Fuels from Waste as Renewable Energy in Distributed Generation on the Example of the ORC System

Abstract

The article compares the energetic qualities of fuels from waste with hard coal. A cogeneration system has been modeled based on the organic Rankine cycle (ORC) powered by the investigated fuels in order to identify possibilities as well as problems in use of fuels from waste in an exemplary cogeneration unit in distributed generation. The emission of thermal transition of the investigated fuels has been calculated on the basis of their energetic use in order to determine the aggregate impact on the environment, people’s health and the ecosystem. In order to conduct the research, Ebsilon Professional and SIMAPro software were used. The article demonstrated the energetic and ecological validity of the use of fuels form waste in small-scale combined heat and power (CHP). The energetic potential and influence on the environment, people’s health and the ecosystem depends on the quality of fuel, but the strict regulations for generating fuels from waste and the flexibility in forming them, allow for a product which is more beneficial economically and ecologically than hard coal.

Influence of Valorization of Sewage Sludge on Energy Consumption in the Drying Process

“…This is supported by the limitation of the use of conventional energy sources and the limitation of landfilling. Guidelines for this can be found in the Directive of the European Parliament and of the Council 2018/850 from 30 May 2018 [50] amending Directive 1999/31/EC concerning the storage of waste [51].…”

Removal of Pollutants from Secondary Waste from an Incineration Plant: The Review of Methods

“…Alkaline pre-treated waste should always be tested, because of the heterogeneity of the composition. Improving secondary waste quality is in line with the principles of sustainable development and a circular economy [59][60][61].…”
