Strategies of sustainable development in practice

Nowosielski R., Spilka M., Kania A.

Journal of Achievements in Materials and Manufacturing Engineering

2007

Vol. 20, nr 1-2

555-558

Purpose: The paper presents a necessity of the sustainable consumption, production and technology patterns to the companies introduced. Design/methodology/approach: In this article replacing unsustainable consumption and production model into sustainable consumption and production model proposed. Taking into consideration that resources are used beyond the earth's carrying capacity, leading to high waste yields and emissions into the atmosphere and water and inefficient use of natural resources, the only way to improvement this is sustainable development. Findings: The paper presents using sustainable production indicators to estimation of technological processes environmental influences. Indicators have increasingly been used as a tool to measure progress toward sustainable development at different levels - national, regional, local and company. Research limitations/implications: Using the sustainable consumption, production and technology are the only way for better life quality achievement. Practical implications: In the papers presented that achieving sustainable production, consumption and sustainable technology will require changes in industrial processes, in the type and quantity of resources used, in the treatment of waste, in the control of emissions and in the products produced. It is also necessary a development of production indicators to evaluate sustainable production. Originality/value: This article presented a necessity of a new approach to environment protection through sustainable production, consumption and sustainable technology. Sustainable consumption and sustainable production are complementary strategies for making economies more sustainable.

Application of the sustainable materials technology model

Purpose: The paper presents a possibility of the sustainable technology model to the materials technological processes galvanic treatment used. Design/methodology/approach: The article includes analysis and estimation of the nickel and chromium coated on the metal elements. To selection of the best solution (about the least negative environmental influence) simple genetic algorithm was used. Polyoptimization makes possible selection of the optimum solution in view of several criteria, especially environmental. Findings: The conclusion of the work shows a possibility connecting of sustainable technology model with multiobjective optimization. This approach gives basis to collection of many modernization variants and selection of the optimum variant. Research limitations/implications: The enlargement of quantity and kind of criteria (except environmental criteria, e.g. quality, efficiency, costs, etc.) can narrow down the area of proposed solutions selection. The problem is the suitable introduction of these criteria to objective function. Practical implications: The solution presented in the paper can apply in the industry to estimation and selection of a group technological processes which characterize different environmental influences. To modernization variants optimization, except genetic algorithms, can be used other methods of polyoptimization. Originality/value: The paper presents searching for optimum solutions of the technological proces modernization with regard to environmental criteria with polyoptimization used.
