Garbage has become an inevitable part of urban growth. Every year, cities and their residents generate hundreds of millions of tons of waste. On one hand, the volume of urban waste keeps rising, while on the other, the foul smell from landfills has turned into a serious challenge in waste management. Rapidly expanding Chinese cities are now facing a "garbage siege," a growing environmental crisis that demands immediate attention.
For many years, China has relied heavily on landfill and composting as primary waste disposal methods. Currently, 80-90% of urban waste ends up in landfills, which not only consumes precious land but also fails to recover valuable resources. Additionally, basic landfill practices without proper treatment can contaminate groundwater and surface water. Exposed garbage leads to the release of harmful gases, as well as breeding pests like flies, mosquitoes, and rats. Even modern sanitary landfills, while preventing groundwater contamination, still require large areas of land and do not fully address the issue of waste reduction.
Composting, though commonly used, is inefficient in reducing overall waste volume and often results in low-quality fertilizers. According to statistics, two-thirds of over 600 large and medium-sized cities in China are surrounded by garbage, and one-fourth have no suitable space for waste storage. The total amount of urban waste in the country has reached 7 billion tons over the years, with an annual increase of around 8.98%. In Beijing alone, daily garbage production reaches 18,300 tons, with an 8% annual growth rate. However, the city's current disposal capacity is only 10.41 million tons per year, leaving a gap of about 8,000 tons per day.
During the "two sessions," Zhou Shengxian, Minister of Environmental Protection, highlighted that the "garbage siege" is a common environmental challenge. He emphasized the need to clarify responsibilities, strengthen waste management, and most importantly, rely on technological innovation to solve the problem.
In response to this pressing issue, the Beijing International Fair on Environmental Technology and Services introduced German advanced waste processing technology, aiming to provide a new solution for Chinese cities. This German project represents the most advanced waste treatment system globally, featuring zero secondary pollution, high energy conversion efficiency, 100% waste reduction, low costs, mature technology, and large-scale application.
The process involves anaerobic fermentation and "liquefaction-gasification" to convert waste into combustible gas for power generation. Compared to traditional incineration-based waste-to-energy systems, this method is more efficient, cleaner, and fully enclosed, ensuring no odor, groundwater contamination, or harmful emissions such as dioxins or heavy metals. It is a truly sustainable and eco-friendly solution.
Through the platform of the Beijing International Trade Fair, the German project team will seek cooperation partners, sign agreements, and secure funding ranging from 3 to 700 million yuan to implement the project. This initiative aims to transform waste into green resources, supporting the sustainable development of cities through technological advancement.
According to the conference organizers, the 2013 Beijing International Trade Fair’s Environmental Service section included the China International Environmental Technology and Service Conference. Supported by several key organizations, the event took place at the Beijing National Convention Center from May 28 to June 1, 2013. Activities included project signings, promotional meetings, fairs, exhibitions, and visits by domestic and international delegations.
The conference attracted top global environmental companies, representatives from 483 member cities, and buyers from both China and abroad. It hosted 4-5 professional promotion meetings, 60 private business negotiations, and offered contract opportunities worth 30-500 million U.S. dollars. It also facilitated mutual visits between Chinese and foreign delegations, promoting international cooperation in environmental services.
This high-level event served as a platform for global environmental collaboration, supporting international environmental projects and facilitating trade between China and the world. It aimed to elevate the standards of China's environmental service industry and contribute to a cleaner, greener future for all.
