How modern, automated waste collection can boost recycling, cut costs, and save energy

Traditional waste collection is costly, inefficient, and harmful to the environment. Envac’s automated system reduces costs, cuts emissions, and boosts recycling. With Energy Optimisation, Power Balancing, and End-user Engagement, cities like Stockholm and London are already benefiting. Discover how automation is shaping a cleaner, more sustainable future.

Rethinking Waste Collection: A smarter, greener future

Today’s traditional manual waste collection faces several pressing challenges. High labour costs are a concern, as the process is labour-intensive and demands significant human resources. Workers are exposed to health and safety risks, including handling hazardous materials, heavy lifting, and potential accidents. Environmental impacts are also severe, with frequent refuse lorry trips contributing to air pollution and increased carbon emissions, particularly in densely populated areas. The process adds to noise pollution and traffic congestion, disrupting urban life. Inconsistent service may result in missed collections or waste accumulation, while manual systems struggle to scale with population growth, leading to inefficiencies. Lorries often operate with irregular waste loads, resulting in underutilised capacity and increased costs. These issues underscore the urgent need for smarter, more efficient waste management solutions.

Envac’s automated waste collection system offers a transformative approach, tackling these challenges with a forward-thinking, efficient solution. By automating waste collection, the system eliminates the need for labour-intensive tasks, reducing operational costs and improving worker safety. The automation significantly reduces the frequency of refuse lorry trips, cutting carbon emissions and air pollution in urban areas. This, in turn, alleviates noise pollution and traffic congestion, creating a more harmonious urban environment.

The 3-in-1 concept for smarter waste management

Envac’s 3-in-1 concept—comprising Energy Optimisation, Power Balancing, and End-user Engagement—further enhances efficiency and sustainability:

  • 1. Energy Optimisation: The system is designed to use energy more efficiently, minimising power consumption and lowering operational costs.
  • 2. Power Balancing: By monitoring and adjusting power usage in real-time, energy spikes are avoided, leading to cost savings and reduced environmental impact.
  • 3. End-user Engagement: The Envac ReFlow app fosters recycling and waste reduction through an interactive platform. Users receive feedback and guidance to refine recycling habits, ensuring a more seamless and effective waste management experience.

Envac’s impact on recycling and efficiency across cities

  • Stockholm Royal Seaport: Envac ReFlow has significantly reduced general waste while improving resident satisfaction through features such as error reporting, inlet guides, and recycling tips.
  • Sweden’s Skarpnäcks and Eriksbergs Facilities: The new EAP4 (Envac Automation Platform version 4) has delivered substantial energy and cost savings.
  • Barking Riverside, London: Since adopting Envac’s Automated Waste Collection System, recycling rates have surged to over 41%, compared to just 12% for similar flatted properties in London. With 460 Envac inlets replacing the previous 19,000 bins, the efficiency gains have been remarkable.
Barking Riverside in London has seen consistently high recycling rates of over 41% since the introduction of AWCS.

The case for automated waste collection

Modern automated waste handling systems like Envac’s offer a transformative response to the challenges of traditional waste collection. By cutting labour costs, minimising environmental harm, and improving operational efficiency, these systems enable higher recycling rates and contribute to a cleaner, healthier urban environment.

The integration of Envac’s 3-in-1 concept ensures a comprehensive approach, enabling sustainable waste management while actively involving residents in the process. As demonstrated in cities like Stockholm and London, automated waste systems deliver significant economic savings, increased recycling participation, and improved quality of life. Investing in automated waste collection technology goes beyond logistics—it fosters a circular economy, benefiting communities and the planet. Embrace the future of waste management with Envac and join the movement towards a sustainable tomorrow.

Waste disposals point

The indoor waste disposals points can be placed on each floor or in the entrance hall.

Air inlet valve

The Air inlet valve let transport air into the system at signal from the control system.

Waste inlet

The waste inlets are connected to an underground pipe network that transports the bags from the inlets to the waste collection station.

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.

The sealed system removes foul smell and can be placed close to residential buildings, making littering a thing of the past. Our system reduces waste collection traffic and the noise, emissions and pollution associated with it by up to 90%, making city life greener, cleaner and more sustainable.

Vertical storage chute

This is where the bags are stored until the chute is reaching full level. Sensors in the chute send a signal to the waste collection station and an emptying circle is started.

Powerful fans, in the station, create an airflow in the pipes. Transport air is let into the system.

Pipes

The bags are transported to the collection station at 70 kph.

Litterbins

Self-emptying litterbins can be connected to the system.

Waste collection station

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.

Containers

When a container is full, it is detached from the compactor and loaded onto a truck for transport to the recycling center, where it is emptied and returned.

Fans

Powerful fans generate the necessary airflow in the pipes to transport the waste to the terminal.

Air outlet

The transport air is filtered before release, making it cleaner than when it first entered the system.

Cyclone

In the cyclone, the transport air is separated from the bags, allowing the bags to slide toward the compactor under the combined effect of the cyclone’s and gravity.

When the waste reaches the compactor from the cyclone, a vertical tray pushes it into the container to make the most of its capacity.

Diverter valve

Once the waste reaches the terminal, it is directed to its corresponding cyclone through the diversifying valve. So, each type of waste will reach the container for its fraction.

Available 24/7/365

The resilient system is part of the smart city’s infrastructure and available 24/7/365.
