Effects of moisture content of food waste on residue separation, larval growth and larval survival in black soldier fly bioconversion.
TL;DR: The results show that the residue can be effectively separated from the insect biomass by sieving using a 2.36mm sieve, however, sieving of the residue was not feasible for food waste at 80% moisture content, and reduced moisture content of food waste was found to slow down larval growth.

Reviewing the anaerobic digestion and co-digestion process of food waste from the perspectives on biogas production performance and environmental impacts
Sam L.H. Chiu,Irene M.C. Lo +1 more
TL;DR: Possible environmental impacts of AD and coAD in food waste treatment and recommends feasible methods to reduce the impacts are addressed and uncertainties in the life cycle assessment (LCA) studies are discussed.

Environmental assessment of food waste valorization in producing biogas for various types of energy use based on LCA approach.
TL;DR: The results show that biogas fuel as a petrol substitute for vehicle use is advantageous over other types of energy use in regard to human health and ecosystems, and it is also the best considering the government's future emission reduction targets set out for the power and transport sectors in Hong Kong.

Identifying key process parameters for uncertainty propagation in environmental life cycle assessment for sewage sludge and food waste treatment
Sam L.H. Chiu,Irene M.C. Lo +1 more
TL;DR: In this article, a selection approach with sensitivity analysis is proposed to identify the key process parameters and Monte Carlo simulation is further conducted to propagate the uncertainty of the identified process parameters, which indicates a significant advantage of using combined cycle gas turbine over combined heat and power unit for biogas utilization in Hong Kong.

Life cycle assessment of waste treatment strategy for sewage sludge and food waste in Macau: perspectives on environmental and energy production performance
TL;DR: In this article, a waste treatment strategy for sewage sludge and food waste in Macau is suggested with low environmental impacts and high energy production performance, which is based on life cycle assessment methodology.
