This means that there is less risk of contaminants being added to the pile. Second, it is easy to avoid odor problems. Third, the state permitting process is relatively easy and the composting process requires little maintenance. Hancock County towns can expect volumes of up to 100 cubic yards of compost per 1,000 residents. Type I includes commercial residuals that do not contain significant amounts of human pathogens or heavy metals.
Examples are fish or blueberry processing wastes.
Type II includes sewer sludge and septage wastes. Because they contain human pathogens, these programs are the most regulated and require the most care. Post -consumer materials include mixed table scraps and food that has a high fat content. Post-consumer materials are more challenging to compost and may cause odor and vermin problems. Pure vegetable wastes can be treated as leaf and yard wastes and are subject to the same DEP permitting requirements.
