“…Because the results obtained show that the greater the concentration of ethanol, the breaking of bonds between cellulose polymer chains in wood increases and the amount of lignin broken down from cellulose also increases. This makes it easier to separate fiber and non-fiber materials and allows the delignification process to take place evenly (Leano & Babel, S. 2011).…”

Today, the continuous use of paper makes various countries experience a tree crisis due to continuous logging. Therefore, the obstacle faced in making paper is the lack of availability of wood raw materials used in the manufacturing process. Currently, various countries are starting to think about other alternatives in paper making. In this study, the use of cassava peels in papermaking can be a solution in meeting the needs of raw materials for papermaking because the content contained in cassava peels can be used as material for making pulp. The experiment of making cassava pulp was carried out using the organosolv process, which is cooking to separate the fibers using organic chemicals. The chemical used in the cooking process is ethanol. The research method used was Completely Randomized Design (CRD). The experiment was carried out with 3 treatments and 3 repetitions. with each concentration of ethanol in the cooking treatment that is 50%, 70% and 90%. Data analysis was carried out by measuring the thickness, gram, age, and tensile strength of the paper. From the experiments conducted, it is proven that using cassava peel can be used as an additional material in making paper. The most effective concentration of ethanol is at a concentration of 90%.

“…There is the need for utilization in several other fields through biotechnological advances. Some of the area that cassava based products have demonstrated positive effect for sustainable management practices including energy production viz: bioethanol [35,[41][42][43], biogas [44][45][46][47][48], bio-electricity using microbial fuel cells technology [49][50][51][52][53]; animal feed production [22,26,54], bio-surfactants [55], raw materials for production of amino acids [26], enzymes [56,57], organic acids etc. The conversion of the potential cassava mill effluents to bio-valued products could create employment for several families especially in region of high cassava production.…”

Most food processing effluents are discharged into the environment with little or no treatment. Nigeria is the largest cassava producing nation. Cassava processing is majorly carried out by smallholder processors especially in Southern Nigeria. The effluents generated in the dewatering zone are lethal to lives probably due to the acidic and/ or cyanide content. This study estimated the quantity of cassava mill effluents that is often discharged into the environment during gari production. Projections based on growth scenarios viz: current, low and high growth rates were made. Cassava production historical data (literature reviews/ secondary data) for Nigeria were used for the study. Results revealed that 57.134 million tons of cassava was produced in 2016 leading to release of about 5.142 million tonnes of cassava mill effluents. Projections showed that before 2035, Nigeria may likely produce at high, low and current status growth rate 79.544, 73.850 and 57.719 million tons of cassava leading to the release of 7.158, 6.646 and 5.194 million tonnes of cassava mill effluents, respectively. After considering the challenges of gathering cassava mill effluents in Nigeria, only 45-65% of total effluents generated could be gathered for large scale utilization. Cassava mill effluents has demonstrated positive effect for utilization through biotechnological advances including biogas, bio-ethanol, bioelectricity (energy), animal feed, enzymes, bio-surfactant, organic acids among other. Hence there is the need for more research into these areas for optimization and possibly commercialization to avoid the attendant environmental impacts associated with the effluents.

“…Due to the presence of alternative electron acceptors, such as nitrate and sulphate, low Coulombic efficiency (η c ) values have been a perennial issue with MFCs designed to use wastewaters (Leano et al, 2011). However, although cassava has a high level of cyanide in its pulp and peel, the effect of the presence of cyanide has not been shown to have any detrimental effect in an MFC fed with cassava wastewater (Kaewkannetra et al, 2011).…”

In a number of energy-poor nations, peel from cassava processing represents one of the most abundant sources of lignocellulosic biomass. This peel is mostly discarded indiscriminately and eventually constitutes a problem to the environment. However, energy can be extracted from this peel in a microbial fuel cell. In this study, the viability of cassava peel extract as a substrate in a single-chamber air cathode microbial fuel cell is demonstrated, and optimum performance conditions are explored. The effects of different pretreatments on the extract are also discussed in the context of observed changes in the internal resistances, conductivity and Coulombic efficiencies. At the best conditions examined, the extract from cassava peel fermented for 168 h and adjusted to a pH of 7.63 attained a peak voltage of 687 mV ± 21 mV, a power density of 155 mW m of reactor volume and a Coulombic efficiency of 11 %. Although this energy is limited to direct use, systems exist that can effectively harvest and boost the energy to levels sufficient for supplementary energy usage in cassava producing regions.
