Compost System Efficiency Study

Two systems, same inputs by weight, measured on time, volume reduction, temperature and final quality.

Running two methods properly side by side for eight weeks is a real study and the results are rarely as expected. Fast systems produce coarser compost. Slow systems produce better material and tie up space.

The page has the two protocols, the measurement schedule, a results table and an efficiency analysis. It also asks what efficient means, since the answer depends on whether the constraint is time, space, labour or quality. That question is the most valuable line on the page.
