Social sustainability assessment of conversion technologies: Municipal solid waste into bioenergy using Best Worst Method

The majority of sustainability assessments of the bio based industries are primarily focused on the environmental and economic aspects, while social impacts are rarely considered. While overlooking social dimension can have a serious harmful impact across supply chains. To address this issue, this study proposes a modified systemic approach for a social sustainability impact assessment of the te...

Liquid Fuels by Low-severity Hydrotreating of Biocrude

Biocrude (fast pyrolysis oil from wood) was hydrotreated to minimize the negative aspects of this fuel. The instability of the oil was reduced by reaction of the most unstable functional groups. Concurrently, the oxygenated component of the oil was also reduced, resulting in an improved energy density. Changes in the physical handling properties were also modified. All of this change was accomp...

Conversion of waste cooking oils into environmentally friendly biodiesel

Background There has been an alarming increase in the dumping of Hong Kong’s municipal solid waste (MSW), predominantly food waste, in landfill (9,547 tonnes of MSW per day in 2013) [1]. One way of promoting an environmentally friendly method of minimising food waste is to turn the waste into energy by producing biodiesel from waste cooking oils. Biodiesel is a biodegradable fuel that can be ma...
