Xiaohuanggou
The first national comprehensive operation service provider of smart environmental protection in China
About Xiaohuanggou
Xiaohuanggou Environmental Technology Co., Ltd. operates as a smart recycling and waste management service provider. Founded in August 2017 by Tang Jun, who also founded P2P lending platform Tuandaiwang and was the chairman of Paishing Technology Group, the company entered the market with a vision to revolutionize urban waste management. Its business model centered on deploying smart recycling bins in high-traffic urban areas such as residential communities, office buildings, and commercial districts.
These smart bins were designed to accept various types of recyclable materials, including paper, plastics, metal, textiles, and glass. Users would interact with the machines via an app or a user interface on the bin, select the material type, and deposit their items. The system would then weigh or count the items and provide an instant monetary reward to the user's account, which could be withdrawn upon reaching a certain threshold. This 'cash for trash' model was intended to incentivize public participation in recycling. The company managed its own logistics, with dedicated personnel to collect the materials when the bins were full and transport them to processing facilities.
The company's trajectory was marked by rapid expansion and significant investor interest. In June 2018, Xiaohuanggou secured a notable RMB 1.05 billion in a Series A funding round led by Zhongzhi Enterprise Group, achieving a post-money valuation of RMB 6 billion. This capital injection was aimed at scaling up the production and deployment of its smart bins. However, the company's fortunes took a sharp downturn in March 2019 when its founder and chairman, Tang Jun, was investigated for illegal fundraising activities related to his other company, Tuandaiwang. This event triggered a severe financial crisis for Xiaohuanggou, leading to a freeze on its funds, nationwide operational halts, and mass layoffs. Consequently, the company filed for bankruptcy and restructuring in September 2019. Following the restructuring, with its second-largest shareholder, Zhongzhi International, stepping in as the re-organizer, the company has been working to recover and resume operations.
