Waste Disposal

   According to the World Economic Forum, China’s municipal solid waste will double that of the US by 2030.  It has been trying to grapple with waste management for over two decades now, with varying degrees of success. In 2018, new regulation banned the import of ‘foreign garbage’ from other nations desperate to offload their trash elsewhere. The legislation hit the European Union, which was exporting up to 95% of its recycled plastics to China, particularly hard. The US equally exported nearly 70% of its plastics. Despite the ban on foreign waste however, much of China’s own waste still ends up in landfills, and some of it down rivers into the ocean, according the World Economic Forum.

 


  China has strengthened the supervision and management responsibilities of the government, and introduced a number of initiatives around waste exclusion. It has imposed obligations on waste generators, has focused on enforcement, and also on product stewardship, along with the ban on foreign waste. The country has also introduced a target to reuse 60% of its urban household waste by 2025.

 

    It has also introduced some unique intelligent waste collection solutions to help. In May last year, Beijing became the latest city to enforce a waste classification system, following similar legislation in Shanghai, Shenzhen, and 16 other cities around the country. Beijing has also introduced artificial intelligence (AI) in its waste management system. Facial recognition technology has been deployed in trash bins to encourage people to recycle more.  The smart trash can pilot programme, ongoing since 2019, registers all participating residents and takes their pictures. When a resident disposes of garbage, the trash cans automatically scan their faces to identify them. Once the bin itself recognises that the user is a resident, the lid is opened, and the recycled trash is weighed. QR coded garbage bags ensure that the right trash has been dropped into the right bin. Residents are given reward credits for excelling at recycling. The move has been applauded by many.

How does smart bin work?

Features of A Smart Recycling Bin

While different smart bins offer different features, there is a core set of elements that turns a conventional trash can into a smart bin. Below we cover these core features in more detail.

Sensors

Smart bins are equipped with sensors that can detect the fill level of the bin. This information is often transmitted wirelessly over WiFI or Bluetooth, allowing waste management teams to optimize collection routesand reduce unnecessary pickups. Cameras and other sensors may also detect the type of waste being placed in the bin.

Connectivity

Smart bins are connected to the Internet of Things (IoT), enabling real-time communication between the bins, waste management teams, and central control systems. This connectivity also allows data collection and analysis.

Data Analytics

The data collected from the smart bins, such as fill levels, types of waste, and location, can be analyzed to identify patterns and trends. This information can help in making informed decisions about waste collection schedules, recycling campaigns, and resource allocation.

Notifications

Some smart bins can send notifications to waste management teams when they are nearing full capacity. This helps optimize collection routes and prevents overflow, reducing environmental impact.

Benefits of Smart Waste Bin Technology

Smart waste bins offer a huge range of benefits over conventional waste management solutions, ensuring that more waste is sorted before it reaches recycling facilities. Some of the benefits include: 

 

Efficient Waste Collection

Traditional waste collection methods often involve fixed schedules or routes, which can lead to unnecessary trips and wasted resources. Smart bins, equipped with fill-level sensors and IoT connectivity have the potential to disrupt this approach to waste management by continuously monitoring fill levels and transmitting real-time data to waste management operators.

This data provides insights into the rate of waste accumulation, enabling operators to create dynamic collection routes. Instead of collecting from bins on predetermined schedules, waste management teams can now prioritize bins that are nearing full capacity. By doing so, they reduce the number of collection trips and minimize the carbon emissions associated with fuel consumption.

   It is not the only smart solution being implemented for waste management. Elsewhere in the country, a private company is helping trash collection services deal with operational problems such as equipment disuse and the efficiency of equipment maintenance by using data analysis and the Internet of Things to gather data about garbage collection. For data collection, the firm has developed an integrated circuit which attaches to garbage bins to show their locations and inform data centres when they are full. It has also developed a database which compares individual equipment and types of malfunctions, using AI to diagnose faults and offer maintenance support.

    Some critics have expressed concern about AI and privacy. Others point out that no amount of AI can help China deal with its waste management woes, unless or until its population of nearly 1.4 billion become more proficient at waste reduction. But many believe the schemes are a step in the right direction.
