Mobile Vacuum System - Movac Brochure

The third generation mobile waste system from EnvacMovac – mobile vacuum system2Since the early 1960s, Envac has special-ised in the development and installation of automated, underground waste collec-tion systems based on vacuum technol-ogy. Envac installed its first system back in 1961 at Sollefteå hospital. The mobile vacuum system was developed during the late 1980s as a complement to Envac’s station-ary vacuum system. Since then, thousands of resi-dential areas, particularly in the Nordic countries, have been enhanced with Envac’s mobile vacuum systems. This third generation of mobile vacuum systems now takes the development of a sustainable waste collection service a huge step forward.Two new featuresThe new Movac system consists of two main com-ponents: The new, third generation’s mobile vacuum vehicle, the VL-5 and the screw tank concept. These new features ensure a remarkably efficient and envi-ronmentally-friendly method of waste collection in urban and suburban areas compared with all other collection systems currently on the market.Efficiency coupled with high collection capacityA key objective has been to improve collection ef-ficiency and increase user and environmental per-formance. The system’s capacity is vastly increased by connecting the VL-5, the third generation’s vacu-um vehicle, to the new screw tanks. In comparison with previous mobile collection sys-tems, emptying time is cut in half and collection ca-pacity is more than doubled.The screw conveyors in the storage tanks feeds the waste out into the pipe system. Not only is the empty-ing process faster, it is quieter too, thanks to reduced negative pres-sure in the vacuum vehicle. An improve-ment made possible by the new improved screw tanks.Quiet and efficient waste collection without physical strain3Quiet and efficient waste collection without physical strainReduced collection costs and an enhanced environmentFaster collections and higher capacity plus reduced driving and labour requirements mean lower collec-tion costs and a healthier environment.Waste from shops and restaurants tooThe system can cope with bags containing up to 60 litres of waste thanks to the increased pipe diameter (400 mm). Card reader systems can also be used to allow selective access to inlets and individual in-voicing according to usage and the type of waste.Greater opportunities for source segregationIt is possible to achieve a simple and practical sys-tem of source segregation by installing several inlets for different kinds of waste. Another option is to have just one inlet for several materials, which are separated later at a central fa-cility. This technology is used on the continent and is called Material Recycling Facility.The increased pipe diameter makes it possible for the system to handle larger waste bags.412241This is how Envac’s third generation mobile vacuum system worksThe third generation mobile waste system offers users and waste management staff a convenient and environmentally-friendly method of dealing with waste.Centrally-located chutesThe rubbish bags are placed into an inlet, which has been installed either indoors or outdoors with easy access for users in mind. The bags are stored in sealed, underground tanks that are connected to docking points via an underground pipe network.The docking points are strategically locatedWith the docking points located at a distance from residential areas, the vacuum vehicles do not need to enter narrow alleys or courtyards. Simple emptying processThe underground tanks are emptied at regular in-tervals, according to the volume of waste and the storage capacity of the tanks. The vacuum vehicle that empties the tanks at the docking points creates a negative pressure in the Movac – the processThe waste is thrown into a disposal inlet, one inlet per 1. fraction.The waste is stored below the inlet in a screw-feeder tank.2. The tank is emptied when the screw at the bottom of the 3. tank feeds the waste into the transportation pipe together with the airflow created by the vehicle. The waste is transported from the tank to the vacuum 4. vehicle at a rate of 90 km/hour.A vacuum pump on the vehicle creates the requisite 5. airflow.Before the transportation air is expelled outdoors, it 6. passes through a special filter to remove any impurities.53 5 64This is how Envac’s third generation mobile vacuum system workspipe system. The waste is effectively and sucked out of the tanks through the pipes into the container on the vehicle where it is compacted. The driver of the vehicle supervises the process and can control the order in which the tanks should be emptied.WeighingAs the waste is emptied, the amount from each tank is weighed in the vehicle and recorded. Property owners and businesses can then be indi-vidually invoiced for the waste they produce on the basis of this information.Docking points can be raised or at street level.6Yesterday’s waste managementWaste collection is one of the most im-portant services carried out by local authorities. Not only does a badly- organised system of waste collection lead to hygiene problems, it also creates a negative image for the area and town. Littering and traffic problems A well-organised system of waste collection should really be inconspicuous and available on demand, just like other infrastructures, and not governed by the accessibility of vehicles and storage bins. Conventional waste collection in towns and cities places a series of challenges on the housing, urban and working environments.Rubbish and items for recycling left exposed in bins and skips along streets and in public places easily lead to litter, unpleasant smells and hygiene con-cerns. Risk of accidents The dangers posed by refuse vehicles reversing in residential areas are a highly and frequently debated issue in many countries.Heavy and dirtyThe manual handling of bins, rubbish sacks and containers is heavy and strenuous. It also entails physical risks such as cuts, scratches and allergic reactions.7Tomorrow’s solution: Releasing the cities of a growing waste problemUnlike a conventional waste collection system, the mobile system affords many advantages:No open storage The inlet is installed in an easily accessible location for users. The waste and recycling material is stored in a closed underground tank, directly beneath the inlet. This reduces smells and litter. Enhanced working environmentPhysical strain on waste collection employees is eliminated by the fact that waste bags are placed in the inlets – gone are the days of dragging, lifting and pushing heavy bins up and down stairs, over door-steps, through courtyards and along pavements. Injuries such as cuts and scratches are no longer a concern.Valuable space is left free for more useful purposesWaste is stored underground instead of taking up valuable ground-floor space. Housing, shops or play areas can be built in spaces that would otherwise have been occupied by refuse collection rooms. And since the need for heavy collection vehicles is drasti-cally reduced, residential areas can be planned with a strong focus on efficiency and the environment.Better safety for residentsThe docking points are strategically located so that the tanks can be emptied without any disruptions to traffic. The need to drive heavy refuse vehicles into residential areas is greatly reduced, which naturally increases safety for those living there – particularly for young children playing outside.8As economic growth and volumes of waste continue their upward trend, society places increasingly higher demands on hygienic and environmentally-correct systems of waste management. We want to increase recycling rates without putting more strain on the environment or compromising the level of service for residents. Movac guarantees a better environ-ment at a lower cost and with satisfied users.Enhanced living environmentThe need to drive heavy refuse vehicles into residen-tial areas is reduced by 60 to 80 percent by planning collection routes along major thoroughfares. Less transportation means less risk of traffic jams, noise and air pollution.BiofuelThe third generation vacuum vehicle, the VL-5, has been developed in collaboration with Scania and is designed to run on biofuel too.A sustainable waste solution9Accessibility for residentsEnvac’s system offers residents accessibility and convenience. The inlets are centrally located and linked via an underground system of pipes which means residents don’t have to walk far to dispose of their rubbish and the whole area looks cleaner and tidier, with much less litter. It becomes easier to create natural and attractive areas where residents can socialise. This makes it possible to optimise the level of service, resulting in satisfied users and improved recycling.Separation of sourceThe mobile waste system is able to handle several different waste fractions at one time. The residents and businesses who use the system are provided with special pass cards or transponders for register-ing the user, time and amount and type of waste. This can then be used to further improve separation of source.Mixed packages can at a later stage be separated for recycling.Incinerable waste is sent for incinera-tion and generates electricity and heat.Organic waste materials can be decomposed to produce compost and biogas.Separation of source and recycling10Small and medium-sized areasEnvac’s third generation mobile waste system offers a highly flexible solution for small and medium-sized areas. A flexibility that enables free-standing buildings, with a dozen or so apartments, and ex-tensive areas, with hundreds or thousands of apart-ments, to be connected to the system.Older buildingsThe mobile waste system may also advantageously be installed in older buildings where there is often a cellar that can house one or more tanks. The pipe system is then connected to a docking point outside on the pavement or adjacent to the building. It is also possible in most cases to connect existing rub-bish chutes to the mobile system. Terraced housingBecause terraced housing areas are popular with young families, waste collection is often problem-atic and collection vehicles must be driven with extreme caution. Envac’s mobile system radically reduces the need for collection vehicles and is there-fore highly suitable for terraced housing areas. Number of households per inlet Envac’s calculation software calculates the size of the tank and the number of chutes required in rela-tion to the anticipated volumes of waste and sched-uled collection rate.Commercial wasteWith its larger pipe diameter (400 mm), Envac’s sys-tem is the ideal solution for small shops, restaurants and offices. It affords tangible benefits for com-mercial properties by increasing levels of hygiene at work and freeing up space that can be better uti-lised. Commercial users can be provided with special pass cards, keys or transponders for individual access to the chutes. This also allows commercial waste volumes to be registered separately from do-mestic waste.The ideal system for small and large and new and old residential areas11Essinge Udde, Stockholm – SwedenAs this is a limited residential area, Envac’s mobile system was a natural choice for household waste.

Tanks can be placed, either individually or in groups, in concrete rooms built in situ below ground level or in other free areas. Envac also has prefab-ricated, ready-built concrete rooms (SCT-PM) with a screw tank, motor and other accessories all pre- installed. The tanks are available in various sizes and optional number of inlets, which allows for greater customisation. Envac’s solutions for ac-tive dimensioning create considerable potential for achieving an efficient and sustainable system.PipesThe tanks are connected to a system of 400 mm steel pipes that are laid underground at a depth of 50 cm or more.A screw tank installed in an existing cellar.

The driver manages the entire proc-ess single-handed and controls the emptying of the tanks from the vehicle. The waste is compressed in the vehicle and the air is filtered before being ex-pelled. The emptying process is quieter because the negative pressure is lower. The increased capacity makes it possible to empty more tanks on each run, thereby reducing mileage and the amount of heavy traffic in the area.The vehicle is nor-mally a triple-axle VL-5. The vehicle in the photo was ordered specially for Trondheim in Norway.Loading capacity 8000 kgDocking time (average) 10–15 minutesDocking range 5 metresSuction distance standard 150 metresSuction distance (maximum) 300 metresNoise level, 7 metres (max) 75 dB (A)16 11 2008 Bumling ABENVAC HEAD OFFICEENVAC AB, SE- 117 84 Stockholm, SwedenVisitors: Bryggvägen 16, Tel: +46 (0)8 775 32 00, www.envac.net, info@envac.seWe have offices in the following countries.
