Each building is to have an outdoor recycling collection site (cardboard dumpsters and recycling carts). The designer must, for projects in which this requirement cannot be met, specify what cannot be sited at the building and the recommended location that will serve as an alternate site for these services. This is to be submitted to the Office of Waste Reduction and Recycling and to Housekeeping Services for approval.

Design considerations for waste and recycling containers must be based on the building’s usage and occupancy. All containers shall be located on an accessible path of travel per the ADA and State Building Code.

Ideally, the recycling carts and dumpsters will be on the same pad and enclosure. However, in some cases it is necessary for the dumpsters (or compactors) to be located on separate pads from the carts. This page gives a variety of configurations and basic requirements. The standard design for an outdoor service area is for a recycling and trash site that can accommodate:

  • 3-6 recycling carts (residence halls require more)
  • cardboard dumpster
  • at least one trash dumpster (residence halls and high volume areas may require more than one)

A variety of programs can utilize the outdoor service areas. Along with this a variety of containers and vehicles are used to service the program. More information is given below.

Dumpsters are serviced by front load trucks. The standard size for a cardboard dumpster is 8 cubic yards. As of April 2006, the standard trash dumpster is 8 cubic yards with access via closable sliding side doors. The concrete pad for the dumpsters can be designed in a variety of configurations as long as the pad and site meet the University’s service requirements. Pads should be sloped away from rear wall and towards planned drainage routes to avoid pooling around dumpsters and carts.

The quantity, size, and type of dumpsters needed is dependent on the building use and size. When volume or special needs dictate a larger dumpster, horizontal compactors are recommended. Contact the Office of Waste Reduction and Recycling for assistance determining the size and type of container needed.

More information about the specific containers and their dimensions is listed on Waste Handling Containers & Equipment.

Also see: Needs Based on Building Use

The information in this section can be found in the UNC Design Guidelines, Chapter III. University Planning Standards, Section A. Site Design, 16. Outdoor Recycling and Solid Waste Collection Sites.

General

Side Door Trash DumpsterA standard outdoor service area consists of 3-6 recycling carts, a cardboard recycling dumpster and at least one trash dumpster. Other situations may require more than one trash dumpster, additional outdoor recycling carts or containers for grease, food waste or animal bedding. Site dimensions and configurations should be adjusted accordingly and reviewed with OWRR for approval.

Pad Dimensions

Standard Outdoor Service AreaThe pad for the standard outdoor service area must be at least 18′ deep and 27′ 11″ wide (Horizontally: 24’3″ for the dumpster section and 4′ for the recycling container section. Vertically: 8′ for the dumpster and 10′ for the truck.) Slope pad such that water does not pool around dumpsters or carts.

Elevation drawings and details for outdoor service areas must be shown on the plans.

Containers and Equipment

See Waste Handling Containers & Equipment and UNC Design Guidelines, Chapter V, Section 11170. Items which may need extra attention include (and are the responsibility of the project):

  • making sure that funds are reserved for equipment;
  • working with OWRR to ensure that the equipment is ordered, received and installed in time for occupancy; and
  • coordinating with OWRR to make arrangements for any special needs or assistance with ordering equipment.

Screen

Wall Behind Davis LibraryUsing enclosure walls, screen sites from public view with constructed elements and landscaping.  An enclosure is required for all outdoor service areas unless exempted by OWRR.

  • Consideration should be given to maintaining visibility for vehicular and pedestrian safety issues.
  • The interior and exterior enclosure walls shall match the exterior architectural finishes of the adjacent building(s).
  • Use bollards at the wall entrances by the dumpsters to protect the walls from being hit by the service truck.
  • Do not install any piping, equipment, utility vaults or access hatches inside the outdoor service area enclosure.
  • All walls should meet current building codes.

The sample drawings for outdoor service areas and dumpster pad only give the recommended wall height (7′ to screen dumpsters and 4′ to screen carts). The Screen Wall page gives examples and information regarding brick walls that can be used to screen service areas.

Gates

OWRR prefers enclosures WITHOUT gates. Gates cause additional safety, maintenance, and operational considerations. In areas where gates are required the following guidelines are to be considered:

  • Gates must be safe and easy to operate (lightweight, no pinch points, one-person operation).
  • Gates may be used to screen dumpsters from pedestrian and vehicle view, while allowing housekeepers and other users to see inside for safety purposes.
  • Gated enclosures should have easy pedestrian access to sides of trash dumpsters and front and back of cardboard dumpsters.
  • Gates should be low maintenance (example: paint, low stress on hinges, etc.)
  • Enclosures should have a level entryway to allow for support at gate’s opening ends (for safety and maintenance).
  • Gates shall close all the way and latch in the both the closed and opened positions.
  • Gates and enclosures shall allow easy truck access (room for mirrors and for the gates to open more than 90 degrees).
  • Gates shall have intermediate posts instead of large, bi-fold spans.
  • Have catches for the rods that don’t have pinch points.
  • Gates should conform to a campus aesthetic standard if possible (color, style) for consistency’s sake and ease of maintenance.

Placement and Access

Do not use the loading dock of a building for the dumpster location. The service area enclosure shall be located adjacent to the service drive and loading dock of the building. The Waste Handling Vehicles page gives dimensions for all OWRR service vehicles.

Position the dumpster pad such that the truck can approach the containers head on. To do this, take into consideration the turning radius, truck length, and angle of the approach.

Concrete Information

The pad should be a minimum of 3,000 PSI concrete, with #4 bars at 12″ on center each way, and 6″ thick. Pour the pad on compacted earth with a minimum base of 4″ Chapel Hill gravel.  These are minimum requirements. Final structural design of pad shall be based on project requirements.

Bollards

Bollards at DumpsterBollards at dumpsters areas are to be 6″ in diameter and filled with concrete.  These should be located 12″ from the center of the bollard to the rear of the pad (or screen wall). The bollards shall be 6′ 6″ in total length with at least 2′ set in reinforced concrete. Finish the bollards with one coat exterior metal primer, and two coats exterior yellow. For bollard placement, see sample drawings.

Ramp

There MUST be a ramp at least 5′ wide for access to the recycling containers. Also see UNC-Chapel Hill Design Guidelines Chapter V: 02450 Walks – Steps and Ramp Construction.

Drainage

The floor of the enclosure (or the pad) shall slope 1/8″ per foot to allow rainwater and other liquids to drain off without pooling. Enclosure walls shall have weeps evenly spaced around the bottom edge to allow for drainage. These weeps and the grade of the floor shall direct to the run-off into landscaped areas rather than onto concrete sidewalks and driveways.

Do not locate grease pit/traps for cafeterias inside the outdoor service area enclosure. If a grease pit/trap is necessary for the building, it shall have an enclosure separate from the outdoor service area enclosure. The two may share a common wall, but they shall have their own enclosure walls and separate entrances.

Lighting

Provide sufficient lighting for the security of the personnel and campus community using the site at night and during the early morning hours. Provide adequate illumination inside and outside the enclosure and on the normal routes to/from the adjacent building(s). Solar power and motion and daylight sensors may be used.

General

CompactorIdeally, the recycling carts and trash and cardboard dumpsters will be on the same pad and enclosure. However, the quantity, size, and type of dumpsters needed is dependent on the building use and size. When volume or special needs dictate a larger dumpster, horizontal compactors are recommended. These may be used for trash or cardboard.

When there is adequate volume of both trash and cardboard but very limited space, a split body compactor may be considered.

CompactorDo not use horizontal compactors at residence halls without written approval of OWRR and Housing and Residential Education.

Many locations requiring compactors also require containers for grease, food waste or animal bedding. Site dimensions and configurations should be adjusted accordingly. Contact the Office of Waste Reduction and Recycling for assistance determining the size and type of container needed.

Pad Dimensions

Compactor Open RolloffThe pad for a 30-cubic-yard horizontal compactor should be 12′ wide and 40′ long. Additional space may be needed for the electrical unit. Elevation drawings and details for outdoor service areas must be shown on the plans.

Click on the image for a sample drawing of a pad for a Horizontal Compactor.

Containers and Equipment

DimensionsWe consider compactors part of the building and require that the design team spec the equipment into the project.  This information should be included in Section 11170 Solid Waste and Recycling Handling Equipment. We recommend that the design team work with an equipment supplier early in the design process.

Lenoir Hall CompactorThe Waste Handling Containers & Equipment page provides detailed compactor information including:

  • Style
  • Standard capacity
  • Dimensions
  • Charge box requirements
  • Performance data
  • Hydraulic
  • Electrical
  • Building wiring info
  • Required features
  • Paint info
  • Possible suppliers
  • Cost

McColl Building CompactorAlways try to use the largest container possible for the space, thereby minimizing the number of times the container has to be pulled to the landfill or recycling facility.

Items which may need extra attention include (and are the responsibility of the project):

  • verifying that the equipment features are appropriate for the setting and use;
  • making sure that cost of the equipment is included in the project;
  • making sure equipment is ordered and installed in time for occupancy;
  • training staff as to the operation and maintenance of the equipment, and
  • coordinating with OWRR to make arrangements for any special needs or assistance with ordering equipment.

Screen

Wall Behind Davis LibraryUsing enclosure walls, screen sites from public view with constructed elements and landscaping.  An enclosure is required for all outdoor service areas unless exempted by OWRR.

  • The interior and exterior enclosure walls shall match the exterior architectural finishes of the adjacent building(s).
  • Consideration should be given to maintaining visibility for traffic and safety issues.
  • Gates are not to be used for reasons of safety, maintenance, and operational issues.
  • Use bollards at the wall entrances by the dumpsters to protect the walls from being hit by the service truck.
  • Do not install any piping, equipment, utility vaults or access hatches inside the outdoor service area enclosure.
  • All walls should meet current building codes.

The sample drawings for outdoor service areas and dumpster pad only give the recommended wall height (7′ minimum). The Screen Wall page gives examples and information regarding brick walls that can be used to screen service areas.

Placement and Access

Compactor From DockIn almost all situations, the compactor should be located on ground level adjacent to the dock (see photo right). Doghouses and feeder chutes may be needed to feed materials into the compactor. Check with OWRR and an equipment supplier for guidance on this. The Waste Handling Vehicles page gives dimensions for all OWRR service vehicles.

Position the pad such that the truck can back straight up to the compactor. To do this, take into consideration the turning radius, truck length, and angle of the approach.

Issues related to placing compactors ON the loading dock include the height of the dock and the placement of the control box. The truck may not be able to service containers placed on docks higher than 42″. Also, a wench may be necessary to pull the rest of the way onto the dock.

Concrete Information

The pad should be a minimum of 3,000 PSI concrete, with #4 bars at 12″ on center each way, and 6″ thick. Pour the pad on compacted earth with a minimum base of 4″ Chapel Hill gravel. These are minimum requirements. Final structural design of pad shall be based on project requirements.

Building Wiring Information

Compactor Electrical PageCompactor Electrical PageThe control box will be surface mounted. The disconnect box must be located near the control box and should be wired for a 10 HP 3 phase motor with 480 V.

Electrical detailed information (from Marathon Equipment Co.). Click on images for full page views.

Install operation switch sufficiently far from compactor to maintain safe operation. Do not place where broom handles or other devices can be used to “lock” the switch in the operating position.

Ramp

There MUST be a ramp at least 5′ wide for access to the recycling containers. Also see UNC-Chapel Hill Design Guidelines Chapter V: 02450 Walks – Steps and Ramp Construction.

Drainage

In the event of a failure in the compactor seal or other malfunction, the site must be sloped for drainage into a drain located out from under the container. Drain size should be consistent with UNC standards. Pipe drain into sanitary sewer system and provide an oil water separator system.

Provide an anti-freeze hydrant for wash down purposes at all sites using compactors.

Usually compactors are in high traffic service areas. The following is provided in case an enclosure is used:

  • The floor of the enclosure (or the pad) shall slope 1/8″ per foot to allow rainwater and other liquids to drain off without puddling.
  • Enclosure walls shall have weeps evenly spaced around the bottom edge to allow for drainage. These weeps and the grade of the floor shall direct to the run-off into landscaped areas rather than onto concrete sidewalks and driveways.
  • Do not locate grease pit/traps for cafeterias inside the outdoor service area enclosure. If a grease pit/trap is necessary for the building, it shall have an enclosure separate from the outdoor service area enclosure. The two may share a common wall, but they shall have their own enclosure walls and separate entrances.

Lighting

Provide sufficient lighting for the security of the personnel and campus community using the site at night and during the early morning hours. Provide adequate illumination inside and outside the enclosure and on the normal routes to/from the adjacent building(s). Solar power and motion and daylight sensors may be used.

General

Rolloff Container - 20-yardTheatres, art studios, and maintenance shops often produce bulky waste that cannot be collected in front load dumpsters. Open top roll-off containers must be sited in some instances.

Examples of buildings that generate bulky waste such as construction debris, pallets, scrap metal, etc. on a regular basis may include theatres (set striking debris) and maintenance shops (Athletics, Facilities Services, Cogeneration, etc.). Other areas utilize rolloff containers seasonally or temporarily for special events such as festivals, sporting events or student move-in and move-out.

Site dimensions and configurations should be adjusted accordingly. Contact the Office of Waste Reduction and Recycling for assistance determining the size and type of container needed.

Pad Dimensions

Compactor Open RolloffThe pad size will be dependent upon the container selected. Always try to use the largest container possible for the space, while still allowing easy loading of materials by workers. For a 20-40 cubic yard rolloff container, the pad should be 12′ wide and 40′ long. Elevation drawings and details for outdoor service areas must be shown on the plans.

The grease collection contractor supplies these containers.

Note: Grease collection containers with a capacity of 55 gallons or more may require a spill protection plan. Consult with the UNC Department of Environment, Health and Safety for more details.

Placement and Access

  • vehicle width (with mirrors) and length;
  • turning radius;
  • ability to wheel carts to the truck from the recycling site.

Ramp
