Underground vacuum cleaners, the future of smart waste management?

While sweeping, noise pollution and odor-related hazards complicate conventional waste management systems in cities around the world, high-tech underground trash cans offer a smart solution to the problem.

Last June, Evac installed its bespoke underground waste collection network system in Maroochydore City on the Sunshine Coast.

The Swedish underground waste collection specialist is responsible for installing high-tech waste inlets that can suck municipal waste underground from apartments and commercial buildings at a speed of 70 km / h through an underground network of pipes, thus eliminating the need for waste collection trucks.

The new system is intended to beatify the cityscape as well as contribute to overall cleanliness as it will eliminate the need for wheelie bins, which are seen as a nuisance especially in summer due to their tendency to overflow. Envac’s smart waste solution can also help prevent traffic congestion while helping to reduce carbon emissions from daily waste collection rounds.

Emptying roadside trash cans via high power vacuum only takes a few minutes unlike the hours spent by waste management fleets, the high pressure vacuum system allowing for a durable and fast waste collection operation.

In the case of Maroochydore, a Queensland-based trade hub, Envac facilitated the construction of an underground pipeline network that spans more than 6 km, funded in part by a $ 21 million fund.

So far, the project is underway, with several arrivals of garbage cans and collection stations as well as the first parts of the underground piping, intended to treat organic, general as well as recyclable wastes, having already been completed.

The futuristic waste system works as follows: Waste deposited by individual entrances through city-wide collection points falls into a sealed underground compartment. When the vacuum pump is activated, this waste is sucked up through a network of pipes and delivered in compactors contained in the central installation concerned, awaiting collection for recycling.

It will be the first automated underground household waste system of its kind to be built in Australia.

If the program is successful, other cities could adopt this smart waste solution, with plans for the possible expansion of the pipe network that potentially exists in the maps. Talks with other Australian councils, governments and developers of larger blueprint communities have already taken place.

Globally, Envac’s penetration rate is increasing, with similar projects being implemented in Seoul, Stockholm, Beijing, London, Hong Kong and Beijing.
