Taking control of the investment costs, an enabler for T2T recycling.
Demand for recycled polyester is approaching 10 million tonnes per year, yet the market remains structurally undersupplied with material that meets industrial quality requirements. While significant recycling capacity has been announced globally, many projects struggle to reach Final Investment Decision. For Rewin, a competitive capital expenditure is a key technology factor in enabling industrial scale‑up.
The imbalance between growing demand and limited supply has resulted in a sustained price premium for high‑quality recycled polyester. This signals strong market fundamentals but also highlights a structural challenge: industrial deployment of recycling capacity is not keeping pace with ambition. For Rewin, this gap underscores the importance of technologies that can be scaled efficiently, both technically and economically.
Growing demand but a limited supply
The demand for recycled polyester continues to increase, driven by regulation, brand commitments and the need to reduce reliance on virgin materials. At the same time, the availability of recycled polyester that meets industrial performance requirements remains limited.
This creates an opportunity for chemical recycling technologies that can upgrade low‑quality waste streams into recycled polyester suitable for demanding applications. Rewin’s focus is on enabling such solutions at industrial scale, where material quality, process reliability and cost efficiency must be combined.
Abundant feedstock with a constrained industrialisation
Large volumes of raw material are already available for recycling. Post‑industrial waste streams, such as textile cuttings, account for an estimated 10–15 percent of produced fibres, while post‑consumer textiles represent an emerging waste pool with very large, long‑term volumes.
Despite this, recycling capacity remains constrained. The limiting factor is not access to abundant low-value feedstock, but the ability to convert these streams into recycled polyester with consistent quality, competitive costs and industrial robustness.
The opportunity for polyester recycling has attracted significant attention in recent years. According to Rewin’s market research, an aggregated pipeline of more than 1.5 million tonnes of annual recycling capacity has been announced globally.
However, many of these projects are struggling to progress beyond planning and development phases. A key reason is capital expenditure. Recent project announcements indicate total investment costs ranging from EUR 250 to 1,000 million, corresponding to approximately EUR 3–9 million per 1,000 tonnes of annual recycling capacity. At these levels, projects face high capital intensity and elevated risk, making it difficult to reach Final Investment Decision.
CAPEX control as a core technology feature
For Rewin, CAPEX intensity is a fundamental technology feature and not a project outcome. Together with an equipment supplier, Rewin has conducted a detailed cost study for a first industrial‑scale plant with a capacity of 20,000 tonnes per year based on Rewin’s chemical recycling technology.
The study indicates that Rewin’s process design and equipment integration can maintain capital requirements at substantially lower levels. Even at this initial full‑scale level, the results point to a CAPEX footprint below EUR 1.2 million per 1,000 tonnes of annual recycling capacity.
Lower CAPEX directly improves project viability by reducing upfront capital requirements and lowering overall project risk. For Rewin, this strengthens the pathway from pilot and demonstration activities to a first full‑scale plant, while establishing a scalable platform for future global deployment.
As demand for recycled polyester continues to grow and regulatory requirements tighten, technologies that combine feedstock flexibility, product quality and capital efficiency will be essential in translating announced ambitions into operating industrial assets.
