Industry Brief: Waste-to-Energy

The document provides a guide for businesses in South Africa to evaluate waste-to-energy (WtE) options, categorising technologies into anaerobic digestion, thermal processes, and biofuels. It outlines the regulatory landscape, including the National Environmental Management: Waste Act and NERSA regulations, and highlights upcoming policy shifts such as organic waste landfill bans in the Western Cape. The brief emphasizes a structured project development process—from scoping and pre-feasibility to execution—to ensure financial and technical viability.

• Waste-to-energy solutions can offer businesses financial and operational advantages by reducing waste management costs through lower gate fees compared to landfills, decreasing logistic costs, and improving energy security by reducing reliance on the utility grid.
• Three primary categories of waste-to-energy technologies are available: anaerobic digestion (biogas) for organic waste and wastewater; thermal waste-to-energy (incineration, pyrolysis, and gasification) for high calorific value and low moisture residues; and biofuels produced from energy crops, wood-based residues, and animal fats.
• The implementation of waste-to-energy projects in South Africa is governed by a complex regulatory framework, including the National Environmental Management: Waste Act (59 of 2008) for feedstock, the Occupational Health and Safety Act (85 of 1993) for operations, and the National Energy Regulator of South Africa (NERSA) for energy products.
• Several policy developments are expected to drive WtE demand, including the Western Cape's plan to implement 50% organic waste landfill bans by 2022 and 100% by 2027, and amendments to the Electricity Regulations Act increasing the generation license capacity threshold for independent power producers to 100 MW.
• Each WtE technology has distinct market barriers: anaerobic digestion is sensitive to feedstock imbalances and produces odour; incineration is capital intensive and can destroy non-metal recyclables; pyrolysis and gasification are capital and energy intensive; and biofuels face food security debates and high financing risks for 2nd and 3rd generation technologies.
• Successful project implementation requires a phased development process starting with scoping and pre-feasibility to assess feedstock availability and site suitability, followed by a detailed feasibility stage for plant design, costing, and securing necessary permits.
