In March 2024, the Electronic Waste Association of South Africa (eWASA) confirmed that a 31% post-consumer recycling rate for polystyrene had been achieved for the 2022/2023 reporting year. This milestone formally qualifies polystyrene — including expanded polystyrene (EPS) — for recyclable status under South Africa’s extended producer responsibility (EPR) regulation.
The result was verified and announced in line with the national Packaging EPR Scheme, where eWASA serves as the registered Producer Responsibility Organisation (PRO) for polystyrene. The scheme requires transparent, audited recovery and fund reinvestment to maintain compliant status.
Compressing EPS for scalable recovery
One of the key enablers behind the 31% figure is the deployment of ingot machines — densification units that compress bulky EPS waste into compact, high-density bars. This greatly reduces the volume and cost of transport, especially in urban and peri-urban collection settings.
In 2023, more than 2,060 tonnes of polystyrene were recovered and processed — most of it through eWASA-managed and affiliate-aligned infrastructure. The collected EPS was repurposed into lightweight concrete bricks, picture frames, cornices, and skirting boards.
The rate exceeded South Africa’s second-year threshold of 25%, which determines whether a packaging material may be classified as recyclable. Reaching this level was necessary for polystyrene to continue bearing the official recyclability symbol under government guidelines.
Reframing EPS as recoverable — by performance, not perception
According to eWASA, the result confirms that EPS can now be formally classified as recyclable within South Africa’s packaging policy framework — a status that was conditional on verified outcomes, not assumptions of recoverability.
The result also affirms that infrastructure integration is advancing, with PRO-driven investment helping to scale collection and compaction capacity.
This marks a structural shift: from viewing EPS as a problematic material to treating it as a recoverable, circular input, subject to the same systemic design principles applied to other packaging types.
