In the global fight against plastic pollution, over 380 million tons of plastic waste are generated annually (OECD, 2023), with projections estimating a rise to approximately 400 million tons by 2025 due to growing consumption.

At a leading paper mill in Anhui, China, a quiet revolution is underway. Mountains of paper mill residues, primarily light rejects and pulper ropes, along with other industrial solid waste that were once a costly burden, are transformed by Harden’s solid waste processing system into “golden fuel,” a high-calorific feedstock that powers boilers to generate high-temperature steam for papermaking and clean electricity through cogeneration. This case study shows how Harden’s innovative technology overcomes industry challenges, delivering economic, environmental, and social benefits.

Plastic is everywhere in modern life—from morning coffee cups to evening shopping bags—offering convenience at a steep environmental cost. As "white pollution" piles up, chemical recycling emerges as a game-changer, breaking down waste plastics into reusable monomers, small molecules, or fuels.

In the rapidly evolving solid waste industry, shredding technology drives frontend processing efficiency and value. Harden Machinery's one-step shredder has transformed from a niche option to a core solution, powered by market demands and advanced design.

In the high-stakes world of industrial shredding, the power system is the heart of any shredder, driving critical metrics like efficiency, energy costs, and material versatility. What makes a power system truly exceptional?

After a few years, multi-stage shredding systems reveal a hidden profit drain: cutter and accessory costs climbing steadily, fueled by frequent repairs and replacements. Take a three-year-old waste plant we visited—cutter expenses hit $170,000 annually, representing 30% of total ops costs, with maintenance eating 86% of that slice. It's a ballooning burden across procurement, upkeep, and downtime.

At Harden, we transform paper mill rope waste into a valuable resource through advanced solid waste processing solutions.

According to data released by the Intergovernmental Panel on Climate Change (IPCC), biomass has a carbon emission intensity of 18 g/(kW·h), comparable to wind power and negligible compared to fossil fuels like coal, oil, and natural gas.
