Energy primarily comes from fossil fuels, which leads to environmental deterioration through increased carbon dioxide load and other greenhouse gases in the atmosphere. Renewable energy is a cheap alternative, biomass, like municipal solid wastes (MSWs), can be suitably used for production. This paper reviews impact of variations MSW composition on its physical, chemical, lignocellulosic properties. It further illustrates how these properties affect torrefaction products. was observed that refer either combination different waste types or independent wastes; hence, there no standard MSW. The are responsible fluctuating These properties, along with process parameters, simultaneously torrefied product, whereas influence biochar yield, physical chemical calorific value ash content. Torrefying containing low moisture content yields high value. Methods improve have not been studied. Research needed assess possibility improving by enhancing lignin percentages, possibly blending A guide best blend combinations ratios required. Also, it crucial study optimal parameters.

Most organic waste from food production is still not used for energy production. From the perspective of production, one option to valorise properties waste. The fruit juice industry growing rapidly and generates large amounts One main wastes in processing peach pits apple peels. aim this study was analyse influence torrefaction temperature on waste, namely peels, pea shells, order improve their value determine potential further use valorisation as a renewable source. different temperatures heating (HHV), mass yield (MY) (EY) better understand behavior thermal individual selected samples. process carried out at 250 °C, 350 °C 450 °C. obtained biomass compared with dried biomass. For HHV after (28 kJ/kg), MY decreased by (66–34%), while EY fell (97–83%). Peach pits, despite higher (18 achieved low (38–89%) (59–99%), which reduces efficiency biochar Pea peels had (82–97%) lower (11 but high ash content limits wider use. results confirm that, increasing temperature, all biomasses decrease, consequence degradation hemicellulose cellulose loss volatile compounds. In most cases, improved resistance moisture adsorption, related that causes structural changes. showed hydrophobic Temperature seen have great impact efficiency. Apple generally highest yield.

The excessive use of Kesambi (Schleichera oleosa) tree stems threatens the sustainability plants since it takes several decades for them to regenerate new stems. This research aims determine characteristics torrefied pruning. used reactor has a diameter 400 mm. An iron basket is positioned 100 mm above base, holding material within an aluminum cylinder. temperature maintained at 300°C using K-type thermocouple sensor. A heater placed near base and covered. semi-charcoal biomass product are identified, including mass yield, water absorption capacity, moisture content (D3173, 2013); ash (ASTM D1102-84. Standard Test Method Ash in Wood, volatile matter (%) (ASTMD3175, 2011); fixed carbon (ASTM, 2013). color leaves pruned changes from brown black as residence time increases. results pruning different torrefaction times indicate decrease yield with increase time, lowest observed 20 minutes. capacity found be between 0.65% 0.675%, or less than 1% higher heating value (HHV) prediction 29.0750 MJ/kg.Keywords: Kesambi, Pruning, Residence, Time, Torrefaction

Permintaan energi yang meningkat menyebabkan penurunan ketersediaan bahan bakar fosil. Biomassa dari limbah kelapa sawit yaitu tandan kosong sawit, dapat digunakan menjadi alternatif bakar. Proses torefaksi mengubah biomassa biopelet ramah lingkungan dan bernilai tambah tinggi. Dalam penelitian ini, kalibrasi sensor termocouple tipe K dilakukan dengan Arduino Uno pengujian alat otomatis pelet Tandan Kosong Kelapa Sawit (TKKS). Penelitian ini bertujuan untuk mengembangkan sistem kendali pelet. Perancangan menggunakan mikrokontroler sumber kompor gas.
