“…Gasification of tannery waste is a rather poorly described technique for utilization in the literature. Due to the low potential of the syngas obtained in the gasification process of tannery waste, it is rather the first stage of combustion and not the actual gasification [54].…”

“…The property of the fuel that significantly hinders gasification is the low heat conduction coefficient through the tannery waste bed. In the case of co-current gasification, the heat is transferred to the fresh fuel only by conduction and, in the case of low thermal conductivity, co-current gasification is very unstable and difficult to operate [54]. For countercurrent gasification, convection is a mechanism of heat conduction, apart from conduction itself, thanks to which the gasification of tannery waste in countercurrent reactors is possible.…”

The tanning industry generates significant amounts of solid waste and post-production wastewater, which should be managed in accordance with the principles of the circular economy. Waste is generated at various technological stages of production. This comprises mainly solid waste and leachate. A comprehensive solution to the problem of disposal of this waste is very important from economic and environmental points of view. This work presents research for a technological production line designed for the comprehensive processing of post-production residues. In the present paper, the authors present an analysis related to the possibility of processing leather flesh side (mizdra) as a substrate for methane fermentation. The study showed an increased biogas production from solid waste after enzymatic hydrolysis up to 248 Nm3/Mg. Preliminary research on the system designed for pre-treatment of sewage from the technological line is also presented. The study showed a COD reduction of more than 30%. The possibility of energy management of the solid fraction directly from the processes carried out is demonstrated.

Penelitian ini bertujuan untuk menganalisis pengaruh penggunaan isolator terhadap kinerja tungku gasifikasi tipe downdraft . Tiga bahan isolator yang digunakan yaitu serbuk batu bata, serbuk batu padas dan pasir. Parameter utama yang digunakan sebagai tolok ukur kinerja tungku gasifikasi yaitu suhu pembakaran dan durasi nyala api yang dihasilkan dari bahan bakar biomassa . Biomassa yang digunakan dalam penelitian ini adalah sekam padi. Penelitian dilakukan dengan dua tahap, tahap pertama dilakukan pengujian kinerja tungku gasifikasi tanpa menggunakan isolator. Tahap kedua yaitu dilakukan pengujian dengan menggunakan isolator yang dipasang pada dinding tungku gasifikasi. Hasil pengujian tungku tanpa isolator didapatkan temperatur rata-rata nyala api sebesar 272 °C dan nyala efektif api selama 5 3 menit . Pengujian dengan penambahan isolator didapatkan suhu rata-rata nyala api dengan bahan serbuk batu bata sebesar 506°C dengan isolator suhu 102°C dan nyala efektif api selama 54 menit. Untuk serbuk batu padas suhu rata-rata nyala api sebesar 484°C dengan isolator suhu 134°C dan nyala efektif api selama 53 menit. Sedangkan isolator pasir temperature rata-rata nyala api sebesar 466°C, temperature isolator 146°C dan nyala efektif api selama 52 menit. Berdasarkan hasil penelitian yang dilakukan maka kinerja tungku gasifikasi dengan menggunakan isolator meningkat dibandingkan tungku tanpa isolator . I solator serbuk batu bata meningkat kan kinerja tungku gasifikasi sebesar 90,2% sedangkan untuk serbuk batu padas dan pasir masing-masing sebesar 83,2% dan 77,6%. Hasil ini menunjukkan bahwa serbuk batu bata merupakan isolator yang paling optimal dibandingkan dengan serbuk batu padas dan pasir.
