Impacts of Market and Legislation Changes on WTE Plant Operation

The feasibility of combined heat and power Waste to Energy plant in the conditions of implementation of the new legal framework for waste disposal and management, as well as new power market conditions, is investigated in this paper. As waste management and the need for sustainable energy supply are identified as core issues of sustainable development of regions, these two energy flows logically come together in the heat and power cogeneration facility by waste incineration. However, with the implementation of new legislation guidelines, quantity and characteristics of municipal solid waste changes, which has a great influence on the operation of this kind of systems. Because of this, feasibility Waste to Energy facilities may come in jeopardy with the development of waste management systems over the years. In this paper gradual compensation of decreasing municipal solid waste production by introducing new fuels such as woody biomass from the industry, agriculture and energy crops is investigated. Waste to Energy facility also needs to achieve profitability within the energy markets. Economic analysis shows that decrease in waste quantities can be compensated with woody biomass which can increase the feasibility of such projects. In the case when waste legislation goals are met by source separation, such compensation increases the profitability of the already profitable project. This can enable reduction of gate fees for same economic results. Further interventions in the waste management system (e.g. introduction of the mechanical-biological treatment facility) can further influence the profitability of these kinds of projects and make the viability of this project dependent on fuel compensation. The presented approach also is shown possible benefits in analysing the operation of Waste to Energy plants on electricity and heat markets.
