“…The process of converting biomass to biochar leads to sequestration of about 50% of the initial Carbon content compared to the low amounts retained after biomass decomposition about 10% after 10 years [2]. Biochar hence offers a significant measure for climate change mitigation and restores the lost soil nutrients [10].…”

Effective utilization of coffee wastes has been a great challenge in Uganda despite their wider use to replenish soil organic matter. This study explored the possibility of producing biochar from coffee husks that could be used as a soil amendment for replenishing soil nutrients and also for enhancement of soil water holding capacity. Pyrolysis of coffee husks was done in a batch bio-reactor under slow pyrolysis conditions of temperatures 350˚C-550˚C and residence times 30-60 min. For easy characterization, biochar was grinded, sieved through a 1 mm sieve and then analyzed using a computerized Thermo Graphic Analyzer with an inbuilt and integrated ELTRA 84 GmbH Precision Digital weighing scale. Proximate analysis (wet basis) of biochar gave a moisture content of 5.2%, ash content of 14.7%, volatile matter of 13.2% and fixed carbon of 66.9%. Biochar was applied to soil at different rates (0%, 5%, 10% and 20% w/w) and its effect on water holding capacity was investigated. Results show that biochar amended soils had higher water holding capacity (p ≤ 0.05) compared to biochar free soils. The water holding capacity also increased with increase in biochar amendment with a 1.5% increase in soil water holding capacity for each 1% increase in biochar application rate. Biochar was also rich in soil nutrient elements with 0.96% N, 0.39% P and 1.97% K; this increased the availability of soil nutrients for crop growth. The results suggest that biochar could be a better tool to improve soil conditions thus enhancing the sustainability of agriculture.

“…Over the years, soil studies have attracted researchers as a sink for the atmospheric CO 2 (Singh et al, 2018). Biochar can be incorporated into the soil using either power tiller or ox-plough without affecting its performance (Ndhlovu, Kiggundu, Wanyama, & Banadda, 2017).…”

One of the key aspects of a green economic development model of a country is to develop indigenous resources and local expertise while utilizing sustainable technologies. This review explored the possibilities of utilizing jackfruit waste for production of biogas, briquettes and biochar. In many of the developing countries, there is huge potential for organic waste conversion into appropriate energy solutions. These can contribute to developing rural areas especially small holder farmers and diversifying the available energy sources. Biomass waste like jackfruit waste when managed well can produce bio-energy, but also the GHG emissions need to be reduced from unmanaged, decomposing organic material. When put to use, agricultural biowastes like jackfruit waste could be used as raw materials in the production of bio-products (biofuels, biochar, bio pesticides), briquettes, among others. The biochar can be mixed with the soil producing carbon-rich soils and contribute to CO2 sequestration and soil fertility. This paper reviews works focused on using jackfruit waste for anaerobically producing of biogas, briquettes and biochar for improved crop production. The paper concluded that jackfruit waste can anaerobically decompose to produce biogas and it can also be used for briquette production. It was further concluded that jackfruit waste can undergo decomposition at high temperatures to produce biochar which can be incorporated into the soil creating a CO2 sink hence helping in mitigating the effects of the climate change.

Applications of Biochar for Environmental Safety

Biochar is among the environmentally friendly bio-products possible of enhancing agricultural productivity due to inherent properties. Despite the increased biochar research output, the sustainability of biochar production and its applicability in developing countries is mostly uncertain. This chapter underscores the biochar production process, its environmental usefulness, and the prediction of its potential impact on agricultural productivity in East African countries. Currently, pyrolysis technology is the most effective means of biochar production. Predominantly, biochar is useful in carbon sequestration, soil amendment, and as a solid fuel source. In-depth analysis of crop residues production in East African countries vis-à-vis the potential for biochar production and the total planted areas strongly indicate that biochar could be sustainably produced and applied in agriculture without compromising the forests and the environment. This knowledge is vital in guarantying the feasibility of biochar technology among policymakers as a sustainable alternative to the exorbitant mineral fertilizers.
