“…With significant emissions of methane from concentrated sources, such as landfill gas, some solutions are proposed to accelerate the oxidation of such methane by its collecting and oxidizing to generate bioenergy [24]. Another way to minimize methane emissions from landfills is to oxidize it in a bioactive cover layer [25].…”

Biofuel such as linseed oil has an energy potential of 48.8 MJ/kg, which is much lower than fossil diesel fuel 57.14 MJ/kg. Existing biofuels need to increase the energy potential for use in traditional engines. Moreover, biofuel production demands cheap feedstock, for example, sawdust. The present paper shows that the technology to synthesize high-energy liquid vehicle fuels with a gross calorific value up to 53.6 MJ/kg from renewable sources of plant origin is possible. Slow pyrolysis was used to produce high-energy biofuel from sawdust and linseed oil. The proposed approach will allow not only to preserve the existing high-tech energy sources of high unit capacity based on the combustion of liquid fuels, but also to make the transition to reducing the carbon footprint and, in the future, to carbon neutrality by replacing fossil carbon of liquid hydrocarbon fuels with the carbon produced from biomass.

“…selain gasgas seperti diatas, gas penyusun lainnya yang terkandung dalam biogas adalah gas hidrogen sulfida H2S sebesar 790 ppm [5]. Salah satu gas yang terkandung pada biogas yaitu gas metana CH4 yang dapat memberikan efek Green House Gases (GHG), mampu menyebabkan global warming sebesar 25 kali lipat dari gas karbon dioksida CO2, dan merupakan sumber antropogenik terbesar setelah tambang batubara [6]. Disamping itu, gas hidrogen sulfida H2S yang terkandung dalam biogas mampu memberikan pengaruh bau yang tidak baik ke lingkungan, beracun dan bersifat korosif yang dapat merusak biogas engine [7].…”

Nilai kalor yang dimiliki oleh biogas sangat mempengaruhi lamanya waktu proses pembakaran. Beberapa penelitian telah dilakukan untuk meningkatkan nilai kalor yaitu dengan menurunkan kadar zat pengotor yang terkandung bersama biogas. Dalam penelitian ini dilakukan upaya peningkatan nilai kalor biogas dengan menggunakan steel wool sebagai adsorben dengan variasi massa steel wool (500 gram dan 600 gram) dan variasi laju aliran biogas (1 lpm, 2 lpm, dan 3 lpm). Peningkatan nilai kalor biogas sebelum dan sesudah pemurnian ditentukan dengan water heating test. Hasil penelitian menunjukan peningkatan nilai kalor diperoleh pada filter dengan massa adsorben 600 gr dan laju aliran biogas 1 lpm, dimana nilai kalor meningkat sebesar 36.19%. Sedangkan filter dengan 500 gr steel wool adsroben dan laju aliran biogas 3 lpm, menghasilkan peningkatan nilai kalor terendah yaitu sebesar 4.46%. Hasil eksperimen menunjukan peningkatan nilai kalor semakin tinggi jika laju aliran biogas makin rendah melalui kolom adsorben dengan massa steel wool yang semakin tinggi.

“…The landfill area also gives the big potential for GMT applications. According to Kashyap et al [73], India produces 210 million tonnes of municipal solid waste with 50% organic components. Landfills are mostly open and produced landfill gas is not utilised in any way; only produce methane gas that increases the greenhouse effect and is harmful to our environment.…”
