Liying Ecotech Unveils Mobile Sterilization for Medical Waste

As healthcare systems grapple with the risks of secondary pollution during medical waste disposal and the high costs of long-distance transportation, achieving closed-loop "treatment at source" management has become a critical challenge in public health. The MDV series of mobile medical waste treatment vehicles, developed by LiYing EcoTech, provides an efficient, safe, and environmentally friendly on-site disposal solution for remote areas, public health emergencies, and regions with limited medical resources through its highly integrated onboard microwave sterilization system.

I. Core Technical Specifications and System Architecture

The MDV series offers two models—LYC-5150 and LYC-5180—to accommodate different scale requirements. The LYC-5150 has a total weight of 15 tons with dimensions of 9780×2550×3990 mm, while the LYC-5180 weighs 18 tons and measures 10150×2550×3990 mm. Both models reach a height of 6500 mm when fully deployed and are equipped with 150 kW onboard generators, with an installed power capacity of 120 kW (including a 72 kW steam generator). Their processing capacity remains stable at 300 kg/h (±10%).

The microwave system consists of ten 1.25 kW units operating at 2450 MHz (±50 MHz), ensuring comprehensive pathogen penetration. This design eliminates the need for chemical additives while maintaining rigorous sterilization standards.

II. Treatment Process and Microwave Sterilization Mechanism

The MDV series achieves a fully automated closed-loop process from collection to final treatment:

• Pre-treatment: Infectious waste enters the pre-storage hopper through the rear loading system.
• Shredding: A feeding arm transfers waste to the dual-axis shredder, reducing bulk items into fine particles to increase surface area for heat exposure.
• Sterilization: Shredded material enters the microwave and insulation sections, where combined thermal and biological effects denature bacterial proteins and deactivate vital biological substances.
• Discharge: Sterilized waste is expelled via a screw conveyor, after which it can be safely disposed of in municipal landfills or recycling facilities as general waste.

The scientific basis of microwave sterilization lies in its dual mechanisms: thermal effects cause polar molecules in microorganisms to absorb energy, leading to protein denaturation, while non-thermal effects disrupt molecular structures through high-frequency electric fields, eliminating microbial viability at the molecular level.

III. Applications and Technical Advantages

The system handles diverse high-risk medical waste including blood products, surgical waste, pathological specimens, sharps, laboratory waste, and protective clothing, demonstrating broad-spectrum sterilization capability.

Compared to traditional incineration or chemical disinfection methods, the MDV series offers significant advantages:

• Environmental sustainability: Fully enclosed processing prevents harmful byproducts like dioxins and acidic gases, meeting stringent environmental standards.
• Energy efficiency: Microwave heating provides deep penetration without energy loss, while all-electric operation further reduces running costs.
• Space and labor optimization: Compact integrated design requires minimal space, and high automation enables complete operation with just two personnel.
• Operational flexibility: Mobility makes it ideal for remote areas or cross-regional services, with instant start-stop capability that eliminates storage risks and reduces logistics expenses.

This mobile treatment technology represents both an advancement in medical waste processing and a critical component of modern public health emergency response systems, providing practical technical support for achieving "zero transportation, zero pollution" in medical waste management.
