Project Overview

案例概述

In March 2022, Longshen Rongfa launched a green low-carbon transformation project in its factory area in Dingyuan Town, Yuzhong County, Lanzhou City, Gansu Province, focusing on the core directions of "space operation optimization" and "resource recycling". The project includes building a 500kW solar photovoltaic system, upgrading sewage and waste gas treatment facilities, constructing a herb residue-organic fertilizer recycling chain, and introducing a fully automatic intelligent dropping pill production line. By December 2024, the project provides 656,000 kWh of green electricity annually, with a water recycling rate of over 90%, 100% herb residue recycling, and 2.33 tons of annual nitrogen oxide emission reduction. It has obtained the "Municipal Green Factory" certification and become a model of green operation for Chinese patent medicine enterprises.

2022年3月，陇神戎发在甘肃省兰州市榆中县定远镇厂区启动绿色低碳改造项目，聚焦“空间运营优化”与“资源循环利用”核心方向：建设500千瓦太阳能光伏系统、升级污水废气处理设施、构建药渣-有机肥循环链、引入全自动滴丸智能化生产线。截至2024年12月，项目年提供绿电65.6万千瓦时，水循环利用率超90%，药渣100%回收，氮氧化物年减排2.33吨，获“市级绿色工厂”认证，形成中成药企业绿色运营典范。

Project Highlights

项目亮点

The project prioritizes the use of existing resources, such as building PV on factory roofs (occupying no new land) and utilizing existing production wastewater to create a circulation system. It innovates by establishing a "production-herb residue-planting" ecological chain, achieving synergy between industry and the environment. The company has obtained "Municipal Green Factory" and "National High-Tech Enterprise" certifications, as well as 2.7 million yuan in government technological transformation subsidies.

项目优先利用厂区屋顶建设光伏（不新增占地），也利用了既有生产废水用以改造循环系统，搭建“生产-药渣-种植”生态链，实现了产业与环境的协同。企业获“市级绿色工厂”、“国家高新技术企业”认证，和政府技改补助270万元。

Project Impact & Sustainability

项目影响力、可推广性与可持续性

1. Innovation Value: Technically, it achieves the integration of "PV + energy storage + load matching" (replicable for high-energy-consuming pharmaceutical enterprises). Institutionally, it integrates party building with ESG governance and establishes a "green KPI assessment" (e.g., linking workshop energy consumption compliance rates to performance).

2. Industry Promotion: It provides a full-chain green transformation template (covering energy, resources, and pollution) for Chinese patent medicine enterprises. It has hosted 12 peer companies for site visits and study tours, and its related technologies have been cited in the "Green Production Guide for the Traditional Chinese Medicine Industry."

3. Sustainability: The follow-up plan is to expand the PV installed capacity to 1000kW in 2025 and explore the "green electricity direct supply + carbon trading" model. It will also cooperate with local governments to expand the application of its herb residue organic fertilizer to 20,000 mu of Chinese medicinal materials planting bases, continuing to enhance its circular ecology model.

1、创新价值：技术上，实现“光伏+储能+负荷匹配”一体化（可复制至高能耗药企）；机制上，将党建与ESG治理融合，建立“绿色KPI考核”（如车间能耗达标率与绩效挂钩）。

2、行业推动：为中成药企业提供“能源-资源-污染”全链条绿色改造模板，已接待12家同行考察学习，相关技术获《中药行业绿色生产指南》引用。

3、可持续性：后续计划2025年扩大光伏装机至1000千瓦，探索“绿电直供+碳交易”模式；与地方政府合作推广药渣有机肥至2万亩中药材种植基地，持续深化生态循环。
