“…Nonetheless, as documented by Apetorgbor et al (2015), the amount of hemicellulose determined from OPEFB was greater than 30.5% which is still within the range as investigated by Omar et al (2011) and Chang (2014). To improve the nutrients in the substrates, a few research combined the substrate with other supplements such as chicken manure, rice bran, lime, and many others (Malik & Rawat, 2021;Mortada et al, 2020). These added supplements are to boost the amount of nitrogen, carbon, calcium, potassium, and phosphorus in the mushroom, ensuring that it receives enough nutrition.…”

Biodegradation of cellulose, lignin, and hemicellulose from oil palm empty fruit bunches (OPEFB) by straw mushroom (Volvariella volvacea) was investigated. The present research mainly focused on the effects of effective microorganism (EM) treatment (M) and composting duration of OPEFB (C) on straw mushroom production. Two main stages were involved in this research. The first stage was emphasized on the V. volvacea culture process while the second stage was to evaluate the chemical properties of the OPEFB. Zero percent EM solution increased the OPEFB decomposition rate significantly for cellulose and slightly for hemicellulose. The EM solution of 20% increased the OPEFB decomposition rate significantly for hemicellulose after 5 days of composting. In contrast, 10% EM solution increased the OPEFB decomposition rate significantly for cellulose and lignin that were composted for 5 days and for hemicellulose that were composted for 10 and 15 days. The introduction of different EM solutions and varied composting days significantly affected the final compositions of the lignocellulose degraded by the V. volvacea. Most of the lignocellulose composition had positive correlation which depend on the nature of lignocellulose substrates. The final composition of cellulose, lignin, and hemicellulose in the spent OPEFB on average were 44.17 ± 0.04%, 22.66 ± 0.03%, and 11.39 ± 0.04%. Conversely, the raw OPEFB composition were 53.62% + 0.06%, 32.68% + 0.03%, and 15.23% + 0.19%. Based on the reduced percentage of the lignocelluloses, V. volvacea cultivation on OPEFB proved to be a good alternative in degrading biowastes.

“…However, we believe that if CBE fertilizers are used on high commercial-value crops like vegetables, ornaments, or coffee where high-value products can be generated and sold at competitive global markets, the entire process can ultimately produce net positive revenues. Moreover, composting has been found to have potential for commercial viability [ 24 , 55 , 56 ]. Since we focussed on exploring existence of CBE practices and community preferences about their products, we do not yet assess CBE commercial viability in the selected city-regions, in this paper, but in the technical report we found that processors sold organic waste for money.…”

“…Readily available organic waste which makes raw materials cheaper, could enable better access to inputs like compost. For instance, composting has been found to be commercially viable in Asia by Abdul Rahman et al [ 55 ] and Malik and Rawat [ 56 ], implying that it is resource use cost-effective. Nevertheless, composting also bares some costs [ 54 ].…”

Circular bioeconomy in African food systems: What is the status quo? Insights from Rwanda, DRC, and Ethiopia

Increasing global food insecurity amidst a growing population and diminishing production resources renders the currently dominant linear production model insufficient to combat such challenges. Hence, a circular bioeconomy (CBE) model that ensures more conservative use of resources has become essential. Specifically, a CBE model that focuses on recycling and reusing organic waste is essential to close nutrient loops and establish more resilient rural-urban nexus food systems. However, the CBE status quo in many African food systems is not established. Moreover, scientific evidence on CBE in Africa is almost inexistent, thus limiting policy guidance to achieving circular food systems. Using a sample of about 2,100 farmers and consumers from key food value chains (cassava in Rwanda, coffee in DRC, and bananas in Ethiopia), we explored existing CBE practices; awareness, knowledge, and support for CBE practices; consumers’ opinions on eating foods grown on processed organic waste (CBE fertilizers), and determinants of such opinions. We analysed data in Stata, first descriptively, and then econometrically using the ordered logistic regression, whose proportional odds assumption was violated, thus resorting to the generalized ordered logistic regression. Results show that communities practice aspects of CBE, mainly composting, and are broadly aware, knowledgeable, supportive of CBE practices, and would broadly accept eating foods grown CBE fertilizers. Households with heads that used mobile phones, or whose heads were older, or married, or had a better education and agricultural incomes were more likely to strongly agree that they were knowledgeable and supportive of CBE practices and would eat CBE foods (foods grown on processed organic waste). However, the reverse was true for households that were severely food insecure or lived farther from towns. Rwandan and Ethiopian households compared to DRC were less likely to eat CB foods. Policies to stimulate CBE investments in all three countries were largely absent, and quality scientific evidence to guide their development and implementation is currently insufficient.
