Movac - Mobile Vacuum Waste Collection System
The mobile vacuum system was developed in the late 1980's, primarily for small and medium-sized areas. The third generation - Movac - has a greater capacity than it's predecessors and is designed for urban and suburban environments. Movac is a cost-effective and environmentally friendly alternative to other mobile collection systems.
Waste inlets are positioned centrally
Users throw their waste bags into readily accessible waste inlets located either indoors or outdoors. The waste is then stored in closed underground screw tanks, which are linked together with docking points by a network of underground pipes.
Docking points are located on the outskirts of a development or area
These docking points are positioned in such a way as to ensure that the vacuum truck picking up the waste causes minimal disruption by avoiding gardens, narrow streets and densely populated areas.
The tanks are emptied regularly
The underground tanks are emptied regularly depending on the amount of waste discarded and the storage capacity of the screw tanks. The vacuum truck, which empties the tanks via the docking points, creates a vacuum in the pipe system. Once this vacuum has reached a required level the waste is sucked seamlessly out of the screw tanks, through the pipe system and into the vacuum truck, where it is compressed.
The waste is weighed
When the screw tanks are emptied the amount of waste collected per tank is recorded by measuring the weight in the vehicle. This information can then be used to invoice individual property owners or companies for the exact amount of waste they produce.
The Envac solution is a long-term investment with significant financial and environmental advantages. It makes areas considerably cleaner, reduces carbon emissions and increases the sustainability credentials of the environments in which it operates.
No need for collection vehicles
As there is no longer any need to manually empty bins, waste collection vehicles no longer need to make frequent visits to the area. This reduces the amount of heavily polluting waste collection vehicles on the roads whilst creating a safer environment for residents. Resource traditionally associated with manually emptying bins can be reallocated and waste collection cycles can be made more regularly - and for less cost.
Hygiene is considerably improved for people in the area and for waste collection operatives, who no longer need to come into contact with the waste. As the system is hermetically sealed, the litter will not attract pests or insects or release unpleasant odours.
Lower operation and maintenance costs
The initial cost of the investment is offset by lower operation and maintenance costs. Contact us for a calculation of how much you could save.
Screw tanks are a new invention, which have been developed in line with the third generation of mobile vacuum systems. They further streamline waste handling and efficiently and reliably transport waste from the pipe network to the collection vehicle. The waste in the screw tank is screwed out into the pipe system, which speeds up emptying times and requires less vacuum power resulting in quieter emptying. The screw tanks can be positioned ‒ one or more together ‒ in a site-built underground concrete chamber, a basement or other free space. If no space is available, Envac also supplies complete concrete chambers with a screw tank and motor already installed. The screw tanks are available in different sizes and with different numbers of inlets.
Vacuum Truck VL-5
Our new VL-5 vacuum waste collection vehicle is more environmentally friendly and significantly quieter than previous models. The driver manages the collection process and empties the tanks from the vehicle. The waste is compacted in the truck and the transport air is cleaned before being released. The increased load capacity allows several tanks to be emptied per pickup, which reduces the number of pickups and the associated carbon emissions generated through lorry miles. The VL-5 third-generation vacuum truck has been developed in cooperation with Scania and can also be run on biofuels.
Bigger pipes allow bigger waste bags
The tanks are connected to a pipe system with a diameter of 400mm. The pipes are made of steel and laid underground at a depth of 50cm or more.
The increased pipe diameter now permits the use of waste bags up to 60 litres in size, which means that Movac can be used in restaurants and shops.
Card reader system identify the individual user
An advanced card reader system can also be used to identify individual users allowing individual waste handling charges to be levied.
This system is ideal for recycling, as the inlets can be placed closer to the user making sorting at source easier and less of a burden.
Each type of waste requires a separate inlet and storage tank of its own. Although only one pipe is used for transporting multiple waste streams from the tank to the truck, the control system ensures that each waste stream remains separated.
