At a major paper mill in Southeast Asia, what was once a growing stockpile of pulping residues and rejects has been transformed into a valuable energy resource.

Effective pre-treatment for chemical recycling must achieve both precise particle control and industrial-scale throughput.

This is the hidden ledger behind Harden’s “one-step” solution: not just cost savings, but a strategic lever to capture finished-product premium. As the industry shifts from high-margin to low-margin operations, the competition is no longer about installed capacity—it’s about unit production cost and product value.

Driven by the “dual-carbon” targets and policies promoting solid waste valorisation, co-processing RDF (Refuse-Derived Fuel) in cement kilns has become an industry consensus.

China generates more than 10 billion tonnes of solid waste each year. However, material characteristics vary widely across application scenarios—municipal waste, industrial waste, bulky waste, and more.

Each year, around 18 million tonnes of waste tyres flow into the environment.

Each year, more than 18 million tonnes of end-of-life tyres accumulate, posing not only an environmental challenge but also representing an underestimated reservoir of high-calorific energy.

In plastic chemical recycling, does feedstock particle size truly determine the success or failure of pyrolysis?

For decades, Construction and Demolition (C&D) waste—especially renovation and fit-out debris—was handled through a straightforward approach: recover part of the mineral fraction and landfill or incinerate the rest.
