Environment Project Ambiente_Douro Interior is a case study at EWWR

14 April 2011 No Comment

The Project Compostagem _ “Construir” Sustentabilidade (Composting _ “Building” Sustainability), at the Douro Interior Concession, was considered a case study at the “European Week for Waste Reduction” website, developed by the European Commission and represented in Portugal by the  Portuguese Environment Agency. Once validated, this project, which aims to provide a response to green waste resulting from the deforestation and from the urban construction site, was presented in Brussels together with other actions developed in the European Community. It was initially in competition among 2639 Projects at European level. The official opening of the action happened at the Lote 1 construction site in Trindade, Vila Flor, Bragança, on November 24, 2009, in the presence of the Director-General of the company Resíduos do Nordeste EIM – an inter-municipal waste management company. Planting a native specimen (olive-tree), which may be found along the road and was identified for being cut, was a landmark of the initiative. The project will last two years, until the task is completed. In this sense, the Ambiente _ Douro Interior environment project intends to achieve the following objectives: promote the sustainable management of timber, resulting from the process of deforestation; promote a reduction in the treated waste, resulting from the urban construction site; and raising awareness among employees to the cycle of waste management, including: Waste generation / Recovery / Use as raw material. In the mean time, the project has already validated the reuse of logs (tree logs) in the dumps and the green matter in the black soils, the reduction of the Urban Similar Waste production (since collecting Urban Solid Waste in the north-east area costs 292 euros per container/month), and has promoted a positive image of Mota-Engil Engenharia before the Client, in the local community and among environmental entities. Once the Production has shown that the best choice would be to perform deforestation together with shaping operations and to bring tree logs to the dumps, the project Ambiente_Douro Interior has analysed the environmental benefits/implications of this activity and has concluded that this action could be framed in an Organic Recovery rather than in an energy recovery, thus respecting ancient agricultural practices. This solution provides technical added value, since it improves the efficiency of deforestation/shaping/earthworks operations, both for Environment and for Production. With the validation of the reuse of logs in the dumps and the green matter in the black soils, it is possible to improve the environmental process, by promoting the organic reuse of green matter and the productive process of deforestation/shaping, since performing these activities in a whole provides a better work management and optimises resources such as equipment, labour force and, essentially, time.
