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]

Knowing the amount and type of Domestic Solid Waste (DSW) that is deposited in the landfill gives us the possibility to consider options in how to make sustainable use of it. Waste from any location, if properly handled, can be turned into the raw material for other processes. The aim of this study was to quantify the components of the DSW likely to be recycled, deposited in the landfill in the city of Ensenada, Baja California, Mexico, so that they could be valued on the market as recyclables. The average weekly market could be 643.67 tons of food waste for composting, 389.45 tons of paper and cardboard, 217.55 tons of plastic, 78.81 tons of glass, 32.20 tons of metal and 8.11 tons of aluminum. This should result in a total of approximately MXP $ 911,224.18 (USD $ 71693.48) for the marketing of major recyclables. [ABSTRACT FROM AUTHOR]

Economic growth in Bogota and its region will produce important changes in urban development and mobility. Increases in private vehicle ownership in the next decades will contribute to urban sprawl and car dependency in a development pattern similar to the one lived by North American cities. This paper underlines the policy and strategy to be adopted by Bogota District in order to prevent a path of non-sustainable development, promote a more inclusive city and an efficient integration with the Region.

How sustainable is a transport scheme is not easy to define. There are certain aspects in which schemes as the London congestion charge can or can't contribute to the improvement of the quality of life and the rational use of resources. Through 3 criteria: economic, social and environmental, the following paper reviews the characteristics of this transport scheme based on the concept of sustainable mobility to conclude that socially speaking it has been successful while economically it can be improved while its environmental effects are still to be established.
