Envac’s automated waste collection system for healthcare facilities offers sanitary, sustainable solutions for patients and healthcare workers alike. The system uses separate pneumatic pipes strategically placed in the hospital for soiled linen and general and infectious waste. This reduces the risk of accidents and hospital-acquired infections, ensures a more hygienic environment for patients and staff, and offers cost-saving benefits so that healthcare centres can run smoothly and cost-effectively.

Reducing the spread of infection with infectious waste collection (IWC)
Every year, hospital-acquired infections (HAIs) pose a serious risk to patient safety and cost hospitals millions. Traditional waste handling processes – whether manual or through automated guided vehicles (AGVs) – are still prone to spreading bacteria and contaminating high-traffic areas in a hospital. Automated waste collection and segregation at the source minimise human exposure to hazardous substances. Thus, direct contact with harmful materials reduces workers’ risk of health complications. It also prevents odours and potentially disease-carrying nuisances around the waste. The solution minimises the risk of cross-contamination between waste, patients, healthcare staff, and the hospital environment. For example, an Envac system installed in a French hospital transports and separates treatment of type III sharp, infectious waste with on-site sterilisations (scalpels, needles, and any metal/sharp material responsible for transmitting diseases).

Improving logistics and safety with soiled hospital linen collection
With large volumes of soiled linen and waste generated daily, hospitals must have a reliable system in place to handle collection and disposal swiftly and safely. Envac’s automated linen collection system optimises hospital logistics by reducing manual handling, streamlining waste flow, and ensuring 24/7 hygienic and secure disposal. Hospitals can improve efficiency, free up resources, and create a safer working environment by minimising staff involvement in waste transportation.
A study by KTH University in Sweden found that hospitals using closed pipe systems for soiled linen and waste disposal had significantly lower bacterial contamination levels than those relying on traditional handling methods. The findings revealed that hospitals equipped with the Envac system recorded a 49.3% lower average CFU* count and a 6.10% lower median CFU* count, demonstrating a marked reduction in microbial presence.
By automating linen collection, hospitals can streamline operations, improve infection control, and maintain a cleaner, safer environment for both staff and patients.
(*CFU: Colony-Forming Units, a measure of bacterial presence.)

Strengthening hospital reputation and ensuring regulatory compliance
Hospitals must adhere to strict infection control and hygiene regulations set by bodies such as the NHS, WHO, and local health authorities. Traditional waste handling methods increase the risk of contamination due to manual contact. Envac’s automated system reduces human involvement, minimising infection risks and ensuring safer waste disposal. A closed pipe system prevents airborne contamination, improves waste segregation, and supports regulatory compliance. Beyond compliance, a well-maintained and hygienic environment enhances public trust, reassures patients, and fosters a positive reputation. By eliminating visible waste accumulation, reducing odours, and creating a cleaner facility, hospitals can improve patient satisfaction and staff working conditions. Many hospitals are required to adopt eco-friendly waste management practices to minimise their environmental impact. Envac’s system reduces carbon emissions by replacing frequent manual waste transport with an automated collection system, cutting down vehicle movements and energy use.

Reducing costs and maximising ROI with automated waste management
Investing in Envac’s automated waste collection system delivers long-term cost savings and operational efficiency for hospitals. The system lowers labour costs by reducing manual handling, allowing staff to focus on patient care rather than waste transport. With fewer waste-related vehicle movements, hospitals also save on fuel, maintenance, and staffing expenses. A study by KTH University in Sweden found that hospitals using Envac’s closed system had significantly lower bacterial Contamination, reducing infection risks. This helps hospitals avoid costs associated with infection outbreaks, such as additional cleaning, sterilisation, and compliance measures.
Hospitals typically recoup their investment within a few years (approx. 3 to 6 years) through operational savings, improved infection control, and reduced waste management expenses. By integrating Envac’s system, healthcare facilities create a cleaner, safer, and more cost-effective environment, ensuring long-term financial and environmental sustainability.


Air inlet
Air inlet valve for the infectious waste transport pipe.

Inlet point
The number of inlet points and their location are defined by the functions of the hospital. Green pipe for general hospital waste and recyclables Red for soiled linen.
The inlets can be fitted with touchless technology that uses sensors for access control. The sensors recognize if it is waste, recyclables, laundry, or infectious waste, that is being disposed of.
Without any physical contact with buttons, handles, or panels to dispose of the waste, the spread of infections is minimized.

Infectious waste
Infectious waste is collected in a separate, hermetically sealed pipe (yellow pipe).
The closed system and touchless waste inlets minimize the spread of infections, direct transmission, and accidents.

Pipe network
The pipe network runs from the inlet points to the collection station hidden behind walls, in ceilings and in the service corridors.
This ensures that the system remains discreet and unobtrusive while saving valuable square footage which can be utilised for other purposes.

Automatically controlled
All processes are automatically controlled by Envac’s own development Envac Automation Platform (EAP).

Collection station
All materials are collected at one single point. The collection station is typically located in the technical area at the back of the hospital.
