Lca Case Study

Miscanthus lutarioriparius(M. lutarioriparius) in Lake Dongting District are in the situation of being discarded due to the government’s environmental policy, the decomposition of which will bring another pollution risk. The purpose of this study is to environmentally analyze the production of M. lutarioriparius-based oriented strand particleboards(M.OSB) as alternatives to the conventional artificial boards. The production systems were evaluated from a cradle-to-gate perspective using the Life Cycle Assessment(LCA)methodology. Our results showed that the M.OSB had an overall better profile than wood panels, identifying the production of starch adhesives and bio-fuels as the main environmental hotspots. It was also found that annual harvesting and utilization of M. lutarioripariuscould ease the burden to the environment during the decomposition of this plant, and further improve the environmental performance of M.OSB. Sensitivity analyses were conducted on the key parameters, suggesting that there are opportunities for improvement. This study provides useful information for enterprises and policymakers on where to focus their activities, with the aim of making the future of M. lutarioriparius utilization more technically and environmentally favourable.

Plantain and coffee are basic foodstuff of Colombian family standard basket, constituting important sources in the dynamism of the economy of the country. Given the importance of these products, five environmental impacts: global warming, aquatic eutrophication, terrestrial acidification, aquatic ecotoxicity and  use of soil were evaluated in three plantain crops associated with coffee in Antioquia Southwest (Colombia), for this purpose RECIPE 2008 method with a cradle to gate approach was used. Surveys and interviews applied to owners and employees of the farms, and to agents related to the production chains were carried out to obtain primary data, secondary data were taken from Ecoinvent 3.1 database. Consumption of resources and emissions were assigned to a functional unit of 1 kg of plantain and 1 kg of dry parchment coffee. Production systems consisted of four stages: establishment/propagation, production, postharvest and distribution. Plantain system generated less impact than coffee, and the stages that contributed the most to the environmental burden on impact categories in both crops were establishment/propagation and production. This is mainly due to the manufacture and the use of fertilizers.

Industrial symbiosis networks conventionally provide economic and environmental benefits to participating industries. However, most studies have failed to quantify waste management solutions and identify network connections in addition to methodological variation of assessments. This study provides a comprehensive model to conduct sustainable study of industrial symbiosis, which includes identification of network connections, life cycle assessment of materials, economic assessment, and environmental performance using standard guidelines from the literature. Additionally, a case study of industrial symbiosis network from Sodankylä region of Finland is implemented. Results projected an estimated life cycle cost of €115.20 million. The symbiotic environment would save €6.42 million in waste management cost to the business participants in addition to the projected environmental impact of 0.95 million tonne of CO2, 339.80 tonne of CH4, and 18.20 tonne of N2O. The potential of further cost saving with presented optimal assessment in the current architecture is forecast at €0.63 million every year.

AbstractAdditive manufacturing (AM) is a versatile technology that could add flexibility in manufacturing processes, whether implemented alone or along other technologies. This technology enables on-demand production and decentralized production networks, as production facilities can be located around the world to manufacture products closer to the final consumer (decentralized manufacturing). However, the wide adoption of additive manufacturing technologies is hindered by the lack of experience on its implementation, the lack of repeatability among different manufacturers and a lack of integrated production systems. The later, hinders the traceability and quality assurance of printed components and limits the understanding and data generation of the AM processes and parameters. In this article, a design strategy is proposed to integrate the different phases of the development process into a model-based design platform for decentralized manufacturing. This platform is aimed at facilitating data traceability and product repeatability among different AM machines. The strategy is illustrated with a case study where a car steering knuckle is manufactured in three different facilities in Sweden and Italy.

Recycled Concrete Aggregates

The search for environmental preservation and conservation of natural resources gives rise to new concepts and viable technical solutions on the path to sustainable development. In this context, this study’s main objective is to analyse the influence of recycled concrete aggregates (RCAs) on the development of pervious concrete, whose use as a floor covering represents an excellent device to mitigate the urban soil sealing phenomena. For this, mechanical and hydraulic tests were carried out, in addition to microstructural analyses and the assessment of its environmental performance. The results obtained were compared to reference studies also involving the incorporation of recycled aggregates. A pilot-scale case study was conducted, involving a parking space lined with pervious concrete moulded “in situ”. In laboratory tests, permeability coefficients and mechanical strengths compatible with the literature and above the normative limit for light traffic were found. The case study demonstrated higher permeability than in the laboratory, but the flexural strength was lower, being indicated only for pedestrian traffic. The environmental assessment showed that the RCA represents a positive contribution to the environmental performance of pervious concrete. Still, attention should be given to the recycled aggregate transport distance between the concrete plant and the RCA treatment plant.

High Yielding Varieties

Bangladesh is essentially self-sufficient in rice as a result of the successful adoption of new high-yielding varieties and irrigated summer production over traditional deep-water cultivation practices. The sustainability of the cropping system depends on farmers adopting integrated pest management (IPM) practices in preference to relying solely on insecticides for pest and disease control. Yet insecticide consumption in rice is increasing, in common with other crop-production systems in Bangladesh. It is probably only the poor economic returns from rice cultivation that prevent more widespread use of pesticides. Enlightened agrochemical companies such as Syngenta Bangladesh Limited have recognized that insecticide use in rice should be discouraged, and promote IPM options through their farmer field school (FFS) programme. This paper describes the results of a collaborative project to assist Syngenta to develop and incorporate mass trapping with sex pheromones into their FFS programme as an environmentally benign method of controlling the predominant insect pests of rice, stem borers.
