The indoor waste disposals points can be placed on each floor or in the entrance hall.Air inlet valve - Will let transport air into the system at signal from the control system.Outdoor disposal point. The inlets, one for each type of waste/reclables, are placed close to the building for comfort. The easier it is to dispose of sorted waste, the more will be sorted. Vertical storage chute - This is where the bags are stored until the chute is almost full. Sensors in the chute send a signal to the waste collection station and an emptying circle is started. Valve - opens on signal when system is pressurized.The waste inlets are connected to an underground pipe network that transports the bags from the inlets to the waste collection station. The bags are transported to the collection station at 70 kph.Powerful fans create an airflow in the pipes. The waste collection station is located as far away as possible from the apartments, ideally close to a main road.

With Envac there is no longer need for trucks to drive up to each building to collect household waste, it is collected at the terminal building only.

The area becomes less noisy, the street environment safer and the air cleaner.
The resilient system is part of the smart city’s infrastructure and available 24/7/365.Diverter valve - directs the bags to the correct cyclone and container. The transport air is properly cleaned and filtered before released.Full containers are taken to the recycling center and returned empty.Self-emptying litterbins can be connected to the system. Cyclone - The transport air is separated from the bags.

Smart and clean waste inlets

The only user interaction with our system is at the waste inlet, where users leave their waste.

The waste inlets are conveniently installed within 30 metres from residential or office buildings, with separate inlets available for each different kind of waste.

The users sort their waste at home and dispose of them, in bags, in the respective units on their way out to work, see friends or the gym.

By making waste sorting as easy as possible, we are able to encourage recycling and support a circular economy.

Unlike traditional waste rooms or bins, our inlets are hermetically sealed, which minimises smells, reduces mess and cuts the risk of attracting vermin.

Less traffic, less emissions with Envac

This is a clip from “Discover the Envac system”, a comparison between Envac and traditional waste handling regarding traffic and emissions.

Going underground

All Envac waste inlets connect to an underground pipe network. The emptying cycle is carried out at pre-programed times or, through sensor technology, when the units are full.

The waste is transported through the pipe network at speeds of up to 70 kph using negative airflow, which sucks the bags to a waste collection station that is generally located on the periphery of a development – up to 2km away.

Emptying the waste of an entire development takes only minutes per waste stream. Unlike traditional waste collection, which is situated aboveground and exposed to the elements and extreme weather, waste collected using Envac is weatherproof, as it is stored and handled underground.

As the collection station is situated away from busy urban areas, it reduces the amount of traffic associated with multiple trucks, making multiple daily collections in and around narrow streets a thing of the past. In turn, this reduces traffic jams and cuts noise and air pollution.

Using the Envac inlet

The RFID tag is part of a smart feature that enables the provision of data-driven waste collection insights. The cardboard inlet is a recent development. Video from our installation in Bergen, Norway.

Next stop: the collection station

All the waste streams are transported in one single pipe network. Each waste stream is emptied separately and directed into the corresponding waste container at the collection station. The air used for transportation is cleaned through an industrial filter before it is released from the building.

Once a container is full, a standard collection vehicle takes the container away for the waste to be processed. This single collection – as opposed to the multiple daily collections required by traditional methods – reduces waste-related heavy traffic and the associated carbon emissions by up to 90 per cent.

It also means that the Envac automated waste collection system can be used to help reach the United Nation’s Sustainable Development Goals and create a greener planet.
