The report analyzes the South African waste sector, which is worth approximately R15 billion and employs 29,000 people. It highlights the Western Cape's higher recycling rates (14%) compared to the national average (9.8%) and examines various waste streams, including plastics, paper, glass, metals, e-waste, and construction and demolition waste. The document identifies significant barriers to waste-to-energy (WtE) projects, such as complex municipal procurement processes and regulatory hurdles, while outlining potential for biogas generation from agricultural and organic waste. It also details GreenCape's initiatives, such as the Western Cape Industrial Symbiosis Programme (WISP), to promote a circular economy.

The Western Cape government reports significant investment in its green economy, including R20bn allocated to the renewable energy sector in 2013 and specific industrial projects like wind turbine tower manufacturing and solar panel production. Key initiatives include the Green Economy Strategic Framework, the Western Cape Industrial Symbiosis Programme (WISP), and the establishment of a cleantech Special Economic Zone in Atlantis.

The South African waste economy, valued at R15.3 billion, is transitioning from 'end of pipe' to 'cradle to cradle' solutions under the National Environmental Management: Waste Act. While the recycling rate stands at 19.6%, the sector faces significant hurdles in municipal procurement, feedstock security, and legal authorisation backlogs. In the Western Cape, municipalities like Cape Town, Drakenstein, and Stellenbosch are pursuing waste-to-energy and organic waste treatment to address critical landfill airspace shortages, with some landfills estimated to have less than 3 years of capacity remaining.

The South African waste economy is valued at R15.3 billion, representing approximately 0.51% of GDP. While the National Environmental Management: Waste Act (NEM:WA) has shifted the sector toward 'cradle-to-cradle' solutions, developers face significant hurdles, including complex municipal procurement processes, long legal authorisation backlogs, and difficulties in securing long-term feedstock agreements. In the Western Cape, limited landfill airspace—with some sites having less than three years of capacity—is driving a need for decentralized waste-to-energy and recycling projects.

The report provides a framework for China to move from the rhetoric of a circular economy (CE) to implementation by establishing a robust system of indicators. It argues that material flow analysis (MFA) is the most relevant tool for this purpose, as it allows for the monitoring of physical material and energy flows across macro, meso, and micro levels. The document details key MFA indicators—such as Direct Material Input (DMI) and Total Material Requirement (TMR)—and examines how the European Union, United States, and Japan have institutionalized these measures to track eco-efficiency and the decoupling of economic growth from environmental pressure. It concludes with recommendations for China to integrate CE indicators into national accounts and collaborate with international practitioners.

The report outlines a comprehensive approach to revitalizing the Cuyahoga Valley by treating environmental restoration as an economic driver. It proposes specific interventions for the 5.5-mile ship channel, including the implementation of low-impact development (LID) for stormwater, the creation of aquatic habitats like pocket wetlands and green bulkheads, and the establishment of an industrial symbiosis network called 'Waste = Revenue'. The document argues that moving away from traditional 'gray' infrastructure toward 'green' solutions will improve water quality, attract investment, and create new local business opportunities in restoration services.

The document details a 'closed loop' system where Cape Town Market diverts organic waste to Elgin Fruit Juice's anaerobic digester in Grabouw to produce electricity. The resulting digestate is transported back to Cape Town Market, where Ywaste uses it as a carbon-based additive to create compost for farmers. This synergy results in 1,400 tonnes of organic waste diverted from landfills annually, a reduction of 1,000 tonnes of fossil greenhouse gases, and an annual saving of R550,000 for Cape Town Market.

The Western Cape Industrial Symbiosis Programme (WISP) facilitated a one-off exchange where Dekro Paints recycled 4 tonnes of expired solvents from Protea Chemicals. This diverted hazardous waste from landfills, reduced carbon emissions by 19.4 tonnes of CO2e, and saved Protea Chemicals R135,000 in testing, transportation, and landfill fees.

The Fugard Theatre in Cape Town generated approximately 110 half-used batteries per week due to performance safety requirements, leading to a stockpile of 3,000 batteries. WISP established a partnership to redirect these batteries to the City of Cape Town’s Disaster Risk Management Department and various charities for use in torches, radios, and medical devices. This initiative saves the City of Cape Town R21,000 annually and reduces the extraction of virgin materials. Because South Africa lacks battery recycling operations, spent batteries are sent to the Uniross collection programme for mineral extraction or concrete encapsulation and hazardous landfill disposal. An attempt to switch the theatre to rechargeable batteries was unsuccessful as they did not meet the technical specifications for the microphones.

The document details a resource efficiency project where WISP connected Farbe Designs, a clothing company in Stellenbosch, with CSK Material Handling to manage textile, plastic, and paper waste. Because the Western Cape lacks textile recyclers, CSK collects and bales the waste in Cape Town before transporting it to KwaZulu-Natal, where textiles are shredded for carpet underfelt production. The collaboration results in 20 tonnes of waste diverted from landfills annually and an estimated R8 000 in annual savings for Farbe Designs.

The Western Cape Industrial Symbiosis Programme (WISP) connected Duferco Steel Processing and FS Smit with Cape E-Waste to manage stockpiles of electronic waste. This arrangement diverted over a tonne of hazardous waste from landfills, resulting in cost savings of R470 per tonne for the companies and the creation of three jobs for dismantling equipment.

The document outlines the investment proposition for the Atlantis Special Economic Zone (ASEZ), focusing on its role as a greentech manufacturing hub. It details available land, infrastructure, and a range of national and municipal incentives, while providing specific cost data for electricity, water, and labour in the Western Cape region.

The Western Cape Industrial Symbiosis Programme (WISP) connected Ywaste, a composting service provider, with two waste generators—Cape Town Film Studio (CTFS) and Samson Bedding—to source carbon-rich sawdust. Ywaste uses bokashi composting and vermiculture to convert organic waste into nutrient-rich soil. This synergy diverts approximately seven tonnes of sawdust from landfills annually and reduces greenhouse gas emissions by 2.3 tonnes per year.

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 potential for industrial symbiosis by using waste foundry sand (WFS) as a secondary material in sectors like brickmaking and road construction. It highlights the economic benefits for foundries and off-takers, the regulatory hurdles involving waste classification and management licenses, and the technical requirements for processing WFS to ensure product quality.

ACA Threads transitioned from using single-use virgin polypropylene spools to a buy-back and recycling system. By partnering with an injection moulder and social organisations, the company recovered 7 tons of material from landfills over five years, saving over R460,000 and generating income for disabled persons' organisations and local community projects.

The document details how the Western Cape Industrial Symbiosis Programme (WISP) connected Enviroserv, a waste management company, with ComboTimber Structures, a pallet refurbisher. This collaboration shifted ComboTimber Structures' business model from manufacturing virgin wood pallets to using second-hand materials, resulting in 79 tonnes of wood diverted from landfills and the creation of three permanent jobs.

The Western Cape Industrial Symbiosis Programme (WISP) is a free service delivered by GreenCape and initiated by the Western Cape Government. It employs an industrial symbiosis approach to match unused resources—including energy, water, and materials—from one company to another to create economic and environmental benefits. The programme specifically targets gaps faced by SMEs in implementing resource and energy efficiency, aiming to reduce CO2 emissions and landfill costs while increasing profits and innovation.

The document details a synergy facilitated by the Western Cape Industrial Symbiosis Programme (WISP) between Pallet Cycle, a recycled timber manufacturer, and Cabrico, a clay brick manufacturer. In early 2020, Cabrico took 4.6 tonnes of wood waste from Pallet Cycle to use as fuel for its kiln and dryers, resulting in a reduction of 1.7 tonnes of greenhouse gas emissions and decreased reliance on fossil fuels like coal. The partnership provided economic benefits through lower fuel and material costs for Cabrico and increased storage space for Pallet Cycle.

The document details a project facilitated by the Western Cape Industrial Symbiosis Programme (WISP) where Global Energy installed an anaerobic digestion plant at Rennie Farms. The project converts 1.5 tonnes of daily vegetable waste into biogas for combined heat and power, as well as digestate for soil enhancement and irrigation water. The initiative resulted in R319,740 annual savings in landfill fees and averted 876 tonnes of fossil greenhouse gas emissions per year.
