Viresco Solutions is a consulting firm based in Calgary, Alberta, Canada. Its core business is greenhouse gas offset policy development and implementation, greenhouse gas emissions quantification, sustainable supply chain development, environmental offset methodology development, and providing technical assistance to others undertaking carbon offset project development. Its clients include industry and non-governmental associations, large private sector companies, and local, provincial and federal governments.

Alcohol burning stoves based on methanol can be used to supply a cooking service, water heating and heating of buildings. The technology can be applied in households, institutions (e.g. schools) and industries where it is used for boiler heating.

Thermal gasification of municipal solid waste (MSW) is a chemical process that generates a gaseous, fuel-rich product. This product can then be combusted in a boiler, producing steam for power generation. Just as with combustion of MSW, thermal MSW gasification does not necessarily compete with recycling programmes, but should be considered complementary in any generically constructed MSW plan.

IIGE is a research institute that promotes development, innovation and transmission of technology focused on energy efficiency and renewable energy. The institute aims to contribute to the sustainable development of the Ecuadorian society, through the implementation of energy efficient and energy renewable policies and projects.

The Global Environment Centre Foundation (GEC) is an entity that supports the UNEP’s International Environmental Technology Centre (IETC), based in Japan. GEC is dedicated to the transfer of environmentally sound technologies, in both developing countries and countries with economies in transition. The foundation aims to contribute to Japan’s international efforts on the environment, sharing project collaborations as well as promoting Japan’s rich conservation knowledge and experience in developing nations.

The concern about the effective use of the unused wood biomass from energy security or a perspective of CO2 reduction is increasing. The knowledge corresponding to the multi-energy supply which paired the biological oil manufacture technology from the woody biomass by rapid thermal cracking gasification and biological oil-ization is held. (The level of practical use is reached by joint research with a plant manufacturer.) In addition it owns the knowledge about the circulation and storage corresponding to the properties of biological oils flammability etc.

This invention provides an integrated power generation process with improved efficiency. It relates to electric power generation in a fuel cell driven by the products of dry gasification of solid carbonaceous fuels by flowing CO2 gas. This high temperature single step process recycles CO2 by converting it into a valuable gaseous fuel. In contrast to conventional steam gasification this new process does not require water which preserves an important resource. It also supplies the oxygen required for the oxidation reaction through an ionically selective solid oxide electrolyte membrane.

Background: Gases that occur in nature or that are produced in industrial processes often contain carbon dioxide (CO2). Because of process requirements or because of the end result desired it is sometimes desirable to remove carbon dioxide from a mixture of CO2 and other gases.

The report profiles agencies whose technologies have been recognised by the Ministry of New and Renewable Energy, Government of India. It includes key agencies involved in various stages of the supply chain of biomass gasification for thermal and electrical end-uses, such as research and development, manufacturing, marketing and operation and maintenance.

The technology can be applied in households, institutions (such as schools) and industries where it is used for boiler heating. Biomass gasification household stoves work by a high temperature conversion of biomass in a restricted oxygen environment to a mixture of nitrogen, carbon monoxide, hydrogen, and methane. The hydrogen and methane are then burned without emitting pollutants. For larger applications pure oxygen may be used which gives a higher calorific value gas without the nitrogen.
