“…A biogas reactor's function is to convert animal waste, human waste, and other organic matter into biogas. Biogas consumption on a household scale, among others, is used as an alternative fuel for heating and electric generators (Issahaku et al, 2024;Strubbe et al, 2024;Wiloso et al, 2024). Based on the length of development and application of biogas technology around the world, this technology is well established and proven to produce non-fuel energy that is also environmentally friendly.…”

The livestock sector has significant potential to contribute to methane emissions, which are the second largest after CO2, accounting for 13% of total emissions. One solution to control methane emissions is the use of biogas reactors. This study aims to assess the financial aspects of biogas production from livestock waste to meet household energy needs and to determine its financial feasibility. The research employs a qualitative approach that emphasizes flexibility, direct interaction with research subjects, and sensitive interpretation of data context. Data collection was conducted through a literature review by examining and analyzing literature related to the research topic. The literature study results indicate that constructing biogas reactors using cow dung has viable potential for development, especially as a replacement for LPG. However, replacing wood fuel depends highly on the local price of firewood. This study recommends that, for the development of biogas from cattle farm waste to replace firewood, interest subsidies or other assistance are needed to make the development feasible. Additionally, to encourage public interest in developing biogas reactors for cattle farm waste, financial incentives in the form of interest subsidies through program loans are necessary. Developing biogas reactors from cattle farm waste for household energy needs is economically viable, especially as a substitute for LPG, but requires additional support such as interest subsidies to replace firewood. Financial incentives are essential to attract public interest in developing these biogas reactors.

Climate change threatens the livelihoods of Sub-Saharan African farmers through increased droughts. Livestock donation programs offer a potential solution, but their effectiveness under climate stress remains unclear. This study assesses the economic viability of integrating climate-smart technologies (cowsheds and biogas plants) into these programs in Rwanda. Using a stochastic benefit–cost analysis from the beneficiary perspective, we evaluate the net gains for households receiving heifers compared to the current program. Our findings reveal that integrating climate-smart technologies significantly enhances economic viability. Households with cows and climate-smart technologies can possibly realise net benefits 3.5 times higher than the current program, with benefit–cost ratios reaching 5:1. Beyond economic benefits, adopting biogas reduces deforestation, greenhouse gas emissions, and respiratory illness risks. This study demonstrates that integrating climate-smart technologies into livestock donation programs can generate positive economic, environmental, and health benefits, leading to more resilient and sustainable smallholder systems. However, overcoming implementation challenges requires tailored policy packages addressing local barriers.
