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 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.

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.

The document assesses the potential for Western Cape businesses to leverage time-of-use (TOU) tariffs through BESS arbitrage, comparing the repurposing of existing systems against new installations. It finds that while upgrading existing BESS offers high internal rates of return (IRR), new installations are more sensitive to tariff escalation rates and investment horizons, with a 15-year outlook generally improving financial performance.

The document provides a guide for Western Cape businesses on adopting solar PV to reduce energy costs and carbon footprints. It details various financing models—including outright purchase, debt finance, and Power Purchase Agreements (PPAs)—and provides pricing benchmarks for 2025/26. The brief highlights the role of municipal feed-in tariffs and national tax incentives, while warning of risks related to changing utility tariff structures and policy shifts.

The document argues that collective action between government, businesses, and citizens is essential to address South Africa's water availability and quality challenges. It showcases several successful water stewardship models, including nature-based solutions like invasive alien plant clearing, community-based rangeland and spring protection, and municipal water loss reduction through leak repairs and valve refurbishment. These projects are presented as cost-effective alternatives to traditional grey infrastructure, offering measurable returns in water yield, job creation, and social benefits.

Mediclinic implemented solar PV across 29 hospital sites, using a PPA model for 10 sites, including Durbanville Hospital, to avoid upfront costs. The Durbanville installation, commissioned in November 2021, consists of a 704.6 kW (DC) system that produces approximately 1.17 GWh of green electricity annually, offsetting about 1,076 tons of carbon emissions. The 25-year take-or-pay PPA provided immediate savings, with initial electricity prices approximately 60% lower than municipal rates. The document highlights the benefits of PPAs for operational de-risking and financial hedging against rising grid costs, while recommending clear maintenance responsibilities and sector-specific provider experience for similar projects.

The Hartenbos wastewater treatment works (WWTW) in the Western Cape has implemented a hybrid microgrid consisting of solar PV and battery energy storage (BESS) to ensure operational continuity during loadshedding. The system, completed in September 2025 with a cost between R100 million and R112 million, allows the facility to island from the grid, reduce diesel reliance, and export surplus power. The project serves as a model for other municipalities to stabilize critical services and lower energy expenditures through embedded renewable energy.

GreenCape has issued a Request for Proposals (RFP) for a legal service provider to assist in developing a Waste Management Policy and Regulatory Tool. The tool is intended to help municipalities and project developers navigate the complex legal requirements for implementing alternative waste treatment technologies in South Africa, specifically within the Western Cape province.

The GreenUp initiative in Khayelitsha, Cape Town, is a collaborative recycling project launched in June 2019 by Distell with support from the City of Cape Town and Western Cape Provincial Government. The project integrates waste pickers into the formal waste management system by providing infrastructure, training, and equipment, enabling them to collect and sell recyclables to buyback centres. Between 2019 and 2022, membership grew from 62 to 120 people. In 2020, the project diverted 60-100 tonnes of recyclables from landfills and generated income for members between R80,000 and R120,000. The model is presented as a potentially replicable approach for implementing extended producer responsibility (EPR) regulations by incorporating the informal sector.

GreenCape has issued RFP SIDAFF 01/2025 to appoint a Professional Service Provider for the project preparation of two water infrastructure projects in the Swartland Municipality. Project A involves upgrading the Swartland Water Treatment Works from 29Ml/d to 40Ml/d (est. R305 million), and Project B involves upgrading the bulk pipeline between Malmesbury and Darling (est. R200 million). The preparation must follow ECSA guidelines and IFC/World Bank environmental and social standards, focusing on technical feasibility, financial bankability, and climate resilience. The procurement is phased, with initial stages fixed-fee and later stages based on confirmed project costs.

This Request for Proposal (RFP No. SIDAFF 01/2026), issued by the GreenCape Sector Development Agency on 24 June 2026, seeks a service provider to conduct a 7-day sampling, testing, and analysis campaign at the Vredenburg Wastewater Treatment Works (WWTW) in the Saldanha Bay Local Municipality. The data collected will inform the design of proposed upgrades to the facility.

This document is a Request for Quotation (RFQ) issued by GreenCape for a service provider to conduct project close-out evaluations for an intervention titled "Active climate change citizenship for a just transition in South Africa." The project, co-financed by the European Union, aims to empower citizens, women, and youth to participate in democratic processes regarding climate mitigation and adaptation, specifically within the renewable energy sector.

The document serves as a reference sheet for groundwater application processes, listing key contacts at the City of Cape Town (CoCT), the Department of Environmental Affairs and Development Planning (DEA&DP), and the Department of Water and Sanitation (DWS). It also catalogues official guidelines, bylaws, and presentations related to the National Water Act and water use licenses.

The Western Cape has a potential wheeling market of up to 1,600 MW of new renewable energy, representing an investment opportunity of up to R25.6bn. While wheeling allows customers to purchase power from independent power producers (IPPs) via existing grids, its uptake is hindered by limited municipal capacity and the requirement that municipalities be in good financial standing with Eskom. To address these barriers, Eskom is piloting 'virtual wheeling', expected to launch in early 2025, which allows municipal customers to access energy from Eskom-connected IPPs without waiting for municipal readiness. Current wheeling in the province is limited to a few local municipalities, including the City of Cape Town, George, and Swartland. The document highlights that wheeling can provide significant cost savings and price stability for businesses through bilateral power purchase agreements (PPAs), though long-term financial models should account for potential future decreases in daytime energy tariffs.

The document analyzes the alignment of water services by-laws in Western Cape municipalities with the 2005 Department of Water Affairs and Forestry (DWAF) model by-law. It identifies gaps in regulatory clarity, highlights specific business risks such as industrial effluent permits and water audits, and notes that municipalities with more recent updates generally provide better certainty for investors and operators.
