversion Program
This document describes the work of the Rich Earth Institute (Rich Earth) in detail, primarily to support those seeking to move this work forward in their own regions. We cover the process of starting up a community-scale urine diversion program (UD program) and key elements of its operation. Throughout the document we also reference the UD program Toolkit, where we have publicly made available a host of open source documents, presentations, and other materials to support those starting a UD program. Please do let us know if you start a UD program! We’d love to hear what happens, and assist if we can.
Stackable flow-through Vericomposter
A year ago I built some portable, stackable vericomposter boxes that have been successful in raising red worms in central NC through all seasons. This project shows that vericomposting can be effective in a small space, with inexpensive and/or free materials, from easily obtainable materials.
Community Compost Exchange
Incentivized Community Compost System
Slug Trap & Composter
Slugs are damaging crops and farmers are trying to kill the slugs. We found a way to efficiently trap slugs without hurting them, so that farmers don’t have to worry about crop damage.
Truck Bed Liner Compost Tea Collector
This concept recycles a Truck Bed Liner. The tool produces a mid sized compost facility, and unlimited amounts of compost tea.
Compost Sensor
Compost Sensor is an open source sensor system for monitoring and recording the temperature and moisture of active compost. It is for small scale commercial composting operations to help with quality control and the certification processes. http://www.instructables.com/id/Compost-Sensor/
Remote Compost Monitor
As part of a master composting class I created a composting and computer science lesson plan. It teaches composting, and then includes a project where students create an arduino powered device to collect temperature and moisture levels of a compost pile (or anything, really) and then send it to a web application they create. Instructions, materials, and source code for everything is here. There are tons of ways it could be improved, as it was only designed to teach concepts. My plan was to leave it here and move along to another project, but I figured there might be some folks out there that want to collaborate make it a more useful monitoring product!
