Abstract

A model of the meat waste management The European Union produces about 18 million tons of waste from meat industry per year. The real danger of the BSE disease caused a necessity of looking for a new alternative solution of meat waste management. The proposed solution of meat industry waste management would create meat production waste free with the use of the cleaner production method. Cleaner production includes: pollution prevention, reduction of the source, recovery of materials and energy (for example: the recovery of blood plasma and protein hydrolisate from bone sludge) and their recycling. The thermal processing of meat industrial waste (bone sludge, meat-bone meal and odour) is anticipated, too. Ashes from meat calcining have the phosphorus content close to its concentration, of the typical phosphoric raw materials. That confirmed the possibility of using such ashes as the substitute of phosphoric raw materials. The target model of waste free meat waste management included the results of the implemented and current research.

Highlights

Europe generates of about 18mln t/year of meat wastes that should be utilized, according to the appropriate UE directive
It is important that meat waste processing resulted in bio fuel that substitutes the conventional energy source1 – 3
Fat could be recovered from meat waste in the abovementioned processes and in the production of meat bone meal from animal waste3, 26

Summary

INTRODUCTION

Europe generates of about 18mln t/year of meat wastes that should be utilized, according to the appropriate UE directive. The animal wastes processing into the meat-bone meal still remains the basic methods of their utilization, due to a very large quantity of meat factories existing in Poland and in Europe. The thermal processing of meat and bone is developed This resulted in the production of the ash with the properties allowing to use it for phosphate compounds manufacturing as the substitute of natural phosphoric raw material – . The quantities of waste obtained in particular meat factories are diversified, depending on the raw materials used, technology level, equipment and many others factors, especially production capacity. Variant II (Table 2) proposes thermal utilisation of meat bone meal and the use of the produced ash as raw material in the phosphoric acid production. Are presented the implemented and developed solutions of meat waste and the by-products management

Utilisation of animal blood

Production of proteins hydrolysate and gelatine

Recovery of fat from meat and bone waste
