Solid Waste Management
Solid waste management, or preferably Integrated Solid Waste Management (ISWM), is a comprehensive waste prevention, recycling, composting, and disposal program. An effective ISWM system considers how to prevent, recycle, and manage solid waste in ways that most effectively protect human health and the environment.
Currently, China is the world’s largest municipal solid waste generator, and expectations are for its waste output to continue rising. To tackle the growing waste management crisis, China will need to develop additional hundreds of landfills and waste-to-energy plants in the next years.
European municipalities (or waste companies), together with EC-Link Project, really can make a difference when it comes to guiding Chinese municipalities and local companies to segregate their waste and recyclable materials in order to minimise their costs.
Authorities in eastern China are turning to the courts to raise the millions of Yuan needed to rehabilitate water and land polluted by dumping from an illegal lead-acid battery recycling plant.
State-run Xinhua news agency reported on Wednesday that the city of Huaian in Jiangsu province would use “public interest litigation” to pay to remove the acid and heavy metals found to around the plant and a nearby river.

On the morning of December 20th, the Guilin City’s Shankou Domestic Waste Incineration Power Generation Project was officially ignited after three years of construction. The project will not only undertake the task of harmless treatment of domestic garbage in the city, but also produce green energy for daily life use of the citizens, which marks the realization of treatment of domestic garbage in the manner of “garbage great reduction, utilization and harmlessness” in the city.
Shankou Project is located in Shankou Village, Lingui Town, Lingui District. It covers an area of about 147 mu and is invested and operated by Shenzhen Energy Environmental Protection Co., Ltd., with a chartered period of 30 years. The first phase of the project will design and build 2 sets of mechanical grate furnaces with a daily processing capacity of 750 tons. The furnaces are working with the medium-temperature medium-pressure waste heat boiler system, one 35MW (MW) steam turbine generator set, flue/gas purification system, slag collection and storage system, and fly ash collection and stabilization system, sewage treatment system, circulating cooling system, and other equipment. It uses the process of “waste full-burning + fly ash stabilization + residual landfill”, and uses the waste heat from waste incineration to generate electricity. The project has been implemented since December 2015. After more than three years of hard work, it has built a modern domestic waste incineration and power generation plant that is superior to the national standard and even the EU environmental protection technology standards.
According to the relevant person in charge of the project, after the project is put into production, it can annually treat 547,500 tons of domestic garbage, generate 210 million kWh which can be used by the project itself, or sold 180 million kWh to the grid. Equivalently, it can annually save 66,000 tons of standard coal and reduce carbon dioxide emissions by 220,000 tons. At the same time, it can also reduce waster weight by about 80%, or in other words, reduce waste volume by more than 90%, effectively alleviating the problem of garbage disposal in the built-up area of the city and saving land resources. With the first phase of the project being put into operation, the second phase of the project is about to start that will expand the scope to achieve solid waste incineration full coverage, and fundamentally solve the problem of urban and rural domestic garbage pollution.
The government said in July that households across the nation will, for the first time, have to pay for garbage disposal by 2020 and, separately, that limits on landfills will be tightened. Other recent initiatives include raising recycling quotas in 46 major cities, including Beijing and Shanghai. Revised laws and follow-up implementation mean that the solid-waste market is only going to expand. The greatest potential is in sectors like garbage incineration and hazardous waste disposal, along with garbage classification and the expansion of household waste management from urban to rural areas.
China's imports of solid waste fell 56.3 percent in the first half of 2018, the result of tough new restrictions and a crackdown on smuggling. Total waste and scrap imports reached 9.98 million tonnes over the six month period. The government has sought to relinquish its role as the world's biggest recipient of waste as it bids to curb pollution and move up the global supply chain, and banned imports of 24 types of foreign waste, including plastics, at the beginning of this year, and it has also imposed tough quality restrictions on other recyclable materials, including scrap metal.

An announcement from the Central Committee of the Communist Party of China asserts the country’s determination to eliminate imports of solid waste by the end of 2020. However, it is not yet clear whether this is a new policy or a reaffirmation of a strategy from last year. Some institutions predicts further changes to Chinese standards and laws in order to affect its recycled raw material needs as the country, not self-sufficient in recycled raw materials, will need to import them for their manufacturing needs.
CREMONA, Italy — On Saturday mornings, residents of this tidy city of 72,000 crowd into a former market for fruit and vegetables in order to donate old clothes and housewares or pick up a used toy or book.
Second-hand markets are nothing new, of course. But the one here, inauguralted a year ago and known as the Centro del RI-USO, is part of a much larger and very forward-looking local policy on waste management that seeks to reduce what residents throw away and increase what gets reused and recycled.
Cremona has become a European test ground for new ideas to promote a “circular economy” — a concept that seeks to reduce waste and extend the useful life of resources. In the last two years alone, Cremona has increased the percentage of waste collected separately — necessary for recycling — from 53 percent to 72 percent.
The city has made recycling easier by implementing door-to-door collection. That’s still quite unusual in Italy — in Rome, residents must take their paper or glass to special bins on the street. In Cremona’s city centre, residents put paper in bins outside their buildings one day and plastics, glass or organic waste on other days. Vehicles of different sizes make the pickups — smaller vehicles are used in the narrow streets of the city centre.
Cremona is also testing the introduction of a tariff on the waste that can’t be recycled. In two neighbourhoods, the city gives residents orange 60-litre trash bags; the more bags residents put out, the higher their trash collection fees. The idea is to send residents a price signal that encourages them to reduce the amount of material they throw away.
“Waste recycling is not only a social matter, but also cultural,” says Mayor Gianluca Galimberti, who has made increasing the amount of waste recycled a key priority since his election in 2014. “The level of waste recycled says a lot about the community, its relationship with things and the surrounding environment. That is the reason that pushed us to work hard on this objective. And we got an historic result for the city, laying firm foundations for further actions toward a circular economy.”
Reducing waste is serious business in Cremona. There’s a deputy mayor in charge of promoting a circular economy here, Alessia Manfredini. She works on communicating with residents to foster behavioural changes, such as properly separating recyclables. And she’s led Cremona officials on tours of recycling centres across Northern Italy.
“The comparison with other cities was important for us in order to better define our strategies and actions in the field,” Manfredini says. It also helped the city connect with broader waste-related initiatives and funding streams across Europe, she says.
This local commitment toward dialogue with other cities, as well as universities and research centres, pushed Cremona to lead a larger European project on waste-management strategies. It’s called UrbanWINS,and it’s financed by the European Commission. Launched in July 2016, the project is analyzing current strategies for waste prevention and management in 24 European cities (Bucharest, Turin and some municipalities near Rome are among the pilot cities) with the objective of highlighting the most innovative plans.
The three-year project, also involving global networks such as ICLEI - Local Governments for Sustainability, as well as various European universities, NGOs and the Italian Institute of Statistics, will study the “urban metabolism”. That is, it will look at how materials flow through cities and seek a better understanding of what gets produced, consumed and discarded.
The main objective of the project is to help local governments define more holistic strategic plans that not only deal with waste more efficiently but also prevent waste from being created in the first place. One of the tools expected to be developed is a model that demonstrates material flows in different kinds of urban contexts: big cities, small ones, industrial centres or historical places.
“This tool is innovative in Italy because it is not only based on the analysis on the amount of waste produced but on the consumption of materials,” says Livia Mazzà of Ecosistemi, an environmental consultancy and scientific partner of UrbanWINS. “It will reflect on the sources of production and promote a deeper understanding on reducing and reusing waste.”
Another tool of the project is to foster an active dialogue about waste among local residents and stakeholders. Waste management is not typically a big topic of public-participation schemes in Europe. But in June, Cremona and other cities involved in the project hosted the first of several public debates — or agoras — over how residents perceive waste management and how it can be improved. Online detates are coming as well.
Cremona is planning to make the agora a permanent forum for public dialogue on waste management. Keeping the local community engaged will be a challenge, particularly on an issue that many people prefer not to think about. But officials here hope that the public will remain engaged if they can continue developing concrete actions that improve quality of life.
One focus area is in the schools. Since 2014, the city has hosted an annual competition called Piccoli Passi, or “small steps”. It’s aimed at fostering sustainable behaviours among students and administrators. Lesson plans about recycling begin each year in March. In May, an official measurement of recycling at each school begins. The schools are ranked and children at the schools that do best get rewards. Another part of the schools competition focuses on reducing food waste in canteens.
The city is also taking aim at food waste in restaurants. In Italy, it’s unusual for restaurant patrons to bring home any leftovers from their meal — it’s seen as a sign of hunger or poverty. So uneaten food ends up in the trash. Cremona is working on changing that attitude through a campaign called Tenga il resto, or “keep the rest”. The city has distributed 100,000 recyclable containers to two dozen restaurants, in hopes of convincing patrons that bringing leftovers home is the right thing to do for the environment.
Cremona is also looking to strengthen the role of the Centro del RI-USO, which is managed by a community group called Amici di Emmaus. It’s intended not only as a second-hand market but also as an incubator for practices of urban sustainability. For example, there will be trainings for children and families on how to reduce the amount of materials they consume. A group that promotes purchases of foods and goods produced locally or through “fair-trade” supply chains will also host meetings.
Mayor Galimberti says all of these strategies and more will be needed to make the circular economy a reality in Cremona. “What is needed is a multidisciplinary and systemic approach,” he says. “A local community well educated to the use of the things is a community that lives better.”
On September 19-21, EC-Link Project, with the support of MoHURD, EUD and the Hefei Municipality has organized an Inter-City Lab (ICL) focused on water management, solid waste management and clean energy sectors.
The event has seen the participation of 120 delegates representing 8 European cities (Barcelona, Berlin, Bordeaux, Hamburg, Liverpool, Mannheim, Valencia and Växjö), 7 Chinese provinces (Anhui, Guangdong, Guangxi, Henan, Hunan, Qinghai and Shandong), 9 Chinese municipalities (Changzhou, Guilin, Hefei, Luoyang, Nanjing, Qingdao, Weihai, Zhuhai and Zhuzhou), representatives from local and provincial academies and research centers, European and Chinese experts.
During the event, among the many speeches, Ma’am Tong Guichan, Director of the Division of International Cooperation of MoHURD, affirmed the crucial importance of sustainable development of Chinese cities and the strong support of MoHURD to EC Link Project; Mr. Wang Daorong, Deputy Director General of Hefei Municipality, stated the great commitment of Hefei City to develop more environmental sustainable projects and the great importance of events like Hefei ICL where Chinese cities have the opportunity to share their experience with multiple European ones; Mr. Andrea Claser, Team Leader of EC-Link Project, stressed the full commitment of the Project to be a key component for Chinese and European cities in order to share mutual experiences and hopefully develop long term cooperation; Mr. Florian Steinberg, Senior Urban Planner – EC-Link, provided important insights and specific examples about ongoing Chinese urban renewal and revitalization.
During the three days gathering, European and Chinese representatives have been sharing experiences and knowledge with the intent to create the so called City Network Units (CNUs); these new established working groups of Chinese and EU cities (CNUs) will work together to adapt selected practices/procedures to the Chinese urban context, so to allow an effective know how transfer.
In upcoming months, European and Chinese cities will work together with the intent to develop joint technical teams meant to be the baseline of long term cooperation programs and technology exchange in multiple areas such as: water governance and integrated river basin, zero landfill policy, renewable energy from bio-waste, urban storm water management, district heating from co-generating power plants, waste water treatment for the removal of harmful pollutants, municipal solid waste management, and many others.
During 2016, Hera continued to implement the city centre separate waste collection project, consisting in the construction of mini underground drop-off points for glass and organic waste, and simultaneously starting door-to-door separate waste collection district by district, and other collateral actions such as custom collection for businesses, separately collecting crates (wood and plastic), plastic packaging, paper non-separated waste and to upgrade existing underground drop-off points for disposal of cardboard and non-separated waste.
