Ecodesign methods focused on remanufacturing

Understanding the product's ‘end-of-life’ is important to reduce the environmental impact of the products' final disposal. When the initial stages of product development consider end-of-life aspects, which can be established by ecodesign (a proactive approach of environmental management that aims to reduce the total environmental impact of products), it becomes easier to close the loop of materials. The ‘end-of-life’ ecodesign methods generally include more than one ‘end-of-life’ strategy. Since product complexity varies substantially, some components, systems or sub-systems are easier to be recycled, reused or remanufactured than others. Remanufacture is an effective way to maintain products in a closed-loop, reducing both environmental impacts and costs of the manufacturing processes. This paper presents some ecodesign methods focused on the integration of different ‘end-of-life’ strategies, with special attention to remanufacturing, given its increasing importance in the international scenario to reduce the life cycle impacts of products.     

The European Commission's sustainable consumption and production and sustainable industrial policy action plan

The promotion of sustainable consumption and production patterns is enshrined as a key objective in the renewed European Union Sustainable Development Strategy (EU SDS). Sustainable consumption and production is arguably the most challenging aspect of the EU SDS. It requires changes to the way products and services are designed, produced, used and disposed of, taking into account producer and consumer behaviours. This paper reviews the European Commission's Communication on the sustainable consumption and production and sustainable industrial policy action plan, introduced on July 16, 2008. The paper examines the priority areas identified for action, the means adopted to improve energy and environmental performance of products as well as uptake by consumers. The paper concludes that the absence of mandatory quantifiable targets and deadlines and a reliance on both cross-sectoral and multi-level relationships are likely to weaken the ability of the action plan's fundamental objective of decoupling economic growth from resource use.     

Base-neutral extractable organic pollutants in biota and sediments from Lake Pontchartrain

A study was conducted to screen the three passes that link Lake Pontchartrain to the Gulf of Mexico via Lake Borne for the presence of EPA base-neutral (BN) priority pollutants and any other pollutants detected in significant concentration. Biota and sediment samples were collected and analytical procedures were developed for the trace analysis of BN organics in these matrices. Compounds identified include alkanes (normal, branched, cyclic), alkenes, aromatics, alkylated aromatics, polynuclear aromatic hydrocarbons and their alkylated derivatives, phthalates, ketones, furans, thiophenes, phenols, amines, nitriles, thiazoles, amides, aldehydes, alcohols, free fatty acids, fatty acid methyl and ethyl esters, phosphates, sterols. Concentrations were in the parts-per-billion range.
