Pig Waste Composting

This set of images definitely represents a “blast from the past”. I took them while I was working on my (ill-fated) masters program at the University of Guelph (04/05). My project involved composting liquid pig waste mixed with straw, using small (by industrial standards) in-vessel composting systems (built by Transform Systems in B.C.), and measuring the ammonia gas being released. The idea was to see if a brief “precomposting” period, followed by vermicomposting would help to reduce the overall amount of ammonia being released.

All I wanted to to, of course, was play with my worms and see how well they would grow in the material – which probably helps to explain why I am an online worm compost educator and entrepreneur – NOT an academic!
