Purpose: In this article an attention to environmental aspects, especially the necessity of recycling usage in the engineering design was paid. Design/methodology/approach: In the paper characteristic of engineering design and individual stages of this process, tools which designer uses to its realization were presented. Moreover, the factors which should be consider in the designing process were described. Findings: In this article, on the basis of engineering design methodology the ecodesign algorithm in which the principles of recycling were considered was proposed. Research limitations/implications: Design for recycling helps protect the environment and creates a sustainable means for conserving our resources. Recycling it is not only the usage of the secondary resources. It should be the system of materials circulation, consciously usage in the process of products designing which can be many times processed. Practical implications: Ecodesign is a new approach to designing and it depends on identification of the environmental aspects connected with product and consideration them to the designing process already on the early stage of product development. Originality/value: The worked out ecodesign algorithm systematizes workings performed during designing process and shows the meaning of the ecological aspect (necessity of recycling in it) in this process.

Purpose: Metallurgical process generates many solid, gaseous and liquid wastes. Nowadays when environmental protection is one of the most important problems and when pollution limits are very tight as well, problem of the metallurgical wastes is a strategic one. Design/methodology/approach: In present days the metallurgical and foundry plant have to utilize their own wastes, especially these which are the most dangerous and toxic or have to render harm of its and transfer to another industry branch for further utilization. Nowadays the issue of wastes management has the place both in industrial practice and scientific field too. The presented work is a result of such an approach, where a cooperation between scientific and industrial partners gives good economical and ecological results. Findings: One of the very efficient method of utilization of furnace dusts from any melting furnace or the finest fractions of charging materials is pneumatic powder injection directly into molten metal bath.The method is pretty easy and cost effective in various conditions and its flexibility allows to implement it in almost every foundry or metallurgical plant. Research limitations/implications: Further experiments should be carried out to solve some additional problems appearing during powder injection processes to make them more efficient in various technological conditions. Practical implications: Nowadays in Poland operate more than ten industrial stands for powdered carburizers injection, installation of furnace dust injection back to the melting furnace or pneumatic inoculation of alloys (mostly in cast iron foundries). Originality/value: The paper presents a few modern solutions for recycling and utilization of furnace dusts (in cupolas and EAF’s) and pneumatic carburization with use of powdered carburizers which are very often in form of grinded graphite electrodes wastes. All of the mentioned results and method had been developed in Department of Foundry and some of the designs had been previously patented.

Wdrażanie czystych technologii węglowych i opracowywanie nowych rozwiązań technologicznych w obszarze produkcji i utylizacji węgla jest nieodzowne, aby te procesy w minimalnym stopniu wpływały niekorzystnie na środowisko naturalne oraz na zmiany klimatyczne. Konkurencyjne oraz przyjazne dla środowiska produkcja i utylizacja węgla stają się równocześnie trwałymi podstawami bezpieczeństwa energetycznego Polski, jak i Unii Europejskiej. Wizerunek węgla w Unii Europejskiej, a także w Polsce, gdzie produkcja energii elektrycznej opiera się głównie na jego wykorzystaniu, nie był dotychczas najkorzystniejszy. W artykule zarysowano koncepcje zmiany tego wizerunku w Polsce z uwzględnieniem znaczenia węgla, jako nośnika energii pierwotnej i potrzeby zminimalizowania niekorzystnych wpływów na środowisko naturalne jego produkcji i utylizacji.

The implementation of clean coal technologies and the elaboration of the new solutions in the scope of coal production and utilisation are essential for minimising of their impacts on the natural environment and the climate changes. The competitive and environmentally friendly coal production and utilisation become simultaneously the important element of energy security in Poland and for European Union as well. The image of the coal in European Union, and especially in Poland - the country where energy production is mainly coal dependent, was not most favourable so far. In the paper the concepts of coal image changing in Poland are outlined, taking into consideration the coal role in energy mix and the needs of minimising of coal production and utilisation impacts upon environment.

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.

The paper presents the cleaner production goals and definitions, the source reduction as the most valuable pollution prevention method and two case studies of the cleaner production implementation. The implementation of the cleaner production technologies offers a chance to realize the concept of the sustainability development. To realize the sustainability development we need to achieve a consensual agreement for the protection of the environment which has been proposed by The Natural Step Theory TNS. There are two suggested ways of the production systems transformation using pollution prevention. The first one is the eco-efficiency, the second one - the system changes. This leads to the concept of the coefficient ,,10", one of the basic ideas of the sustainability development. It could be assumed that in the 21st century there will be observed a few jump-like system renewals resulting from a long-term research on the time scale every 20 years. These will lead to new fundamental societal and economic ecosystems.
