The main thematic sessions were :
Innovative Waste Solutions
Sustainable Waste Management
Waste To Energy
Regarding Waste to Energy the conclusions were that, in line with the new EU directive of 2008/98, Waste to Energy is getting higher in the hierarchy of Waste Management and the percentage of the use of this technology will be higher within the next years in Europe, USA and also in developing countries in order to reduce use of fossil fuels.
Two technical visits took place with participation of Synergia (WTERT).
1. Visit to Lipor s Integrated Waste Management System
Lipor (Intermunicipal waste management service of greater Oporto) in the entity responsible for the management, valorisation and treatment of municipal solid waste produced by eight associated municipalities. There are Espinho, Gondomar, Maia, Matosinhos, Porto, Povoa de Varzim, Valongo and Vila do Conde. Lipor was originally created as an association of municipalities in 1982 and it has come to implement an integrated management of waste. Lipor treats around 500,000 tonnes of municipal solid waste, produced by 972,000 inhabitants per year. Sustaining modern municipal solid waste management concepts such as the adoption of integrated systems and minimising disposal in landfills, Lipor has developed an integrated treatment, valorisation and confinement strategy for municipal solid waste based on three main components: Multimaterial valorisation, organic valorisation, energy recovery. All these are complemented by a sanitary landfill for the final disposal of residuals.
Visit to Lipor s Recycling Circuit
In the Multimaterial Lipor Recycling Circuit, the whole process was seen from their deposition in the Eco- Containers and Drop-of-sites to their passage by the Sorting Plant, where they are sorted and baled for recycling. Lipor’s Sorting
