Abstract

Waste is a product of society and one of the biggest challenges for future generations is to understand how to sustainably dispose of large amounts of waste. The main objective of this study was to determine the possibility and conditions of the decentralized combustion of non-hazardous municipal waste. The analysis of the combustion properties of a mixture of wood chips and 20–30% of municipal solid waste showed an improvement in the operating parameters of the combustion process. Analysis also confirmed that the co-combustion of dirty fuels and biomass reduced the risk of releasing minerals and heavy metals from fuel into the natural environment. Approximately 55% of the heavy metals passed into the ash. The analysis of municipal solid waste and fuel mixtures containing municipal solid waste for polycyclic aromatic hydrocarbons showed the risk of increasing polycyclic aromatic hydrocarbon concentrations in flue gases.

Highlights

In recent years, two important issues have been actively discussed in Slovakia and around the world
This study focuses primarily on the possibilities of sharing energy from municipal solid waste (MSW) and biomass
An addition of 20–30% of MSW to the fuel mixture showed an improvement in the operating parameters of the combustion process

Summary

Introduction

Two important issues have been actively discussed in Slovakia and around the world. The first is the protection of the air and reduction of negative effects on the environment from different types of fuels. An integral part of these discussions and ongoing research is the European Parliament’s call for pollution reduction without loss of effectiveness. Directive 2009/28/EC of the European Parliament and of the Council about the promotion of the use of energy from renewable sources refers to the use of energy efficient technologies [1]. Waste is an inevitable product of society and one of the biggest challenges for future generations is to understand how to sustainably dispose of large amounts of waste. One approach is to minimize the amount of waste produced and recycle larger fractions of waste material
