Waste management is an inelegant subject to discuss, but a crucial one when thinking about national infrastructure. With a growing population, and a finite volume of resources, cities across the US begin to buckle.
Waste collection and disposal is a small but essential part of a larger societal puzzle, and a vital discussion when sustainability measures are more important than ever before. But change is afoot, as the following emergent trends in recycling and waste management effectively illustrate.
Zero Waste Programs
Zero waste programs are the bread and butter of contemporary waste management solutions, being agitated for by sustainability activists and local communities and receiving widespread corporate support. Big businesses are increasingly on-board to re-evaluate their business’ waste practices – and to seek ways to bring excess waste down to zero.
More importantly, US cities are getting on board, with municipal waste programs that promote recycling and re-use techniques to citizens and businesses alike.
1. Tech-Enabled Waste Receptacles
There are many ways in which technological is having a positive impact on waste management, but some smaller developments are set to have a significant effect on urban waste collections and cleanliness. One specific scheme has seen compactors installed in larger city waste containers, allowing a much larger amount of waste to be stored.
Sensors are used in tandem with new compactor technology to alert waste removal services when an area is ready for collection. This cuts down on fuel costs and logistical issues, through cutting down the number of waste trucks and visits needs to clear an area.
2. Domestic 3D Printing
Developments beyond the world of waste management could provide their own unique solutions to domestic waste management, as evidenced by the possibilities created by the 3D printer. 3D printers have become a commercial success at rapid speed, enabling consumers to ‘print’ their own designs and products out of a plastic compound. With the help of firewire cables and basic CAD software, product design has been effectively democratized.
But more innovation is on the way, as the prospect of directly recycling plastics into new products becomes a reality. Waste plastics could be ground up in the home and used to feed 3D printers, in order to create new items and effectively eliminate plastic landfill waste from that household.
Energy harvesting from organic sources is nothing new; water treatment facilities frequently harvest methane from solid waste extracted from sewage supply, for re-sale to the energy industry. But the methods used to harvest energy from organic processes are only getting more efficient.
The result is a concerted effort to create renewable energy from organic waste sites, through the creation of bioenergy-producing waste disposal locations that receive biodegradable waste to transform into energy.
But, even with real leaps forward in sustainable waste measures and new technological implementations, there are new challenges on the horizon when it comes to waste management. The key challenge relates to the safe disposal of ‘e-waste’, a.k.a. disposed items of electronics – of which there is a steady-growing volume.
Electronic waste items contain dangerous materials, from toxic rare-earth minerals to corrosive substances that toxify the local environment. Recycling efforts are ongoing, but there is no easy way out for recycling circuitry. This illustrates the ongoing need for urgency in the fight against unsustainable waste.
