Since its founding in 2003, Welle has grown from a small office to a GEM-listed company with over 2,000 employees and 100+ subsidiaries. Throughout this journey, Welle has focused on three core business areas: urban environment, industrial environmental protection, and energy services. We continuously innovate through industrial internet and big data, investing heavily in research and development to offer comprehensive environmental solutions and services. Welle has evolved from a landfill leachate expert to a leader in organic waste resource recovery, holding a leading position in areas such as landfill leachate, kitchen waste, anaerobic biogas, and VOC recovery. With the vision to "build a beautiful green homeland" and the mission to "beautify the environment for humanity," we stay committed to our core values of being customer-focused, innovative, and open to win-win cooperation, while taking on our responsibility for sustainable development and social impact.
