Abstract
Coal combustion products can be considered as commercial products or waste depending on the quality of the coal, the combustion process, and the country’s legislation. The circular economy can create incentives for the implementation of new business models in large power plants in cooperation with coal mines and users of coal combustion products. This is particularly important in Poland, where coal still remains the main source of energy, employing over 80,000 workers. The objective of this study was to assess the readiness for change toward a circular economy and to identify challenges, barriers, and plans at seven large power plants. To do this, a final questionnaire was developed after checking environmental reporting, a CATI survey, and brainstorming between circular economy leaders from science, industry, and non-governmental organizations. The results indicate that even if the great economic and environmental potential of coal combustion products management are understood, all requirements connected with CO2 and air pollution have higher priorities. Policy shifts away from coal do not promote cooperation, but the higher acceptance of products from waste and more transparent data shows a large potential for changes toward a circular economy.
Highlights
The production volumes of coal combustion products (CCPs) are directly correlated with coal combustion in thermal power stations
In order to investigate the role of circular economy (CE) in LPP, we follow Gonenc and Scholten [22], who suggested that future studies should take into account corporate intentions and actions taken which are in line with such intentions
The set of terms under aspect 1 concerned the evaluation of the benefits/effects related to implementing CE in a coal power company (Figure 2)
Summary
The production volumes of coal combustion products (CCPs) are directly correlated with coal combustion in thermal power stations Their quality, depends on the mineral composition of the coal, combustion efficiency, type and fineness of the coal, time of storage of the minerals in the furnace/boiler, etc. Some of them i.e., pulverized fly ash, are a valuable waste residue used in concrete production [2]. They can pose serious threats to air, water, and soil; over the past two decades, research has been developing methods to combine both the quality of power generation, economic viability, environmental safety, quality, and the effective use of waste products [3].
