Energy Potentials of Briquette Produced from Tannery Solid Waste

Abstract

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.

Development of a Multiple-Piston Hydraulic Briquetting Press HBP and Characterization of Newsprint Briquettes Produced

“…The ability of each fuel to generate heat was predicted by the atomic ratios (H/C and O/C) as assessed in Table 6. These values were lower than those produced by Nhuchhen et al 5 and within the same range 7,71,72 .…”

Briquette production from sugar cane bagasse and its potential as clean source of energy

“…Presence of ash decreases the heating value (Onukak et al, 2017) so that the quality briquettes have low ash contents (Carnaje et al, 2018). The tolerance level for the ash content in a fuel is below 4% (Oyelaran et al, 2017). The ash content of bagasse briquette (Clay as a binder 20:80) and bagasse briquette (molasses as a binder 10:90) obtained from this study is 4 and 3%, respectively.…”

Production of Low Emission Briquettes from Faecal Sludge as an Alternative Source of Cooking Energy

“…Briquette's proximate analysis includes volatile matter (%), moisture content (%), bound carbon (%) and ash content (%). According to The tolerance limit for the briquette's moisture content is between 8 and 12%, depending on the type of feed (Oyelaran et al, 2017). This study shows that the moisture content of both briquettes was within tolerance (Figure 7).…”
