The indoor waste inlets 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 the users leave their waste. The units are typically placed conveniently within 30 meters from residential or office buildings in a group, with separate inlets for each different kind of waste. The users sort their waste at home and dispose of them in the respective units.

We want to make sorting easy to encourage recycling and thus, enable a circular economy for the future. Compared to traditional waste rooms or bins, our inlets are completely sealed, minimizing smells, mess and unsanitary conditions as well as the risk for vermin.

Touchless waste inlets – for improved hygiene and safety

Our very latest waste inlets with touchless opening. No physical contact with the door is required, it has no handle or buttons.

Installed in Monte del Pilar, Majadahonda, Spain in March 2021.

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

The waste inlets connect to an underground pipe network. The emptying cycle is done at pre-programed times or when the units are full. The waste is transported at 70kph speed, using negative airflow that sucks the bags to a remote collection station. Emptying takes only minutes per waste stream. Being underground makes the Envac system resilient against extreme weather events and with smart automation, it is reliable even in times of societal pressure. The collection station can be located as far away as 2 km from the central urban area, reducing the impact of heavy traffic, such as noise, air pollution, and traffic jams.

Using the Envac inlet

The RFID tag is part of the smart feature that allows data collection. 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 processing of the waste. This single collection reduces waste-related heavy traffic, and its carbon emissions, by up to 90 per cent compared to traditional, multiple collections – making the Envac System a key component of change for reaching the United Nation’s Sustainable Development Goals and creating a greener planet.
