“…Ada beberapa metode mengubah biomassa menjadi energi seperti pembakaran langsung (Gebreegziabher et al, 2014), gasifikasi atau pirolisis (Basu, 2010), pencernaan an-aerobik (Beegle & Borole, 2018), hidrolisis (Quintero-Ramirez, 2014), hidrogenasi atau fermentasi (Abdullah, Bawadi;Muhammad, Syed Anuar Faua Ad Syed;Mahmood, 2012) dan pembuatan briket (Hwangdee et al, 2021). Pada umumnya yang digunakan sebagai bahan bakar adalah biomassa yang nilai ekonomisnya rendah atau merupakan limbah setelah diambil produk primernya.…”

Cadangan batubara di Indonesia diperkirakan sekitar 26 miliar ton dan masih akan menjadi energi primer sampai dengan tahun 2050, hal ini membuat pemanfaatan batubara menjadi energi bersih menjadi pekerjaan yang mendesak. Salah satu pemanfaatan batubara tersebut adalah dengan gasifikasi batubara. Dari hasil gasifikasi batubara, didapatkan suatu produk samping yaitu char. Dalam karakterisasi char ini didapatkan bahwa char mengalami peningkatan nilai fixed carbon dan GCV serta penurunan kadar sulfur yang signifikan. Hal ini, menjadikan char berpotensi menjadi bahan baku bahan bakar padat yang ramah lingkungan (briket). Penambahan biomassa berupa arang tempurung kelapa diharapkan dapat meningkatkan nilai kalor dan memungkinkan terjadinya penyalaan dari suhu rendah yang kemudian bisa menghemat waktu dan energi yang dibutuhkan untuk penyulutan briket, serta mempertahankan laju pembakaran. Karena itu sebagai studi awal, diperlukan studi kepustakaan dari penelitian sebelumnya sebagai dasar hipotesa awal dari penambahan arang tempurung kelapa dalam pembuatan briket dengan bahan baku utama char hasil gasifikasi batubara

“…The global price instability of these fuels has also created economic setbacks to some oil-dependent nations in the recent years with challenges expected to continue in the years to come [19][20][21]. Among the alternative sources of fuel and material for the petrochemical industry, biomass has significant potential to become more widely used in the near future due to numerous its advantages [22][23][24]. Significantly reducing humanity's dependence on fossil fuels as energy sources for industrial, residential and agricultural applications is a critical issue.…”

Purpose With its substantial CO2eq emissions, the agricultural sector is a significant greenhouse gas (GHG) emitter. Animal manure alone contributes 16% of the total agricultural emissions. With a rapidly increasing demand for animal-based protein, animal wastes are expected to rise if sustainable manure management practices are not implemented. Manures have the potential to be treated to generate valuable products (biofertiliser and biocrude) or feedstock for energy production. Thermochemical conversion technologies such as pyrolysis, combustion, supercritical gasification (SCWG), etc., have demonstrated their potential in manure management and valorisation. This study provides a broader overview of these technologies and envisages future manure valorisation trends. Methods The paper presents a state-of-the-art review of manure valorisation. Characterisation of manure, modelling and optimisation of thermochemical conversion technologies along with life cycle anaalysis (LCA) are also reviewed. Results The literature review highlighted that the thermochemical conversion technologies can generate bio-oils, syngas, H2, biofuels, heat, and biochar as carbon-free fertiliser. The reported calorific value of the produced bio-oil was in the range of 26 MJ/kg to 32 MJ/kg. However, thermochemical conversion technologies are yet to be commercialised. The major challenges associated with the scale-up of manure derived feedstocks are relatively high moisture and ash content, lower calorific value and higher concentration of impurities (N, Cl, and S). LCA studies conclude that gasification presents a sustainable option for manure valorisation as it is economical with modest environmental threats. Significance of Study This review briefly states the current challenges faced in manure management and presents the case for a sustainable valorisation of animal manures using thermochemical technologies. The economic, environmental and societal advantages of these technologies are presented in order to promote the scientific and industrial development of the subject in the academic and research community. Conclusions Thermochemical conversion technologies are promising for manure valorisation for energy and nutrient recovery. However, their commercialisation viability needs wide-ranging evaluations such as techno-economics, life-cycle analysis, technology take-up and identification of stakeholders. There should be clear-cut policies to support such technologies. It should be advocated amongst communities and industries, which necessitates marketing by the governments to secure a clean energy future for the planet. Graphical Abstract
