Abstract
Purpose
Agricultural food residues (agro-residues) receive low economic returns and experience disposal problems. The food production and processing is often not configured to supply agro-residues for production of bioenergy needed in food processing. The feasibility of utilising agro-residues through advances in postharvest technology for sustainable bioenergy conversion is reviewed. The paper aims to discuss this issue.
Design/methodology/approach
Agro-residues from maize, sugarcane and potatoes in five African countries were assessed from secondary data to identify suitable conversion technologies, energy products and configurations of bioenergy plants for applications in postharvest food processing.
Findings
Strategic alignment of postharvest technology to bioenergy production systems is vital to advancing both food production and bioenergy that benefit rural communities in Africa. High economic returns are possible when the bioenergy plants are either annexure to existing agro-processing operations or operate as a biorefinery.
Research limitations/implications
Assessment of energy self-sufficiency of food production and processing systems is required.
Practical implications
Agro-residues for bioenergy production require investments in infrastructure for storage, transportation and processing of the residues, and development of new risk management techniques.
Social implications
The rural communities will be energy secure resulting in food security through reduced postharvest losses and increased agricultural productivity.
Originality/value
The study stimulates innovative thinking in establishing sustainable bioenergy systems for food processes.
