Abstract

Flexibility of mechanical biological treatment plants

Highlights

  • Municipal Solid Waste (MSW) is one of major concerns of modern civilization

  • Mechanical Biological Treatment (MBT) is a set of technological operations of waste treatment which can result in various final products and is in accordance with the aims of the waste hierarchy

  • Products of MBT vary from Refuse Derived Fuel (RDF)/Solid Recovered Fuel (SRF) to the stable organic components that can be disposed on landfills or, under certain circumstances, can be used as soil conditioners (CLO)

Summary

Introduction

Municipal Solid Waste (MSW) is one of major concerns of modern civilization. Despite huge progress in various technologies of MSW treatment the problem of waste is far from being solved. Having in mind very complicated nonuniform composition of MSW all waste treatment technologies are dedicated to the same goal of best possible reuse of each ingredient of MSW establishing thesis that waste should not be destroyed but be source of valuable materials and energy. All technologies developed and in use are practically between these two extreme points, including Mechanical Biological Treatment (MBT) of MSW. There are several aims of MBT regarding waste hierarchy and scopes of the EU Landfill Directive (1999/31/EC) [2]: - pre-treatment of waste going to landfill i.e. decreasing the volume of waste disposed to landfill, - diversion of biodegradable municipal solid waste (BMW) from non-biodegradable MSW through mechanical sorting ensuring recycling and/or energy recovery through producing refuse derived fuel (RDF), Tehnički vjesnik 23, 6(2016), 1871-1877. In Europe were built many facilities for the treatment of MSW based on MBT [3÷8]
