Decoupling municipal solid waste generation and economic growth in the canton of Vaud, Switzerland

Jérôme Chenal, Rémi Jaligot

Switzerland is one of the largest producers of municipal solid waste (MSW) per capita. The principle of decoupling attempts to evaluate the relationship between consumption and production, and to measure the relationship between an activity and its impact ...

Valuing waste as resource: Mechanisms of change in developed and developing countries

Rémi Jaligot

The total municipal solid waste (MSW) generated worldwide in 2012 was approximately 1.3 billion tonnes. Were all countries to continue to generate waste at the current rate of high-income countries, total waste generation could reach 5.9 billion tonnes by ...

Catalyst design for the transformation of CO2 into value-added products

Felix Daniel Bobbink

The mass-utilization of fossil resources has led to a dramatic increase in carbon dioxide (CO2) production, most of which is released directly into the Earth's atmosphere, resulting in global warming. Efforts to contain CO2 emissions and to capture, store ...

Seasonal variation of municipal solid waste generation and composition in four East European cities

Christian Ludwig

The quality of recyclable and residual municipal solid waste (MSW) is, among other factors, strongly influenced by the seasonal variation in MSW composition. However, a relatively marginal amount of published data on seasonal MSW composition especially in ...

Above- and below-ground methane fluxes and methanotrophic activity in a landfill-cover soil

Graciela Gonzalez Gil

Landfills are a major anthropogenic source of the greenhouse gas methane (CH4). However, much of the CH4 produced during the anaerobic degradation of organic waste is consumed by methanotrophic micro-organisms during passage through the landfill-cover soil ...
