Objective The MIZDRA 2.0 project is to develop a new rational beam management technology in the tanning industry, in line with the idea of circular management and waste management hierarchy to (1) solve the waste problem, (2) obtain measurable economic benefits through (2a) savings and (2b) new products. The project will result in a pilot drying and pyrolysis installation at the BADER headquarters and a number of individual technologies with commercial potential.

SUMMARY

The aim of the MIZDRA 2.0 project is to develop in cooperation with three scientific units (Institute of Flow Flow Machine Robert Szewalski PAS – leader, Institute of Technology and Natural Sciences Poznań and Wrocław University of Technology, Faculty of Chemistry) rational wood management technologies in the tanning industry, in line with the circular economy and waste management hierarchy, to address the real problem of the accumulation of significant amounts of waste that can be processed using the company’s example BADER Polska Sp. z o.o. – industrial partner. The project will first develop biological processing methods for midra, resulting in the following products: collagen hydrolyzate, fat, biogas, fermentation, purified fermentation, organic and mineral-organic fertilisers. In the second place thermal methods will allow to obtain products such as: briquette enriched with recovered fat, pellets, biocarbons (from combustion), biocarbons (from pyrolysis), mineral fertilisers. The development will result in a pilot drying and pyrolysis installation at the BADER headquarters. The results will be achieved through the following work, where a closely cooperating consortium will demonstrate high complementarity and synergy between the following tasks.

Step 1 Test of conditions and preparation of raw material

Step 2 Recovery test for bio-products from midra

Step 3 Development of briquette and purification technologies for post-production residues

Step 4 Combustion and production of alternative active coals and fertilisers

Step 5 Development of drying technology and Mist pyrolysis

Stage 6 Pilot, modular installation for midra pyrolysis and real scale tests

Pre-implementation phase.

ABSTRACT

The goal of the MIZDRA 2.0 project is to develop, in cooperation with three scientific units (The Robert Szewalski Institute of Fluid-Flow Machinery, Polish Academy of Sciences - leader, Institute of Technology and Life Sciences – Poznań branch, Wroclaw University of Technology), rational waste management scripts to sell the real-case problem, where significant amounts of industrial bovine waste from Leather processing industry are produced at BASER Polska LtD. – industrial partner. Through the project, first the biological methods will be developed, results in the following products: collagen hydrolyzate, fat, biogas, digestate, purified digestate, fertilizers. In the second stage, thermal methods will allow to obtain such products as: briquette integrated with recovered fat, pellets, biochar (from communication), biochar (from pyrolisis), mineral fertilizers. As a result of development works, the pilot driving and pyrrosis installation at the BADER headsquarters will be developed. Above mentioned results will be carried out via various practices, where the cooperative consortium of partners provides the highest completion and synergy between progressing tasks.

Stage 1 Examination of the conditions and preparation of the raw material

Stage 2 Investigation of recovery of bioproducts from bovine shavings,

Stage 3 Development of briquetting technology and decontamination of processed biogas digestate,

Stage 4 Investigation of occupation and production of alternative activated carbons and fertilizers

Stage 5 Development of Drying Technology and Pyrolisis of the bovine shavings,

Stage 6 Pilot, modular plant for bovine shavings pyrolysis and real-scale testing

Pre-implementation phase.
