The Relationship

Thinking about innovations that reduce environmental impact and offer quality consumer goods is a way of proposing a future scenario governed by eco-efficiency values. Through an exploratory bibliographic and documentary research, which qualitatively analyses Kombucha authors and fermenters, this article seeks to identify the relationship between biomimetics and bacterial fabric production as an eco-efficient product in the fashion market chain. The general objective of this case study is to explain the fermentation process to encourage the search for raw materials inserted in the sustainability proposal.

This paper discusses the relationship between the Aboriginal heritage clearance process and the environmental impact assessment process. The current Western Australian legislation and the Murrin Murrin nickel project and other Western Australian projects are used as a case study, although similar methods and issues are applicable to most states within Australia. The paper investigates areas where delays may occur and proposes a model which can be implemented to maximise the level of certainty for a project.

Energy Products

Polygeneration systems produce multiple energy products (i.e. electricity, heat, cooling), and other biochemical products (biofuels and syngas). Such systems offer a sustainable approach in meeting the ever-growing demand of energy, while reducing its environmental impact. The optimal design of such systems should consider the design of the supply-chain in producing the targeted energy products to reduce the resource consumption and waste generation and to maximize its economic potential. One of the important considerations in designing such a system is whether to out-source its raw materials or to produce them in-house. The criteria for such decision strategies are assessed through economics, product demand, and environmental impact. One holistic way to measure the environmental impact of such system is to consider the triple footprint: carbon, water, and land. The objective of this work is to maximize the economic potential while maintaining the footprints at acceptable levels and simultaneously meeting product demands. In this study, an adoption of fuzzy multi-objective approach is presented wherein the economic potential is introduced as a constraint. Moreover, predefined fuzzy trapezoidal-shaped limits for the product demand constraints are used which mimics the probabilistic demand scenario for each of the product streams. Lastly, the triple footprint constrains is utilized to assess the environmental impact of the polygeneration. The technique is demonstrated using a modified industrial case study of a polygeneration system.

Agriculture has a substantial environmental impact. However, little research has been conducted on the relationship between agriculture’s environmental impacts and linkages, particularly for the key agriculture-based Pakistani economy. Additionally, the literature on environmental linkages rarely estimates multiple types of linkages in a single study. This study fills these critical research gaps. The study estimates the land, water, nitrogen, and CO2 impacts and linkages of Pakistan’s agriculture sector using an input–output model and the hypothetical extraction method. The results indicated that agriculture directly accounted for approximately 27%, 93%, 92%, and 1% of Pakistan’s total sectoral land, water, nitrogen, and CO2 impacts (LWNC), respectively. While the sector indirectly contributed almost 2%, 0.3%, 0.4%, and 0.4% of Pakistan’s total LWNC. The bulk of direct LWNC impacts were caused by agricultural purchases from downstream sectoral importers. The majority of the indirect LWNC impacts were induced by agriculture’s re-imports. The agricultural purchases from the downstream sector of “Food and Beverages” induced the greatest environmental impact. To ensure sustainable agriculture, particularly in Pakistan, the agriculture sector’s direct and indirect environmental impacts should be reduced not only through better management practices and technology, but also by focusing on intermediate sectoral sources of direct and indirect environmental impacts.

The Relationship

Environmentally conscious design or ecodesign plays one of the most important roles to create products with less environmental impact targeting the sustainable society. Manufactures often use checklists to support design improvements of products and to obtain eco-labels, such as Eco Mark in Japan. Current checklists are, however, insufficient to support designing products rationally because the relationship between the individual requirements of current checklists and environmental impact is undetermined. This paper proposes a method for supporting ecodesign assessment by developing a weighted checklist from a conventional checklist. This weighted checklist calculates ecodesign achievement based on the potential environmental improvement of each requirement, derived by the life cycle simulation. The result of a case study involving a digital duplicator showed the proposed method successfully clarified requirements that should be improved in the present product. When design improvements are applied, the assessment of the product’s CO2 emission is improved by 8%.

In recent times, there has been an indisputable need to move towards a more sustainable economy, known as a circular economy, which is basically aimed at reducing the consumption of newly extracted raw materials to manufacture products, and thus, reduces waste generation by recycling products beyond their useful life to ultimately close the economic flow of the product. For the economy generated by products to close the circle, it is essential to tackle the problem at the source, that is, the process to achieve the desired product should be conducted by designing the product with environmental criteria (eco-design) and analysing its life cycle from the extraction process to the point when it ends its useful life (LCA). This article presents an ECO + LCA methodology that provides designers with an easy way of visualising the effect of their design decisions on the final environmental impact of the product. This methodology was tested on a case study of a conventional desk, with four alternative scenarios presented and an assessment of their final impact with a cradle-to-grave perspective. The final design obtained reduces the environmental impact by more than 30% and reduces costs by more than 11%.

Abstract A review of the available literature concerning environmental impact assessment for industrial symbiosis has been carried out. The authors have recommended the use of life cycle assessment method for this purpose. It was stated that so far few studies presenting LCA results of industrial symbiosis have been published. Among the factors which contribute to the success of symbiotic exchange, the close location of collaborating companies has been often mentioned. This paper presents LCA results concerning the environmental impact of symbiotic gypsum transmission. Concepts of relative distance and critical distance for the case of industrial symbiosis were proposed and defined. Significant difference between critical distance obtained for particular endpoints were observed (3.5- 564 km). Application of Life Cycle Sustainability Triangle enabled the estimation of critical distance taking into account various impact categories. A sensitivity analysis indicated the relationship between critical distance and the means of transport which reflected the effect of scale. The critical distance determined for heavy trucks was 3.2 - 3.9 times longer than in case of lighter vehicles.
