Durian Husk was a Waste?
The husk of durians often thrown away as waste can be recycled into energy storage devices to rapidly charge electric vehicles and gadgets.
Professors at University of Sydney Vincent Gomes and his colleagues made use of discarded husks from durians and jackfruits to make superlight, hollow materials called aerogels. The aerogels make efficient component parts for energy storing devices known as supercapacitors.
“Durian and jackfruit offer waste inedible portions that are porous and may replace high cost supercapacitor materials, such as carbon nanotubes and graphene,”says Vincent Gomes
Supercapacitors operate differently compared to conventional batteries and does not store as much energy but they can charge much faster. An example of a good use of supercapacitors is used to store energy harvested from braking systems in electric vehicles, which can then be transferred to the battery or used to provide short bursts of power for quick acceleration.
Increasing Durian Demand and Production – more Husks Waste
Assuming every 60% of of a typical durian fruit is husk, it estimated the durian husks waste produced in year 2016 has achieved 2,280 metric tons. The production of durian fruits are predicted to achieve 22,000 metric tons at year 2020 (Lee et al., 2018). Moreover, the delivery of durians have been reaching to China and Singapore, countries that have the ability to upcycle waste materials and give them a second life. The Chinese market provides a huge consumption for the durian market and it will continue to encourage more production of durians as more Chinese starts to appreciate the spikey and smelly fruit.
Growing Environmental Concerns
As the world is increasingly concerned about Global Warming and increasingly conscious about the environmental impacts of our actions, recycling and upcycling of water materials have been gaining traction. More people hope to do more but most remain passive.
