separation approaches affect organic contaminant levels. Thus, this fact sheet will focus primarily on heavy metal contaminants. Those metals of greatest concern in compost—cadmium, mercury, and lead—can be harmful to animals and humans at relatively low concentrations and tend to accumulate in soil, plants, and animals. For most of these potentially harmful metals, the levels in MSW composts a...

Agricultural operations generate large quantities of manure which must be eliminated in a manner that is consistent with public health guidelines. Meanwhile, construction and demolition waste makes up about 25% of total solid municipal waste. Co-composting of manure with construction and demolition waste offers a potential means to make manure safe for soil amendment and also divert constructio...

dependence on chemical fertilizer continually is increasing. continual increasing of using chemicalfertilizer causes nature pollution (e.g. water contamination). this has led researchers to aggressively investigate renewable fertilizer resources, biomass, to produce organic crops and reduced wastage. wormy compost is a bulk solid and biomass feed stocks. wormy compost flow is obstacle as it oft...
