Much research has been done throughout the world to determine the economic and ecological profitability of waste utilization as a substitution for raw materials. Unfortunately, Poland has no sufficient solutions in this field. The deficiency of solutions impedes the work of groups of specialists in various fields involved with the rational planning of recycling. This research seeks to offer a simple unified framework to study the key economic features of the use of waste as substitute for nonrenewable resources in production in Poland and other countries. The purpose of this paper is to develop a model to obtain some key insights about the cost-effectiveness and define certain parameters which determine the effectiveness of production plants dedicated for processing waste into useful products. A plant's productive possibilities can be described by the production function which is determined empirically. In this model, the emphasis is put on plant functioning and is dependent on the amount of work destined for the production in fixed units, technical maintenance costs of the work fixture in fixed units (e.g. machines', cars' operating costs etc.), and the amount of modified waste. In order to calculate these costs, we need to consider the issue of precise measuring the overhead costs in order to maximize profitability of this kind of measures allocation so that the profit will be the highest. The task of measuring overhead (costs) comes down to finding the maximum of the production function. This research presents the mathematical model and provides some key insights about the profitability of the plants dedicated for processing waste into secondary materials. In this research, we also determined the maximum of the profit function and assess when the recycling plant will bring the profit and when it is the highest.
W artykule przedstawiono zarys obecnej sytuacji sieci recyklingu samochodów wycofanych z użytku w kraju. Stanowi on podstawę do rozważań na temat możliwych kierunków zmian w sieci recyklingu w kontekście przystąpienia Polski do Unii Europejskiej. Na wstępie przedstawiono skalę tego problemu w Polsce na tle krajów członkowskich Unii. W dalszej części szczegółowo opisano obecna sieć recyklingu funkcjonującą w naszym kraju ze szczególnym uwzględnieniem stacji demontażu stanowiących podstawowe ogniwo sieci recyklingu. Następnie przybliżono obowiązujące przepisy prawne oraz wymagania przepisów unijnych wyznaczające ramy ewolucji sytuacji w przyszłości. Określono również inne czynniki, oprócz administracyjno-prawnych, które będą odgrywały najważniejszą role w kształtowaniu sieci recyklingu.

The purpose of this article is to attempt to describe the existing national system for the recovery and recycling of end-of-life vehicles and set up the background to discuss the future development of the system according to the European Union law. It presents the main problems that are encountered in end-of-life vehicles treatment process in Poland, particularly, the scope of the issue and the treatment facilities network. The important part of the article concerns domestic law in force and the objectives set out in the 2GOO/53/EC Directive that shall be adopted by all Member States of the European Union. Other main factors that might influence the recycling system, except the legal ones, were also identified.
