Delayed addition of nitrogen-rich substrates during composting of municipal waste: Effects on nitrogen loss, greenhouse gas emissions and compost stability Article

Abebe Nigussie; Sander Bruun; Thomas W. Kuyper (2017)

Municipal waste is usually composted with an N-rich substrate, such as manure, to increase the N content of the product. This means that a significant amount of nitrogen can be lost during composting. The objectives of ...
Earthworms change the quantity and composition of dissolved organic carbon and reduce greenhouse gas emissions during composting Article

Abebe Nigussie; Sander Bruun; Andreas de Neergaard; etal (2017)

Dissolved organic carbon (DOC) has recently been proposed as an indicator of compost stability. We assessed the earthworms’ effect on DOC content and composition during composting, and linked compost stability to greenhouse ...
Vermicomposting as a technology for reducing nitrogen losses and greenhouse gas emissions from small-scale composting Article

Abebe Nigussie; Thomas W. Kuyper; Sander Bruun (2016)

Thermophilic composting produces a significant amount of greenhouse gases. The objectives of this study were (i) to evaluate the effectiveness of vermicomposting to reduce nitrogen losses and greenhouse gases emissions ...
