This industry brief by GreenCape explores the economic and environmental opportunities of diverting waste foundry sand (WFS) from landfills in South Africa, specifically focusing on the Western Cape and the City of Cape Town. It details how WFS can be repurposed as a secondary raw material for industries such as brickmaking and road construction, provided that strict legal classifications and hazard management protocols are followed.

This industry brief by GreenCape examines the financial viability of using battery energy storage systems (BESS) for tariff arbitrage in the Western Cape, South Africa. It focuses on leveraging time-of-use (TOU) tariffs to reduce energy costs by charging batteries during off-peak periods and discharging during peak periods, particularly as the decline in loadshedding has left many existing BESS installations underutilised.

This industry brief by GreenCape provides guidance for businesses in the Western Cape on installing behind-the-meter (BTM) solar PV systems to reduce electricity costs and improve energy security. It details financial viability factors, pricing benchmarks for 2025/26, various financing models including Power Purchase Agreements (PPAs), and the role of municipal feed-in tariffs and national tax incentives in South Africa.

This industry brief by GreenCape highlights replicable water stewardship projects in South Africa, specifically in the Western Cape and KwaZulu-Natal. It showcases the effectiveness of nature-based solutions, such as invasive alien plant clearing by the Greater Cape Town Water Fund, and infrastructure improvements like leak repairs in schools funded by an FMCG company.

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 model involving the City of Cape Town, Distell, and Waste Plan. Launched in 2019, it integrates informal waste reclaimers into the waste management system, providing them with training, PPE, and infrastructure. The project grew from 62 to 120 members by 2022, diverting 60-100 tonnes of recyclables from landfills in 2020 and providing a replicable model for Extended Producer Responsibility (EPR) regulations.

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.
