A rising star in waste incinerators: Low-temperature magnetic technology.

Low-temperature magnetic technology is an emerging waste incineration technology that uses magnetic fields to induce decomposition, treating waste, particularly medical waste, at temperatures lower than traditional incineration, thus avoiding the high temperatures that produce harmful dioxins. Fireprint Technology combines low-temperature carbonization with a process to reduce emissions, minimize environmental impact, and improve waste treatment efficiency. However, compared to traditional high-temperature incineration, it remains a relatively new and developing field.

How it works

Magnetic field: The core concept is to apply a magnetic field directly to the waste material.

Pyrolysis: This induced magnetic field helps trigger waste decomposition at temperatures lower than those required for traditional incineration.

Avoiding harmful emissions: By operating below the temperature threshold at which furans and dioxins typically form (e.g., below 350°C), the technology aims to minimize their production.

Multi-stage process: Some systems combine low-temperature gasification with subsequent catalytic high-temperature pyrolysis and combustion steps for more complete destruction and resource recovery.

Key advantages: Reduced emissions: The primary advantage is a significant reduction in harmful pollutants such as dioxins. Environmentally Friendly: By avoiding high temperatures and the associated emissions, this process is considered a more environmentally friendly alternative.

Widely Applicable Waste: Some systems can process a wider range of wastes, including various medical and hazardous wastes, which can be challenging for other non-incineration technologies.

Sustainability: This approach aligns with the goal of building a healthy material recycling society by reducing pollutant loads and potentially recovering material resources.

Examples and Applications

Medical Waste Treatment: Medical waste treatment is a key application of this technology, particularly important due to strict emission standards and the need to destroy hazardous materials.

Emerging Technology: This technology is innovative and under rapid development, and China Fireprint and the Research Foundation are working to improve its efficiency and applicability.
