This research assesses the environmental and economic benefits and costs of cleaner production projects formulated by smalland medium-sized enterprises (SMEs) participating in a sustainable supply program in Mexico. The program was designed as a public-private voluntary partnership to spur cleaner production dissemination in SMEs that are part of global supply chains. The study analyzes how pro...

This paper highlights some interesting facts on South African’s waste situation and management strategies, in particular the Integrated Waste Management. South Africa supports a waste hierarchy by promoting cleaner production, waste minimisation, reuse, recycling and waste treatment with disposal and remediation as the last preferred options in waste management. The drivers for waste management...

The regulation by law on recycling economy at the enterprise and ecological industrial park level serves as the base of leveled regulation by law on recycling economy. The recycle of enterprise internal sources is the key for developed countries developing recycling economy. Following the requirements of recycling economy, countries constitute relevant laws and regulations, offering an institut...

All three LIGO detectors have reached their design sensitivities. A sky-averaged detection range (SNR > 8) of more than 15 Mpc for inspiral binary neutron stars with masses of 1.4 Msol has been achieved with the two 4 km instruments. The fifth LIGO science started in November 2005 and ended September 2007. About 365 days of coincidence data have been collected. The feedback controls system is a...

There has been increased focus on recycling in Sweden during recent years. This focus can be attributed to external environmental factors such as tougher legislation, but also to the potential gains for raw materials suppliers. Recycling centres are important components in the Swedish total recycling system. Recycling centres are manned facilities for waste collection where visitors can bring, ...

This work addresses the rehabilitation of water contaminated with atrazine, entrapping it in a permeable and sustainable barrier designed waste materials (sepiolite) biomaterials (cork pine bark). Atrazine adsorption was assessed by kinetics equilibrium assays desorption tested different extraction solvents. Adsorbed atrazine 100% recovered from sepiolite using 20% acetonitrile solution, while ...
