Foreign R&D teams use ultrasonic sensors to recycle e-waste

Abstract:The Malaysian R&D team has successfully developed a smart e-waste recycling bin that uses ultrasonic sensors to detect its state.When the smart bin fills up with 90 percent of the e-waste, the system automatically sends an email to the relevant recycling company, asking them to empty it.

The U.N. expects to discard 52.2 million tons of e-waste worldwide by 2021, but only 20 percent of that can be recycled. If such a situation continues until 2050, the amount of e-waste would double to 120 million tons. In Malaysia, 280,000 tons of e-waste were produced in 2016 alone, with an average of 8.8 kilograms of e-waste per person.

There are two major types of electronic waste in Malaysia, one coming from industry and the other from households. Since e-waste is a regulated waste , under the Malaysian environmental decree, the waste must be sent to government-authorized recyclers. Household e-waste, by contrast, is not strictly regulated. The household waste includes washing machines, printers, hard drives, keyboards, mobile phones, cameras, microwave ovens and refrigerators, etc.

To improve the recycling rate of household e-waste, a Malaysian R & D team has successfully developed a smart e-waste recycling bin and a mobile phone app to simulate a smart e-waste management system. They converted ordinary recycling bins into smart recycling bins, using ultrasonic sensors (ultrasonic sensor) to detect the state of the bins. For example, when the smart recycling bin fills up with 90 percent of its e-waste, the system automatically sends an email to the relevant recycling company, asking them to empty it.

”At present, the public is more familiar with the ordinary recycling bins set up in shopping malls or special communities that are managed by the Environment Bureau, MCMC or other non-governmental units. Usually 3 or 6 months, the relevant units will clear the recycling bin.”The team wants to improve the efficiency and functionality of existing e-waste bins, using sensors and cloud services to enable recycling merchants to make good use of human resources without worrying about empty bins. At the same time, more smart recycling bins can be set up to allow people to put e-waste in at any time.

The hole of the smart e-waste recycling bin is small, allowing only mobile phones, laptops, batteries, data and cables, etc. Consumers can search for nearby recycling bins and transport damaged e-waste by mobile phone app.”But currently large home appliances are not accepted, they need to be sent to the relevant recycling station”  

Since the outbreak of COVID-19, DianYingPu has been keeping a close eye on the progress of the epidemic, providing better ultrasonic sensors and better servicing to relevant enterprises according to the latest regulations and arrangements of the national and local governments.
