This project looks at the design and feasibility of a scalable pyrolysis machine for the production and use of biochar in the agriculture industry as a means of addressing degraded soils and improving food security.

According to the United Nations (2017) The global population is expected to reach 9.8 billion people by 2050. To accommodate the growth in population, agricultural production will need to increase by 60% to meet the growing needs (International Atomic Energy Agency 2022). Climate change and poor soil management practices continue to degrade soils with expectations that 90% of the earth's surface will be degraded by 2050 (Joint Research Centre 2018). This will place the agriculture industry under intense pressure particularly as the effects of climate change is forecast to decrease crop productivity by 10% by then (Joint Research Centre 2018).

The Project is separated into three phases Research, Design and Analysis. The research phase covers a literature review on soil degradation focusing on anthropological impacts, the benefits of char in soil remediation and productivity and identification of sustainable feedstocks for char production. Research was also conducted in various methods for char production to disrupt the natural carbon cycle. In the design and analysis phases computational fluid dynamics will assist in optimising system efficiency.
