The World Economic Forum (WEF) partnered with the Western Cape Industrial Symbiosis Programme (WISP) to manage tear-down waste from a 2015 event at the Cape Town International Conference Centre. By identifying resource types and volumes two months in advance, WISP connected the WEF with solution providers to repurpose pine wood, carpeting, promotional materials, and PVC banners. This initiative diverted 11.8 tonnes of waste from landfills, saved 10 tonnes of fossil greenhouse gas emissions, and generated approximately R242,000 in total economic benefits.

The document outlines the role of energy storage systems in improving the resilience and sustainability of South African municipal wastewater treatment works. It focuses on lithium-ion (Li-ion) batteries due to their market dominance and a 90% cost reduction since 2010. While energy storage does not reduce overall energy consumption, it provides backup power and enables higher renewable energy penetration. The factsheet compares three financial scenarios: stand-alone storage, storage replacing diesel generation, and storage paired with solar PV, noting that the latter two offer better payback periods and internal rates of return. It also details various financing mechanisms available to municipalities, such as grants, concessional loans, and energy performance contracts.

Additionally, it provides a menu of financing mechanisms, including grants and energy performance contracts, to support the adoption of energy efficiency and renewable energy technologies.

The document outlines energy efficiency (EE) strategies for pumps and motors in South African wastewater treatment works, noting that pumping can account for 4% to 30% of a facility's energy use. It categorizes interventions by payback period and energy savings potential, ranging from no-cost operational adjustments to capital-intensive retrofitting. Potential energy savings from these combined interventions can exceed 50%. The factsheet also details various financing options, including municipal budgets, grants, concessional loans, and energy performance contracts, to support the deployment of these technologies.

The document outlines specific power consumption (SPC) benchmarks for primary and tertiary wastewater treatment technologies in South Africa. It identifies that while these stages are not energy intensive, efficiency can be improved through peak demand management, equipment idling, and UV disinfection upgrades, with potential energy savings of up to 50% for UV systems.

The document outlines how municipal wastewater treatment works (WWTWs) in South Africa can reduce energy consumption and carbon footprints through optimized sludge management. It details specific technical interventions in primary sedimentation, dewatering, thickening, and stabilisation, while providing a business case for biogas production and a framework of financing mechanisms for implementing these energy efficiency projects.

The document outlines how solar PV technology can be integrated into South African municipal wastewater treatment works (WWTWs) to lower energy bills and greenhouse gas emissions. It details various installation configurations, such as ground-mounted, floating, and rooftop systems, and provides financial metrics including a payback period of 4 to 8 years. The factsheet also lists potential financing mechanisms and a step-by-step implementation process for municipal officials and private developers.

The document outlines how mini-hydro and wind energy can be integrated into South African municipal wastewater treatment works (WWTWs) to lower energy bills and greenhouse gas emissions. Mini-hydro is presented as highly compatible with WWTW infrastructure, utilizing water flow and elevation drops to generate electricity, with a typical payback period of 5 to 10 years. Small-scale wind is described as a supplementary option to offset grid use, though it is less common due to cost and the need for multi-year wind studies. The factsheet also provides a framework for financing these projects through municipal budgets, grants, concessional loans, and energy performance contracts.

The document advocates for the use of thermal hydrolysis as a pre-treatment for anaerobic digestion in wastewater treatment works (WWTWs) to increase biogas production and reduce sludge mass. It highlights that South African municipalities spend over R300 million annually on sludge disposal and suggests that thermal hydrolysis can improve digester efficiency, reduce carbon footprints, and provide a payback period of 2-5 years. The factsheet also outlines various financing mechanisms, such as municipal budgets, grants, and energy performance contracts, to support the adoption of these energy efficiency and renewable energy technologies.

The EU's Farm to Fork Strategy aims to make Europe climate neutral by 2050 by transforming food manufacturing, processing, and transportation. Key targets for 2030 include reducing chemical pesticide use and risk by 50%, cutting nutrient losses by at least 50%, reducing fertiliser use by at least 20%, and increasing organic farming to 25% of EU agricultural land. The strategy will influence trade policy to secure commitments from third countries on animal welfare and pesticide use. For SADC EPA countries, which exported approximately USD 2.5 billion to the EU in 2020, these changes present both cost implications and opportunities driven by shifting consumer preferences. South Africa is the most affected SADC EPA state, accounting for 76% of these exports, with edible fruits (51%) and fisheries (26%) being the top export sectors.

The document presents Controlled Environment Agriculture (CEA) as a method to maximize food yield using indoor facilities and climate-regulated systems. It identifies key drivers for CEA adoption in South Africa, including severe water scarcity, soil loss, and high rates of urbanization. The study highlights benefits such as year-round production, reduced food mileage through vertical farming, and improved pest control. To scale the industry, the document argues for increased access to affordable financing and dedicated resources for research, development, and skills training.

The document defines non-sewered sanitation systems (NSSS) as reticulation-free systems where human excreta are stored on-site for treatment or disposal. It highlights the economic return of water and sanitation investments, noting a USD 2.5 - 5 return in reduced healthcare costs for every dollar spent. In South Africa, NSSS are presented as solutions to water scarcity, aging infrastructure, and rapid urbanization, with a potential R4.7bn investment opportunity in metropolitan projects and a R3.4bn government allocation for school sanitation over two years. Globally, the document projects that water infrastructure costs will rise from USD 6.7 trillion by 2030 to USD 22.6 trillion by 2050, with Sub-Saharan Africa leading in annual costs to achieve basic and safe sanitation.

The document advocates for decentralized wastewater treatment in South Africa to address infrastructure deterioration and high costs associated with centralized systems. It identifies key benefits such as non-potable water reuse and sludge beneficiation for energy and fertilizer, while noting a R33bn annual funding shortfall in the water and sanitation sector. Regulatory drivers include a national target to divert 75% of organic waste from landfills by 2030 and a liquid waste to landfill ban by 2027.
