The production of biogas is positioned as energy which can not only generate a source of renewable energy but also which recycles waste. In the context of sustainable development, the place of biogas is therefore essential. Several questions about safety issues, the harmonization of the regulations and the need to develop standards are discussed in this paper, based on the results of a workshop on biogas safety and regulation organized in November 2010 and the activities of the European Working Group on Biogas Safety and Regulation created after the workshop. The risks corresponding to the biogas production and use have been framed using iNTeg-Risk method and tools. Several deficits for risk management have been identified and a strategy to improve risk management proposed by the working group is presented at the end of the paper. [ABSTRACT FROM AUTHOR]

Colombian amazon has a wide biologic diversity, with silvester and cultured species which use potential and abundance identified them as an important bioactive compounds source. That represents a wide opportunity to innovate and develop processes and technologies in different engineering fields (chemical, mechanical and food engineering). This paper presents experiences when the problem of sustainable use of biodiversity is tackled from engineering in the Colombian amazonic region. [ABSTRACT FROM AUTHOR]
