Identifying the potential for reducing food waste

New research has identified major drivers of food waste around the world. For example, in developing countries a lack of refrigeration technology is a major driver of food waste, and in the developed world low prices and increased choice encourage wasteful behaviour from consumers. Experts predict that drivers such as these will continue to increase food waste.

Uncertainties surrounding waste-sorting reduce household recycling

Reducing uncertainties about how and why recycling should be sorted could help to increase the amount of waste that is recycled, according to new research from Sweden. Uncertainties could be reduced by providing people with more information, but are more likely to be resolved by making the recycling systems themselves easier to use, the researchers suggest.

Remaking and revaluing ships sent for demolition

A recent study has examined how ships no longer economical to run are broken apart, reassembled and made into goods of new value, such as furniture, in Bangladesh. There are strong concerns about working conditions for those who work in this industry and ship breaking yards have recently been closed as they are considered hazardous. However, this study draws a valuable lesson from ship breaking in that 'things are but temporary configurations of material', which can, potentially, be endlessly reassembled, under safe conditions.

Dutch study shows policy effective in reducing packaging

Policies to reduce packaging are effective as long as they remain in place for at least five years and aim for an absolute reduction in packaging volume, experiences from the Netherlands suggest. A study of Dutch packaging policy found that packaging levels fell when such policies were in place, but that the amount of packaging has since risen as policies have become more short-term and focused on reducing packaging levels relative to changes in GDP.

Different recycling approaches may be needed for urban phosphorus

Sustainable management of phosphorus requires better information on how it flows through the environment via consumption and waste. New research from Sweden has found that 40% of phosphorus released by Gothenburg to the environment is in sewage sludge and a further 40% is in incineration ash. This suggests that phosphorus could be recycled from solid waste as well as from wastewater.

Rising energy demands could see the energy sector's water footprint increase by 66%

Increases in global energy requirements could lead to a rise in the energy sector's water footprint of up to 66% in the next 20 years, new research suggests. As part of a sustainable future, any energy mix must enable a reduction in greenhouse gas (GHG) emissions. However, some renewable sources, such as biofuels and large-scale hydropower, have large water footprints, a factor which must also be considered in energy policies, the researchers say.
