Combustion behavior of poultry and plastics waste in as bench scale combustor

Abstract

Nowadays, combustion municipal solid waste (MSW) with energy recovery is the most popular method to decrease the usage of landfill. It is another alternative to overcome landfill site scarcity beside material reuse and recycling. Recently, combustion poultry for the purpose of energy recovery was the best method to dispose of animal by product such as poultry. To substitute coal as fuel, MSW and poultry were compacted into pellet to identify fuel characteristics from this fuel. The purpose of this study is to study the effect of poultry on fuel characteristics of MSW. In this study, poultry and MSW will be mixed with five types of mixtures on a weight basis (0 %, 25 %, 35 %, 50%, 70% of poultry). Both the poultry and MSW were crushed to a uniform powder. Poultry were mixed with MSW and made into pellets using hand held pelletizer. These pellets size were 27 mm in diameter and 15 mm in length. The pellet weighed was roughly 5 g. All the mixtures were pelleted to a compaction ratio 1:5. The pellet was sent to the furnace to determine ash content and volatile matter. Calorific value was determined using bomb calorimeter. Volatile matter, residual moisture content and calorific value increased with increasing percentage of poultry in pellet fuel. Ash content decreased with increasing percentage of poultry in pellet fuel. Therefore, inclusion poultry to MSW pellet fuel enhanced properties of fuel. 35 wt % is the minimum percentage of poultry to MSW pellet fuel produced fuel with good properties.
