FAQs About Our Sustainability

Q01What are Nanjing Tianhua Technology Co., Ltd.’s core commitments regarding environmental protection, employee relations, and the use of renewable energy?

A01Nanjing Tianhua Technology is committed to reducing its environmental impact through innovative, eco-friendly products. Our production relies 100% on renewable clean energy sources for electricity. We ensure high employee standards, having passed the SMETA CAPR audit. Protecting the environment and user health are central to our corporate social responsibility.

Q02What specific measures has Nanjing Tianhua Technology Co., Ltd. implemented in its production processes to reduce its environmental footprint?

A02We actively promote clean production, for example, by optimizing production processes, selecting recyclable and biodegradable raw materials, using pipeline transportation, improving energy efficiency, and reducing pollution and waste generation. We place particular emphasis on the sorting, recycling, and safe disposal of production waste, and we continue to invest in research and development to identify more environmentally friendly alternatives to raw materials, thereby reducing our overall environmental impact.

Q03What energy-saving and cost-reduction benefits can a fully automatic dispensing machine bring to food and pharmaceutical manufacturers?

A03Automated dispensing machines, when integrated into a complete production line, reduce the burden on companies associated with redeveloping production lines, improve operational efficiency, and lower development costs. Precise, metered dispensing minimizes waste of powdered deoxidizers and desiccants; low-power motors reduce electricity consumption in the production area; and an integrated forming process reduces waste of composite adhesives and film. At the same time, these machines reduce workers’ exposure to dust, thereby improving the working environment in the production area.

Q04What specific environmental sustainability measures have been implemented throughout the entire production process for our oxygen absorbers and desiccants?

A04We have established a comprehensive ESG environmental system covering the entire closed-loop process from raw materials to production, packaging, and waste management: mineral raw materials such as iron powder and montmorillonite undergo deep purification, and arsenic, lead, and cadmium leaching levels strictly comply with GB 4806 and GB/T 41896-2022. Furthermore, all production raw materials are naturally occurring substances, resulting in zero carbon emissions.

Q05What specific circular economy implementation measures are in place for montmorillonite desiccants and silica gel desiccants, respectively?

A05Montmorillonite desiccants undergo deep purification of the raw ore to reduce soluble heavy metals and can be recycled as soil conditioners after they lose their effectiveness; cobalt-free, eco-friendly silica gel desiccants can be regenerated and reused after drying. Production waste from both types of products is fully recycled, pelletized, and reintroduced into the production line, achieving zero solid waste — a key strength in the environmental pillar of the company’s ESG performance.

Q06How do bulk desiccants and desiccants specifically designed for export packaging help foreign trade companies achieve their ESG carbon reduction goals?

A06Bulk desiccants eliminate the need for unnecessary individual outer bags, reducing packaging redundancy. Our export-grade products are made entirely from FSC-certified kraft paper and PLA compostable film, while medical oxygen-absorbing agents use DuPont Tyvek packaging film — all of which comply with the EU’s PPWR packaging regulations. We provide full life-cycle LCA carbon footprint reports for our products, helping to reduce carbon tariffs on cross-border shipments and ensuring easy compliance with overseas brands’ green supply chain ESG audits.
