Possibility of Passive Aeration Composting Using Soil Draining Material

Effect of aeration rate on composting of penicillin mycelial dreg.

Pilot scale experiments with forced aeration were conducted to estimate effects of aeration rates on the performance of composting penicillin mycelial dreg using sewage sludge as inoculation. Three aeration rates of 0.15, 0.50 and 0.90L/(min·kg) organic matter (OM) were examined. The principal physicochemical parameters were monitored during the 32day composting period. Results showed that the ...

Co-composting of pharmaceutical wastes in soil.

AIMS Soils at a commercial facility had become contaminated with the pharmaceutical chemical residues, Probenecid and Methaqualone, and required remediation. METHODS AND RESULTS Soil composting was investigated as an alternative to incineration for treatment. In laboratory trials, a factorial experimental design was used to evaluate organic matter amendment type and concentration, and incubat...

Biodegradation of Degradable/Biodegradable Plastic Material in Controlled Composting Environment

The biodegradability of different plastic material was investigated under aerobic conditions. The samples were placed in the compost pile and were checked over 15 weeks. After the expiration of the experimental period it was found that the samples with the additive (samples 1, 2, and 3) had not decomposed, their color had not changed, and that no degradation or physical changes had occurred. SE...

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...
