Solving the Pain Points of Food Waste Treatment: How the KQ-KG-LY Series Screw Press Drives Industry Transformation through Efficient Solid-Liquid Separation

Globally, food waste disposal is facing severe challenges. Data shows that the annual output of food waste in major Chinese cities has reached as high as 60 million tons, and is continuously rising at an annual rate of 8%, accounting for over 35% of the total municipal solid waste. Meanwhile, policy-driven forces are strong. According to the "14th Five-Year Plan for the Development of Urban Domestic Waste Classification and Treatment Facilities", by 2025, China's food waste resource utilization rate needs to be increased to over 60%, and the coverage rate of treatment capacity should reach 90%, which will directly drive an equipment investment market of over 30 billion yuan.

However, the industry still faces numerous pain points: high operating costs, mismatch between processing capacity and actual demand, low added value of resource-based products, and the severe global competition and trade environment, which together constitute the main challenges in the current market. Against this backdrop, the KQ-KG-LY series screw presses launched by our company aim to provide the industry with an efficient, economical, and reliable Solid-Liquid Separation solution through innovative physical pressing technology.

I. Core Pain Points and Market Opportunities in the Industry

1. There is a huge gap in processing capacity, and the potential of the county-level market is emerging

Currently, the coverage rate of food waste treatment facilities nationwide remains at a relatively low level, especially in county-level markets, where there is a significant gap between treatment capacity and generation volume. This has created vast market space for distributed and modular treatment equipment. Our company's KQ-KG-LY series models, with their flexible model configurations (treatment capacity ranging from 3 to 10m³/h), perfectly meet the needs of county-level and distributed treatment scenarios.

1. High operating costs and profitability under pressure

Traditional anaerobic fermentation, aerobic composting, or incineration treatment technologies generally suffer from problems such as high energy consumption and the need to add chemical flocculants, resulting in persistently high operating costs. This not only erodes project profits but also poses potential risks to the long-term stable operation of the project.

1. The level of resource utilization is low, and the value chain urgently needs to be upgraded

Although resource utilization is policy-driven, the added value of current resource utilization products from food waste (such as organic fertilizer and biogas) is generally low, and market channels are also highly dependent on government matchmaking, with the proportion of market-based transactions insufficient. How to lay the foundation for high-value-added resource utilization in the back end (such as black soldier fly breeding and biodiesel production) through efficient front-end dehydration has become the key to improving the overall project revenue.

1. The global market landscape is being reconfigured, and technological competitiveness has become the key to going global

The adjustment of US tariff policies has brought cost challenges to Chinese equipment enterprises, but at the same time, it has also forced enterprises to seek breakthroughs through technological upgrading and market diversification. The competitive advantage of Chinese enterprises is shifting from "price advantage" to "dual drivers of technology and brand". The core components of our company's equipment are made of SUS304 Stainless Steel and coated with wear-resistant coating. Their corrosion resistance and excellent processing technology fully meet the access standards of most global markets, providing strong equipment support for partners to expand non-China markets.

II。KQ-KG-LY Screw Press: A Technical Solution Addressing Industry Pain Points

Based on the above industry insights, our screw press has taken solving market pain points as its core objective since the very beginning of its design.

Core technological advantages:

1. Ultimate operational economy

（1）Energy Saving and Consumption Reduction: Adopting the principle of pure physical pressing, the dehydration process does not require any heat source, with unit energy consumption far lower than that of thermal drying equipment, directly reducing operating costs.

（2）Zero chemical addition: No flocculant needs to be added throughout the entire process, which not only saves chemical costs but also avoids secondary pollution from chemical agents to subsequent resource utilization (such as composting and aquaculture), ensuring the purity and market value of resource-based products.

1. Excellent dewatering performance empowers resource utilization

（1）Low moisture content: Through professional mechanical calculations and parameter customization, optimization is carried out based on the characteristics of different materials (such as fiber content, viscosity), enabling the moisture content of materials to be reduced to an extremely low level.

（2）Large throughput and continuous operation: The unique spiral design enhances axial thrust, effectively resolving stubborn issues such as "slippage", "bridging", and "material return" that cause shutdowns, ensuring 24-hour uninterrupted and stable operation of the equipment, and significantly improving the processing capacity per unit time.

1. Exceptional reliability ensures the stable operation of the project

In response to the complex composition and strong corrosiveness of food waste, the key components of the equipment are designed with dual protection against wear and corrosion. The core components are made of SUS304 stainless steel, which has excellent acid resistance, alkali resistance, and corrosion resistance, significantly extending the service life of the equipment, reducing maintenance costs, and minimizing the risk of downtime.

III. Technical Parameters and Scenario Applications

Technical Parameters Overview:

Wide range of application scenarios:

- Source reduction and pre-treatment of food waste

- Organic Waste Recycling Project (e.g., fruit and vegetable residues, slaughter waste)

- Dehydration of fibrous materials (such as sawdust, straw, bagasse)

- Pulp dewatering and dewatering of medicinal herb extraction residues

Choosing the KQ-KG-LY screw press is not just about selecting a piece of equipment; it's about choosing a reliable partner who can help you tackle industry challenges, reduce operating costs, and enhance resource utilization value.
