“…Life cycle assessment [17] is an established technique for environmental analysis wherein system inputs (materials, energy, and others) are adequately correlated with the outputs (product, waste, and emissions) using standard methodologies with the aim of improving the system. However, LCA of waste treatments are often based on a single treatment technique coupled with uncertainties, which make them case specific with data unconnected to specific plant or functional scenarios [18,19].…”

Abstract:The environmental performance of industrial anaerobic digestion (AD), pyrolysis, and integrated system (AD sequence with pyrolysis) on food waste treatment were evaluated using life cycle assessment. The integrated treatment system indicated similar environmental benefits to AD with the highest benefits in climate change and water depletion in addition to the increased energy generation potential and the production of valuable products (biochar and bio-oil). Pyrolysis results illustrated higher impact across water, fossil fuel, and mineral depletion, although still providing a better option than conventional landfilling of food waste. The dewatering phase in the AD process accounted for 70% of the treatment impact while the pre-treatment of the food waste was responsible for the main burden in the pyrolysis process. The study indicated that the three treatment options of food waste management are environmentally more favorable than the conventional landfilling of the wastes.

“…The strong dependence of each SAM on local conditions captures the local specific conditions in the modeling of MSWM system, allows identifying critical problems and proposing improvement options adapted to the local specificities [47], as emphasized by Laurent,(2014) In this regard, the quality of the provided support to decision and policy-makers is strongly dependent on a proper conduct of the life cycle inventory construction [48], improved access to waste data will help craft appropriate MSWM strategies towards sustainable MSWM. Therefore, this study suggests building a broader life cycle inventory database, which includes the basic statistics of MSWM unit process inputs and outputs, operation parameters and algorithms in the calculation, and allows users and researchers in their subject area to search for data specific to unit processes, structures, equipment, or various life cycle inventory (LCI), which is a basis for any sustainability assessments.…”

This study develops a sustainability assessment model for analysis and decision-making of the impact of China's municipal solid waste management enhancement strategy options based on three waste treatment scenarios: landfill disposal, waste-to-energy incineration, and a combination of a material recovery facility and composting. The model employs life cycle assessment, health risk assessment, and full cost accounting to evaluate the treatment scenarios regarding safeguarding public health, protecting the environment and conserving resources, and economic feasibility. The model then uses an analytic hierarchy process for an overall appraisal of sustainability. Results suggest that a combination of material recovery and composting is the most efficient option. The study results clarify sustainable attributes, suitable predications, evaluation modeling, and stakeholder involvement issues in solid waste management. The demonstration of the use of sustainability assessment model (SAM) provides flexibility by allowing assessment for a municipal solid waste management (MSWM) strategy on a case-by-case basis, taking into account site-specific factors, therefore it has the potential for flexible applications in different communities/regions.

“…This often leads to a different ranking of substances in terms of major contributors to the environmental impact [42][43][44]. As a result, many LCA practitioners exclude some potentially important impact categories from assessments [45], and they recognize that LCIA is one of their main limitations [40]. Therefore, with the aim of establishing a more reliable use of the LCA tool throughout Europe, the Joint Research Centre [46,47] has recently created a handbook to help eco-designers to make the correct choice for calculating environmental indicators.…”

Application of Eco-Design and Life Cycle Assessment Standards for Environmental Impact Reduction of an Industrial Product

Eco-design is included within the framework of the standard for "Environmental management systems-Guidelines for incorporating Eco-design" (ISO 14006:2011). Eco-design process, as defined in standard, has six steps: (i) Specify product functions; (ii) Environmental assessment of products; (iii) Strategies of improvement; (iv) Environmental objectives; (v) Product specification; and (vi) Technical solutions.Step (ii), determination of the stage or process of the product life cycle that has the highest environmental impact; this is perhaps the most controversial step because the standard does not specify which tool should be used. This lack of specification has generated some distrust with regard to eco-design, hindering its development. In order to make a trustworthy eco-design, Life Cycle Assessment (LCA) should be applied as a tool for environmental impact quantification. The main objective of this work is to apply standardised eco-design methodology for the reduction of the environmental impact of an industrial product in Spain using LCA as a tool for the environmental product assessment. LCA standardised process (ISO 14040,14044:2006) is included in the eco-design process. A glass container intended for cough syrup delivery has been selected as an industrial product to be eco-designed. Following the methodology described, the overall normalised impact decreased 35.1% when a PET container substituted a glass container. Environmental impacts have been reduced following standardised eco-design and LCA methodologies, serving as an example to industry and administration regarding how to eco-design with the confidence of obtaining reliable results.
