Tantech Subsidiary Launches Innovative Driverless and Autonomous Street Sweepers

LISHUI,China,Nov. 16,2020 -- Tantech Holdings Ltd (NASDAQ: TANH) ("Tantech" or the "Company"),a clean energy company in China,today announced the launch by its subsidiary,Shangchi Automobile Co.,Ltd. ("Shangchi Automobile"),of two highly innovative driverless and autonomous street sweepers.The Shangchi SC-120A model features unmanned,automatic sweeping,and the Shangchi SC-120B model features manned,autonomous,intelligent sweepingle.

Shangchi Automobile has a long history in vehicle development. The company was founded in 2011,with manufacturing based in Zhangjiagang City,Jiangsu Province. Its innovative driverless and autonomous street sweepers being launched today,were designed for quieter operation and improved cleaning performance,with the ability to reduce or eliminate the 7 to 8 humans required for typical sweeper vehicle operation. Lidar-based,machine vision technology will enable the driverless model to safely and accurately operate in common environments. The sweepers have two primary operating modes,cleaning and litter-collecting,and can be used for 10 hours at a time or until full. The multi-patented vehicles will come with 1 year warranties.

Mr. Wangfeng Yan,Chief Executive Officer of Tantech,said,"The sanitization market is long overdue for major innovation to increase performance and lower operating costs. It is common to find sweepers still using inefficient,suction technology designed 70 or so years ago requiring expensive,heavy power consumption. We are very excited about the potential for both of our new,state-of-the-art models,which are capable of delivering a higher return on investment to the government organizations,cleaning services and businesses that we are targeting. Both vehicles are undergoing pilot programs,with mass production planned for the first half of 2021. Initial sales are expected to be primarily in the domestic China market,followed by international demand in Europe and North America."

Mr. Yan continued,"The move to develop special use vehicles follows changes in China's national subsidy policy to encourage usage of new energy vehicles and the application of unmanned operation of special use vehicles. We developed very attractive,feature rich vehicles that integrate information collection technology,data analysis systems,artificial intelligence controls,positioning and navigation systems,automatic actuators,and safety assurance technology. Our innovative street sweepers integrate highly intelligent route learning and memory,and real-time deep learning,in order to facilitate assisted driving or driverless driving."
