“…Assessment of the energy potential of the avocado seed by Perea-Moreno et al [6] shows that avocado stone has a higher High Heating Value (HHV) making it a viable source of energy. Reference [22] reports that avocado seed reached its ultimate biogas potential earlier than banana and potato peels. Avocado peels can work as substrates for biogas production.…”

Bioprocessing can help redeem the economic value for avocado (Persea americana) in Uganda. This study reviews the virgin potential of avocado bioprocessing in Uganda. Avocado consists of flesh, seed, and peel. The review indicates that the waste seed and peel are vital for development of high-value products. Both the edible part and waste (peel and seed) can be used for biogas production through a solid-state fermentation process. Biodiesel can be developed using avocado seed oil through a process called transesterification. Avocado oil is a better alternative for biodiesel production compared to waste cooking oil as it requires no further conversions processes for transforming fatty acids to esters. The starch-rich avocado seed is a suitable substrate for bioethanol, pigment and starch production. The high starch content places the avocado fruit as a potential: 1) raw material for the production of bioplastics; 2) substrate for bacterial culture media production as opposed to potatoes, cereals, and cassava that double as a staple food. Avocado seeds can also be used for the production of antioxidants relevant for preventing enzymatic browning, thereby increasing product shelf life. Despite the quick wins, there is a need for increased research, financing, personnel training and development of appropriate policies to spur the benefits and untapped potential of avocado bioprocessing in Uganda. The circular economy of avocado waste alone into high-value products could increase gains in the environment and stimulate industrial development, especially the cosmetic, food and pharmaceutical industries in Uganda.

“…In agriculture, AD has traditionally been applied to treat cattle and other livestock slurries, but these are low-value substrates in terms of energy content [3,4]. To improve the energy yield, a frequently applied strategy is co-digestion, where manure is combined with energy-rich biomass such as food waste or other types of organic wastes, including crop residues or biomass grown for this purpose, i.e., energy crops [5][6][7]. As bioenergy production from crop-based materials and residues becomes more widespread, there is a need for information on potential biogas and methane yields of such biomass types.…”

Estimating the Methane Potential of Energy Crops: An Overview on Types of Data Sources and Their Limitations

et al. 2021

As the anaerobic digestion of energy crops and crop residues becomes more widely applied for bioenergy production, planners and operators of biogas plants, and farmers who consider growing such crops, have a need for information on potential biogas and methane yields. A rich body of literature reports methane yields for a variety of such materials. These data have been obtained with different testing methods. This work elaborates an overview on the types of data source available and the methods that are commonly applied to determine the methane yield of an agricultural biomass, with a focus on European crops. Limitations regarding the transferability and generalisation of data are explored, and crop methane values presented across the literature are compared. Large variations were found for reported values, which can only partially be explained by the methods applied. Most notably, the intra-crop variation of methane yield (reported values for a single crop type) was higher than the inter-crop variation (variation between different crops). The pronounced differences in reported methane yields indicate that relying on results from individual assays of candidate materials is a high-risk approach for planning biogas operations, and the ranges of values such as those presented here are essential to provide a robust basis for estimation.

“…Organik kökenli atıklardan kontrollü şekilde biyogaz üreterek alternatif enerji miktarını artırmak gerekmektedir. Bu sebeple, büyükbaş, küçükbaş ve kanatlı hayvan atıklarının yanı sıra alglerden, peynir alt suyundan, dikenli incirden meyve atıklarından, kahve atıkları gibi atıklardan biyogaz üretilmektedir (Battista et al, 2016;Comino et al, 2009;Lanari & Franci, 1998;Montingelli et al, 2015;Quiroz et al, 2021;Spence et al, 2019;Thompson et al, 2021;Tsigkou et al, 2021). Tüm atıklardan uygun şartlarda biyogaz üretimi yapılmasıyla bunlardan kaynaklanan kötü görünüm, koku giderilerek, bulaşıcı hastalık risklerinin önüne geçilecek ve küresel ısınma azaltılarak hava kirliliğinin de önüne geçilir (Agency(EPA), 2021; Kalinichenko & Havrysh, 2019).…”

ÖzDünya nüfusunun artışı ve teknolojik gelişimler sebebiyle ortaya çıkan gıda ve enerji talebini karşılayabilmek için araştırmalar yoğun şekilde devam etmektedir. Enerji ihtiyacını giderebilmek için arz doğal gaz, kömür, petrol gibi fosil kaynaklı yakıtlardan ya da nükleer kaynaklardan sağlanmaktadır. Fosil kaynakların miktarının sınırlı olması ve oluşturduğu sera gazı etkisi sebebiyle alternatif enerji araştırmaların birçoğu biyodizel, biyogaz, rüzgâr, güneş enerjisi gibi yenilenebilir yakıtlar üzerinde yoğunlaşmıştır. Sera gazı etkisini oluşturan gazlar içerisinde karbondioksit ile birlikte metanojen bakterileri tarafından üretilen metan(bataklık-biyogaz) gazları önemli bir yer tutmaktadır. Uygulanabilirliği, sürdürülebilirliği, düşük üretim maliyeti, sera gazı oluşumunu azaltması ve süreç sonucu elde edilen biyokütlenin organik gübre olarak kullanılabilmesinden dolayı biyogaz üretimi alternatif yakıtlar içerisinde ön plana çıkmaktadır. Bu amaçla, birçok ülkede biyogaz üretimi ve buna bağlı oluşan biyogübrenin tarımda kullanımı artarak devam ederken ülkemizin bu alandaki potansiyelinin yeterince belirlenemediği görülmektedir. Yapılan bu çalışmada ülkemizin bir ilçesi model olarak incelenerek toplam biyokütle potansiyeli belirlenmiş ve biyokütle potansiyeline bağlı olarak elde edilebilecek biyoenerji miktarı araştırılmıştır. Elde edilen sonuçlar incelendiğinde, model ilçenin biyokütle potansiyelinin ilçenin enerji ihtiyacının üzerinde olduğu ve biyogaz üretimi sonrası oluşacak biyogübrenin kullanımı ile toprak kirliliğine sebep olan inorganik gübre kullanımının azaltılabileceği görülmüştür.
