“…High-temperature pyrolysis (Sethuraman et al, 2013, 2014; Simioni et al, 2014; Wang et al, 2014) is a direct method, in which the LSWs are heated up to high temperatures in an inert atmosphere. Subsequently, they decompose and are converted into some gaseous, liquid and solid products, such as pyrolysis gas, fuel oil and solid residue.…”

“…Several novel high-temperature pyrolysis routes are recently proposed. Sethuraman et al (2013) proposed a pyrolysis gasification process to recover fuels and value added byproducts from the CTSWs. It was found that chromium(III) was not converted into carcinogenic chromium(VI) during this pyrolysis gasification process described.…”

Leather making is one of the most widespread industries in the world. The production of leather goods generates different types of solid wastes and wastewater. These wastes will pollute the environment and threat the health of human beings if they are not well treated. Consequently, the treatment of pollution caused by the wastes from leather tanning is really important. In comparison with the disposal of leather wastewater, the treatment of leather solid wastes is more intractable. Hence, the treatment of leather solid wastes needs more innovations. To keep up with the rapid development of the modern leather industry, various innovative techniques have been newly developed. In this mini-review article, the major achievements in the treatment of leather solid wastes are highlighted. Emphasis will be placed on the treatment of chromium-tanned solid wastes; some new approaches are also discussed. We hope that this mini-review can provide some valuable information to promote the broad understanding and effective treatment of leather solid wastes in the leather industry.

“…There are also studies related to pyrolysis of tannery wastes [12]. On the other hand, Abdulrazak, et al [13] used activated carbon from Moringa Oleifera pods for the treatment of tannery wastewater and they prepared the activated carbons by carbonization in nitrogen at 900 °C followed by activation at 825 °C in carbon dioxide of chromium-tanned leather. Masilamani, et al [14] were able to develop biodegradable packing materials from gelatin that extracted from Tannery solid waste.…”

The vast quantity of waste generated from industries is one of the serious outcomes of unplanned development, resulting into quantum of hazardous organic and inorganic waste generating daily. Proper waste management is a challenging issue that must be addressed adequately. This is, therefore, carried out with a view of assessing the energy and combustion quality of tannery solid waste with a view of converting them into briquettes for cooking, heating and small home industries and reducing the menace caused by tannery waste disposal. The results of the experiments showed that the combustion rate ranged between 0.171 and 0.217 g/min, the boiling time ranged between 27.78 to 34.11 minutes, the ignition time was found between 14.2 to 17.4 minutes. The durability test and humidity resistance test showed that the briquettes have durability ranged between 92.12 and 95.04 while the humidity resistance was between 95.34 and 97.95. The carbon content ranged between 40.79 and 45.15%. Other results showed that the fixed carbon ranged between 89.93 and 95.46%, volatile matter 1.61 to 4.56% and the calorific values were found between 18.03 and 21.86 MJ/kg. The fleshing has better quality than the other three wastes studied. AbstractPotensi Energi dari Briket yang Dihasilkan dari Limbah Padat Penyamakan Kulit Binatang Ternak. Jumlah limbah yang dihasilkan dari industri merupakan salah satu masalah serius dari perkembangan yang tidak direncanakan, yang mengakibatkan besarnya jumlah sampah organik dan anorganik yang tertimbun setiap hari. Pengelolaan limbah yang tepat merupakan tantangan yang harus ditangani secara benar. Pengelolaan ini dilakukan dengan berpandangan bahwa energi dan pembakaran dari limbah padat penyamakan kulit dapat diubah menjadi briket untuk memasak, memanaskan dan membantu industri rumahan kecil serta mengurangi ancaman yang diakibatkan oleh pembuangan limbah industri penyamakan kulit. Hasil percobaan menunjukkan bahwa laju pembakaran berkisar antara 0,171 dan 0,217 g/menit, waktu didih sekitar 27,78 sampai 34,11 menit, waktu pengapian sekitar 14,2 sampai 17,4 menit. Uji ketahanan dan uji resistansi kelembaban menunjukkan bahwa briket memiliki daya tahan sekitar 92,12 dan 95,04 sedangkan nilai resistansi kelembapan antara 95,34 dan 97,95. Kandungan karbon berkisar antara 40,79 dan 45,15%. Hasil lainnya menunjukkan bahwa karbon tetap berkisar antara 89,93 dan 95,46%, material volatil 1,61 sampai 4,56% dan nilai kalor ditemukan antara 18,03 dan 21,86 MJ/kg. Limbah dari tahap fleshing memiliki kualitas yang lebih baik daripada tiga limbah lainnya yang diuji.
