(May 29, 2026) As a key fine chemical category, the production process of silica involves the discharge of wastewater, exhaust gas, and solid waste, making environmental protection management a top priority in industry development. Entering the second quarter of 2026, environmental inspections, dual control of energy consumption, and pollutant emission indicator management across the country will be comprehensively tightened, and normalized supervision models will be further implemented. Under the pressure of high policy, the white carbon black industry has bid farewell to extensive production and is now fully implementing a green transformation centered on clean production, recycling, and low-carbon emission reduction, which has completely rewritten the rules of survival and competition within the industry.

In recent years, regulations related to ecological and environmental protection have been continuously refined, with requirements for chemical enterprises being upgraded in areas such as emission standards, exhaust gas treatment, water resource recycling, and solid waste disposal. Traditional sedimentation methods consume a lot of water to produce silica, and it is difficult to treat acidic and alkaline wastewater and salt by-products. In the past, many small and medium-sized factories hovered on the edge of compliance due to rudimentary environmental protection facilities and insufficient treatment capabilities. With the increasing frequency of special inspections nationwide, many regions have imposed production restrictions and rectifications on inefficient and high-discharge production lines within chemical parks, and enterprises that do not meet standards have been directly ordered to suspend production for rectification. After round after round of rectifications, backward small capacity has accelerated its exit from the market, and the industry's overall compliance threshold has risen sharply.

Under regulatory pressure, leading companies took the lead in making efforts, making green production their core strategic direction. Many manufacturers have upgraded their existing production lines technologically, building complete systems for wastewater treatment, flue gas purification, and solid waste recovery, achieving wastewater recycling and reuse, and significantly reducing the proportion of fresh water needed. For by-product waste such as salt and filter residue generated during production, the company explores resource reuse paths, converting waste into other chemical raw materials, turning waste into valuable resources, and reducing solid waste discharge at the source. At the same time, waste heat recovery devices, energy-saving motors, and intelligent temperature control systems are widely used, effectively reducing energy consumption such as coal and electricity, and steadily decreasing carbon emissions per unit product.

Green transformation is not only a compliance requirement but is gradually transforming into product market competitiveness. Currently, mainstream downstream customers—especially large tire companies, new energy material manufacturers, and overseas buyers—have all incorporated environmental protection qualifications, carbon footprint, and green production certification into their supplier assessment systems. Silica products with low-carbon, clean production capabilities are more likely to enter high-quality supply chains. Many companies have proactively carried out carbon footprint accounting and green product certification, creating low-carbon silica series products and forming differentiated advantages in bidding and foreign trade cooperation. In contrast, companies with insufficient environmental investment and inability to provide relevant compliance certificates, even if their products are cheap, find it difficult to connect with mid-to-high-end customers, causing market space to shrink.

The innovation and development of green processes has also become a new competitive track in the industry. In addition to traditional process transformation, new green routes such as rice husk ash production to silica are gradually moving toward industrialization. This process relies on agricultural and forestry waste as raw material, combining resource circulation with low-carbon advantages, aligning with the dual carbon development direction. Currently, multiple pilot production lines are operating stably. Technical exchanges and industry-academia-research cooperation within the industry are becoming increasingly frequent. Research institutions and manufacturers are joining forces to overcome clean preparation technologies, driving the continuous maturity of green processes and sustained cost reductions, turning environmentally friendly production from an "extra burden" into a "development advantage."

Given the current situation, stricter environmental regulations will be a long-term trend, and the path to green development in the white carbon industry will not stop. Industry experts say that in the future, environmental protection, low carbon, and circular capabilities will stand alongside product quality and technological level, becoming essential conditions for companies to establish themselves in the market. In the short term, investment in environmental protection equipment and process upgrades will increase operating costs, but in the long run, green transformation can drive the industry to eliminate outdated capacity, optimize industrial structure, and promote standardized and sustainable development of the entire industry. In the future, companies that uphold the bottom line of green production and continue to deepen environmental protection technologies will continue to enjoy the benefits of industry integration, leading the silica industry into a new stage of high-quality development.
