The global economy is not particularly energy-efficient. At current levels of consumption, we now waste about 86 % of the energy now used to maintain economic activity. This magnitude of waste imposes huge costs that constrain the robustness of the world economy. At the same time, however, there is an array of untapped cost-effective energy efficiency resources that can restore both energy and ...

The treatment of organic waste from household in the Danish-German border region is very diverse, the Danish area only uses incineration for the treatment while the German system includes combined biogas and composting, mechanical and biological treatment and incineration. Data on all parts of the organic waste treatment has been collected including waste composition data and data from treatmen...

Agricultural waste biomass generated from agricultural production and food processing industry are abundant, such as durian  peel, mango peel, corn straw, rice bran, corn shell, potato peel and many more. Due to low commercial value, these wastes are disposed in landfill, which if not managed properly may cause environmental problems. Currently, environmental laws and regulations pertaining to ...

Anaerobic digestion (AD) was introduced in Vietnam more than 10 years ago, but at a small scale to deal with agricultural wastes, manure, etc. Despite its many advantages, AD does not yet make a significant contribution to resolving Vietnams urban waste issues due to a lack of information, data and experience. This paper, using an energy model of food waste digestion, provides a usable source o...

Proper management of waste produced by human activity has been one of the major environmental concerns of modern societies. The use of the waste as a source of renewable energy is an interesting option, increasing the country's energy matrix, reducing the volume of waste and mitigating its toxicity. However, for a proper design and operation of a waste-to-energy plant, it is essential to know t...

India faces major environmental challenges associated with waste generation and inadequate waste collection, transport, treatment and disposal. Current systems in India cannot cope with the volumes of waste generated by an increasing urban population, and this impacts on the environment and public health. The challenges and barriers are significant, but so are the opportunities. This paper repo...

The thesis provides a presentation of the two conceptual models of industrial system material and energy flows in terms of sustainability; the dominant and the unsustainable throughput flow model and the potential future sustainable roundput model. These two material and energy flow concepts serve to illustrate the main research agenda of the emerging research and practical field of industrial ...
