A Comparison of two Biological Treatment Processes for Residual Waste Management
The paper presents a technology comparison of MBT Anaerobic Digestion and MBT biodrying for treatment of residual municipal waste.
Specifically the paper enables a strategic decision to be made on the optimal deliverable residual waste management solution for municipal waste contracts where the generation of an SRF, either as an element of the overall solution or as a contract output is required. Both technologies have been proposed as precursors for SRF production in recent UK municipal waste management contracts. The most important factors in the evaluation of municipal waste tenders are project cost followed by landfill diversion and deliverability. The analysis indicates that the AD solution offers the potential to achieve the highest landfill diversion performance however they tend to exhibit higher lifecycle project costs than biodrying solutions. Furthermore AD solutions suffer against deliverability primarily because of the lower calorific content of the SRF and the implications that this may have on securing long term markets. MBT biodrying solutions do not exhibit the highest landfill diversion performance and the quality of recyclates can be problematic due to contamination issues. However where a concept can be developed based on only metals and dense plastics recycling and where the fines fraction can be incorporated with the SRF, then MBT biodrying would appear to offer a deliverable solution exhibiting a competitive cost and offering a high level of deliverability. The paper concludes with the Author’s overview of the preferred technology against a given range of parameters.

Hungarian municipal solid wastes (MSW) management has developed tremendously over the past 15 years. More than 3,000 landfills and dumps had been closed, just to mention one improvement. However, still, lots of work is necessary to accomplish the EU’s ambitious aim of decreasing landfilling and increasing recycling and composting.

A mechanical biological treatment (MBT) process for municipal solid waste (MSW), suitable for the boundary conditions of newly industrialized countries (NIC), was developed and tested in Thailand. The main purpose was to make the process simple, robust and economic. The process focuses on the production of refuse-derived fuel (RDF) and a high biogas yield. The so-called BIOBUNK pilot plant consists of a shredder as mechanical stage and an aerobic mixed reactor as biological stage.
