An integrated model was established, including waste generation, collection, transportation, treatment, disposal and accompanying external proces...

Portugal, with 210,422 tonnes of glass recycled in 2011, did not attain the target for glass (227,060 tonnes), and this happened probably due to three factors: the reuse of this material since glass is a durable material, non-declaration of glass received by MRF (Material Recovery Facilities) and nondeposition in the specific stream. In 2011 were produced in Portugal, 5.159 million tonnes of Mu...

Composting is a biological decomposition process where microorganisms convert raw organic materials into relatively stable humus-like material. During decomposition, microorganisms assimilate complex organic substances and release inorganic nutrients. An adequate composting process kills pathogens and stabilizes compost organic carbon before the material is land-applied. In 1997, 27.2 million m...
