Waste management in the meat processing industry: conversion of paunch and DAF sludge into solid fuel

Hamawand, Ihsan and Pittaway, Pam and Lewis, Larry and Chakrabarty, Sayan and Caldwell, Justin and Eberhard, Jochen and Chakraborty, Arpita (2017) Waste management in the meat processing industry: conversion of paunch and DAF sludge into solid fuel.

This article addresses the novel dewatering process of immersion-frying of paunch and dissolved air
flotation (DAF) sludge to produce high energy pellets. Literature have been analysed to address the feasibility
of replacing conventional boiler fuel at meat processing facilities with high energy paunch-DAF
sludge pellets (capsules). The value proposition of pelleting and frying this mixture into energy pellets
is based on a Cost-Benefit Analysis (CBA). The CBA is based on information derived from the literature
and consultation with the Australian Meat Processing Industry.
The calorific properties of a mixture of paunch cake solids and DAF sludge were predicted from literature
and industry consultation to validate the product. This study shows that the concept of pelletizing
and frying paunch is economically feasible. The complete frying and dewatering of the paunch and DAF
sludge mixture produces pellets with energy content per kilogram equivalent to coal. The estimated cost
of this new product is half the price of coal and the payback period is estimated to be between 1.8 and
3.2 years. Further research is required for proof of concept, and to identify the technical challenges associated with integrating this technology into existing meat processing plants
