5 Smart Cities That Are Leveraging IoT Technology for Efficient Waste Management

5 December 2018 Admin Leave a comment Blog

By 2050, 70% of the world’s population will live in urban areas. That’s according to the United Nations, which also says that by 2030, the world will host 23 megacities of more than 10 million people each. The UN’s Department of Economic and Social Affairs states, “Sustainable urbanization is key to successful development,” and sustainable urbanization rests on the innovation and distribution of data and communication technology.

The world relies on technology. The links between smart technology and sustainable development are not impractical theories of the future. They are immediate economic realities, and these links are leading to a greater demand for the Internet of Things (IoT) and more efficient, technology-directed waste management.

Smart Cities

A university study out of India titled Waste Management in IoT- Enabled Smart Cities: A Survey contends that “The new era of Web and Internet of Things (IoT) paradigm is being enabled by the proliferation of various devices like RFIDs, sensors, and actuators. Smart devices (devices having significant computational capabilities, transforming them into ‘smart things’) are embedded in the environment to monitor and collect ambient information. In a city, this leads to Smart City frameworks.”

Smart cities are defined by three characteristics:

  • They increase their operational efficiency through information and communication technology.
  • They use that technology to share information with the public.
  • They improve their residents’ welfare using data and technology.

Globally, the number of smart cities is on the rise. In 2013, the world hosted 21 smart cities. By 2025, futurists expect that number to hit 88, and North and South America will be home to 25 of those cities.

Rising human populations in urban areas are necessitating the adoption of IoT technology for processes like waste management. Smart cities are emerging not only for waste economic but also for environmental reasons.

Examples of smart city waste management tools include sensors for capacity and weight, RFIDs, and WSNs.

 

5 Smart Cities That Use IoTs for Efficient Waste Management

Here are five smart cities that are at the forefront of the movement to harness IoT technology to improve waste management.

1. Singapore

Long a leader in both technology and successful urbanization strategies, Singapore ranked first in the Global Smart City Performance Index 2017. The index graded cities on how well technology improved citizen life in four areas – mobility, health, safety and productivity.

Singapore beat the competition in each category. As early as 2016, Singapore began experimenting with smart, solar-powered rubbish bins that served as internet hotspots and came equipped with fill-level sensors. Each bin was also equipped with a compactor, which gave it eight times the capacity of a normal rubbish container. Singapore was the first smart city to implement the intelligent rubbish bin concept.

Today, Singapore hosts 7,000 public waste bins, which could exponentially increase in utility, cost efficiency, and environmental value if outfitted with sensors. To maintain its lead in smart city performance along with its reputation as one of the region’s cleanest and greenest countries, Singapore will need to keep ramping up its commitment to smart waste management.

2. Barcelona

Perhaps best recognized for its globally renowned soccer team, Barcelona was also one of the earliest cities to adopt the smart approach to urban development. According to the Financial Times, “The Spanish metropolis has long had a reputation for being at the forefront of urban technological innovation. With a municipal network of 500 km of optical fibre, free WiFi routed via street lighting, and sensors to monitor air quality, parking spaces and even waste bins, Barcelona has been at the cutting edge of testing the internet of things (IoT).”

Prior to its smart commitment, Barcelona spent 1.5 billion Euros over four years to manage waste and recycling. Today, however, the city has committed itself to reducing these costs through home-based recycling and fill-level sensors in waste bins.

3. San Francisco

As the capital of Silicon Valley, known as the cradle of the digital revolution, San Francisco surprises no one by ranking high on lists of smart cities. Perhaps that’s why San Francisco committed itself to a zero-waste goal by 2020.

Right now, it has about 20% of the way left to go towards its goal, but introducing sensors and other IoT technology could be the final boost San Francisco needs to show the world what a zero-waste urban center would look like.

4. Seoul

Already home to more than 10 million residents, Seoul proudly calls itself the “Soul of Asia.” It’s a smart soul, too, with one publication saying, “In many ways, the city of Seoul is both a blueprint ‘how-to’ guide for smart city development and a petri-dish for technological experiments.”

The city introduced smart waste solutions by installing Clean Cubes, a solar-powered waste compaction bin with embedded sensors. This solution has reduced Seoul’s waste collection costs by about 85%.

5. Seattle

Home to tech giants like Microsoft and Amazon, Seattle gives off a geeky, techno-future vibe, and it has, in fact, established a plan to become a smart city. Seattle’s smart city waste management strategies include recycling initiatives, a stable rate path, and a revamped transfer station.

This year, the city is updating its waste management plan in part to take advantage of the latest in IoT-based waste management technology.

While these cities and other technologically innovative regions are leading the way in smart development, any municipality can take advantage of IoT technology to save money, improve services, and tackle environment issues. Sensa Networks, a corporation committed to using Industrial IoT smart devices and M2M (machine-to-machine) data sharing to improve operational effectiveness and lessen environmental impact, offers solutions to facilitate better efficiencies in waste management for smart cities and others.
