1. Project Overview

The Zhiran Tiancheng (Beijing) Biotechnology Pinggu Plant Wastewater Treatment Project is an environmental compliance infrastructure project for a cosmetics manufacturing facility located in Beijing.

The plant specializes in plant-based cosmetics, skincare products, and customized personal care formulations. The production process generates complex wastewater containing surfactants, oils, organic polymers, fragrances, and preservatives.

The project implements a dedicated wastewater treatment system to ensure full compliance with Beijing local discharge standards and environmental regulations, while supporting stable and sustainable production operations.
