Co-composting of green waste and food waste at low C/N ratio.
In this study, co-composting of food waste and green waste at low initial carbon to nitrogen (C/N) ratios was investigated using an in-vessel lab-scale composting reactor. The central composite design (CCD) and response surface method (RSM) were applied to obtain the optimal operating conditions over a range of preselected moisture contents (45-75%) and C/N ratios (13.9-19.6). The results indic...
متن کاملEvaluation of In-vessel Composting of University Postconsumer Food Wastes
A prototype in-vessel composting unit, which includes air circulation and misting systems, was designed and built as a senior capstone project at the Bio-Resource Engineering Department at the University of Maine. The university Office of Resource Conservation and Recovery initiated a recycling program for postconsumer food waste generated by the residence hall commons areas in 1991. This food ...
متن کاملA Cost Analysis of Food Waste Composting in Taiwan
Taiwan’s Environmental Protection Administration (EPA) has enacted a food waste recycling policy since 2003 as an alternative of landfill and incineration for the final disposal of municipal solid waste. Recycled food waste is currently seen as a valuable material, especially when appropriate technology is developed. This paper conducts a cost/benefit analysis based on six cases of food waste c...
متن کاملIn-vessel co-composting of horse stable bedding waste and blood meal at different C/N ratios: process evaluation.
Abattoir blood meal is rich in nitrogen and its potential as a co-composting material for horse stable bedding waste was evaluated at two C/N ratios -32 (LBM, low blood meal) and 16 (HBM, high blood meal) - to improve the nutrient contents of the final compost. The mix was composted for 7 days in a 10 tonne/day in-vessel composter and cured aerobically. After 56 days ofcomposting, the ammoniaca...
