Abstract:

The use of renewable waste for bioenergy production is in discussion because of the concurrence to the food or animal feed. The treatment of organic waste is necessary in order to keep clean the environment. The combination of those proposals, the waste utilization and the production of renewable energy can be combined with several techniques. In Vietnam the energy demand will increase rapidly in the next years, because a lot of people do not have access to electricity. The development of power sources is limited mainly to large central power plants using hydropower and traditional fossil fuel

Abstract:

This master thesis investigates the potential use of biogas from organic residues in the area of the cities of La Paz and El Alto in Bolivia. The two cities have currently a contamination problem and biogas emerges as opportunity for both waste management and energy generation. There are approximately 274 500 tonnes/year of residue that can be used to produce biogas. This amount of residue can generate approximately 33,500,000 m3 of biogas. The advantages and disadvantages of five different digester types (the smaller tubular digester, the fixed dome digester, the floating drum digester and th

Abstract:

Several operational and environmental conditions can result in poor biogas yield during the operation of anaerobic digesters and anaerobic bioreactor landfills. Over time, anaerobic co-digestion and leachate blending have been identified as strategies that can help address some of these challenges to improve biogas production. While co-digestion entails the co-treatment of multiple substrates, leachate blending involves combination of mature and young landfill leachate. Despite the benefits attributed to these strategies, their impact on recirculating bioreactor landfill scenarios and anaerobi

Abstract:

The increasing concern about water quality and energy demand promotes the development of innovative and low-cost processes to improve the nutrient uptake and energy efficiency of existing wastewater treatments (WWT). In this context, the inclusion of a microalgae system (MAS) in the flowsheet of a WWT plant represents a sustainable alternative to conventional technologies, as it combines a low-cost nutrient uptake system with the production of biomass suitable for biofuel production. However, at present, the energy required to cultivate and process the algae cells is often too high to justify

Abstract:

For enhancing anaerobic sludge digestion and biogas recovery, an increase in organic load rate (OLR) from 1.0 to 3.0kgVS/(m3·day) was imposed upon a new anaerobic digestion process combined with a sludge recirculation.

The hypothesis of this study was that increasing continuously OLR from 1.0 to 3.0kgVS/(m3·day) in a pilot-scale anaerobic digester with recycled sludge would not badly influence the digester stability, based on which biog

Sustainable waste management remains a great challenge for many cities throughout the world.

In this thesis, these sorts of systems are referred to as biogas solutions. In Brazil, the eight largest economy in the world and by far the lar

Abstract:

Organic matter and nutrients present in urban and industrial wastewater should be removed or valorised to reduce its impact on the environment. Conventional wastewater treatments are focused on the removal of these pollution sources at the minimum cost. The idea of resource recovery from wastewater is changing the concept of the conventional wastewater treatment plants that tend to incorporate little by little processes as anaerobic digestion, MBR, biofilm, granulation, etc. However, their application to obtain reusable by-products from wastes should be cost effective.

Abstract:

Die anaerobe Vergärung von nachwachsenden Rohstoffen und Gülle zur Biogasproduktion als regenerative Energiequelle erfährt seit einigen Jahren einen erheblichen Boom. Dabei werden in Deutschland in der Regel Nassvergärungs-Biogasanlagen betrieben, in denen kontinuierlich Energiepflanzen und Rinder- oder Schweinegülle gemeinsam eingesetzt werden (Kovergärung). Aber auch die alleinige Nassvergärung von Energiepflanzen ohne Gülle (Monovergärung) ist möglich. Häufig fehlen jedoch belastbare Daten zur Auslegung der Biogasanlage und für die Früherkennung kritischer Belastungszustände. Im vorliegen

Abstract:

<p>This paper reports on environmental impacts and health hazards as a result from inadequate management of organic household waste in developing countries. It gives details of water and soil contamination, air pollution and spread of diseases through expanding breeding grounds for pathogens, vectors and rodents. To manage this waste flow sustainably, decentralised composting and anaerobic digestions technologies have been studied to give an overall picture of existing appropriate technologies, including: windrow, box/bin/barrel, THM, aerated static pile, in-vessel, vermi, ARTI compact biogas

Anaerobic digestion technologies have been utilized in Vietnam for more than 30 years with thousands of domestic small scale plants, mostly for agricultural and livestock wastes.

Abstract:

The use of biofuels instead of conventional fossil derived fuels is becoming an increasingly crucial topic for future energy systems where environmental issues are also taken into account. Biomass exploitation, including biowaste, appears as a promising means for the energy production and also it contributes to the carbon dioxide emissions reduction. Among the different techniques for biomass exploitation, interesting aspects are covered by the dry anaerobic fermentation of organic waste (OFMSW). In addition also interesting aspects can be achieved by the anaerobic digestion of sewage sludge i

The UK buries about 100 million tonnes of waste a year, of which 25% is municipal solid waste (refuse). The environmental impacts from gas and leachate releases are known and direct risks to health from landfill are reported. Europe has agreed to a Landfill Directive which has set targets for the stepwise reduction in biodegradable municipal waste going to landfill. The anaerobic digestion of municipal solid waste in controlled bioreactors is an area that could play an important role in overall evolution towards sustainability by recovering biogas and organic matter.
