Sustainable Industrial Waste Management Solutions for SMEs in Steel & Coal Coke

Introduction: Tackling the Growing Challenge of Industrial Waste  

In the steel and coal coking plants, many small and medium-sized enterprises (SMEs) have long relied on off-site disposal or temporary storage to manage industrial waste such as dust, powder, and sludge. However, increasing regulatory pressure and operational challenges are making these approaches less sustainable.

In reality, industrial solid waste has always been an unavoidable part of daily production. For SMEs in the steel and coal coking industries, how to manage and reuse these waste streams is not only a matter of compliance, but also a key factor that affects production stability, operating costs, and overall resource recovery efficiency.

Why Industrial Waste Management Has Become a Key Challenge for SMEs 

Compared with large steel industries or integrated coking plants, SMEs often face more practical limitations in waste management. As a result, many solutions that seem simple in theory are difficult to run in a stable way over the long term.

These challenges come not only from the complex nature of the waste itself, but also from constraints in technology, investment, and environmental compliance.

Diverse Waste Sources

In SMEs, solid waste is usually generated across multiple production processes. The waste types are diverse, change frequently, and are hard to manage in one centralized system. Different operating steps continuously produce various powders and fine residues, which keeps waste management under constant pressure.

These industrial waste often share similar characteristics:

• Fine particle size or a high share of fines, which can easily create dust and increase on-site management pressure
• Complex composition, with noticeable changes in moisture and impurity levels
• Limited volume for each single waste type, making it difficult to support large continuous treatment systems
• Frequent but scattered generation, which affects cost control and production stability over time

As a result, many SMEs end up in a situation where the total volume is not huge, but the waste becomes difficult and costly to manage, and its long-term impact cannot be ignored.

Technical Limitations

SMEs frequently struggle with low briquetting efficiency, often due to improper binder selection or suboptimal particle size distribution. High concentrations of harmful elements such as Zinc in dust and ash hinder effective metal reduction.

Outdated equipment fails to meet modern emission standards, resulting in non-compliance. These limitations not only reduce operational efficiency but also increase the cost and complexity of waste treatment.

Reliance on External Disposal

Without a stable on-site reuse solution, many SMEs still rely on off-site disposal. However, this approach brings not only transportation and handling costs, but also strong dependence on local policies, disposal permits, and third-party capacity.

When external disposal options tighten, companies may face disposal delays, rising stockpiles, and disruptions to normal production, sometimes even leading to output reductions or shutdowns.

Financial and Operational Barriers

Traditional waste treatment technologies, such as rotary hearth furnaces (RHFs), involve substantial upfront investments—often reaching millions of dollars. SMEs typically lack the financial flexibility to support such investments.

Further challenges include the complexity of advanced processes, like dezincification, which require highly skilled technicians; production delays due to lengthy installation periods and frequent maintenance needs; and operational disruptions, which can lead to lost revenue and decreased competitiveness.

Regulatory & Compliance Pressure

Governments around the world are enforcing tighter regulations on industrial emissions and waste disposal. For example, Vietnam’s goal to modernize its steel industry by 2030 includes specific requirements for sustainable development. Failure to comply with these evolving regulations can result in fines, penalties, landfill bans, carbon taxes, and significant reputational damage.

Briquetting: A More Practical Sustainable Industrial Waste Management Solution for SMEs

By compacting fine powders into regular briquettes, briquetting significantly reduces dust generation and material losses, while improving efficiency in transportation, storage, and furnace charging. It also helps stabilize furnace feeding and enhance in-furnace recovery by limiting powdering and segregation.

In the steel industry, briquetted iron-bearing waste can be efficiently recycled back into furnaces or sintering processes. In coal and coking plants, briquetted coal and coke fines can be reused as fuel or reducing agents, reducing return fines and improving material utilization.

However, for SMEs, the key challenge is how to maintain consistent briquette strength and low return fines under fluctuating raw material quality and complex impurity conditions.

This means that equipment alone or a general-purpose binder is often insufficient. A sustainable briquetting solution must be based on material-specific binder design, optimized formulations, and well-matched process parameters to ensure long-term operational stability and efficiency.

Jianjie’s Comprehensive Industrial Waste Management Solutions Tailored for SMEs

Jianjie offers a portfolio of cost-effective, scalable, and sustainable waste management technologies tailored to the unique needs of SMEs in steel and coal coking plants. These solutions empower SMEs to reduce waste, recover valuable materials, and maintain compliance with environmental standards

Core Technology: Upgraded Briquetting and Dedicated Binder Solution

Jianjie has developed an integrated cold briquetting solution supported by environmentally friendly polymer binders, designed specifically for solid waste and fine materials commonly found in the steel and coal coking industries. The solution focuses on improving briquette strength, process stability, and long-term operational reliability under fluctuating raw material conditions.

Compared with conventional approaches, Jianjie’s briquetting binders deliver clear and practical advantages:

• Higher and more stable briquette strength
• Reduced fines generation and return fines during handling and use
• Lower material losses in transportation, storage, and charging
• Improved suitability for continuous and stable production

For high-temperature metallurgical applications, briquettes offer good heat resistance and stable behavior. They can be safely used in typical operating conditions, such as charging into electric arc furnaces (EAF), converters, and sintering processes, meeting the practical requirements of steel plant operations.

Material-Specific Binder Solutions for Complex Industrial Waste 

In terms of binders, Jianjie has developed multiple series of dedicated briquetting binders tailored for materials characterized by fine particle size, large quality fluctuations, and complex impurities. Instead of relying on general-purpose binders, Jianjie’s approach is based on material-specific matching.

Currently, Jianjie’s binder solutions are applicable to a wide range of fine industrial waste, including both steelmaking byproducts and metallurgical mineral fines, such as:
