On Barriers to Institutional Composting and Commercial Composting Sustainable Development

Introduction During this research project, we attempted to identify and overcome barriers and resistance to the establishment of organic waste (leaf and yard waste and food waste) collection and diversion programs within public and private institutions in the region that generate large amounts of organic wastes. As only 2.4% of food waste (EPA 1997) is recovered or recycled, there is 97.6% of f...

Optimizing composting parameters for nitrogen conservation in composting.

A central composite experimental design was used to investigate the influence of environmental composting parameters (moisture, aeration, particle size and time) for legume trimming residues, used on soil restoration, on the properties of products obtained (organic matter, Kjeldahl-N, C/N ratio and nitrogen losses (N-losses)) in order to determine the best composting conditions. A second-order ...

Digital Composting using Chroma

In television and movie industry a so-called "blue box" technology is used, when an object in the foreground (e. g. a person) needs to be placed on a different background (e. g. a computer-generated 3D scene). However, it is often not economically justifiable to build a "blue box", therefore other methods can be used to extract the foreground object and remove or replace bac...

Composting Unamended Chicken Manure

Normally, manures are composted with amendments. However, a large commercial egg producer in Ohio i s composting unamended chicken manure. Studies were done to characterize this composting, both in situ and in pilot-scale vessels. While overly wet material can hamper initial operation, the general progression dries the material and produces a granular output that is below 20 percent (wet basis)...
