Soft Sided Waste Containers

Category: Waste Management > Waste Material Handling & Storage > Packaging
Reference # : OST No 2240 , DOE/EM-0445 Model No : Lift-Liner

The Transport Plastics Inc. Lift-Liner TM soft-sided waste packaging system includes a 25-mil woven outer polypropylene fabric shell with a 2-mil water resistant coating and a 45-mil double layer polypropylene inner liner. The outer shell is equipped with 18 lifting straps made of 2-inch polyester seat belt webbing material. The containers meet the U.S. Department of Transportation requirements for transport of low The Transport Plastics Inc. The system also includes a loading frame used to support the shell and inner liner during loading and a lifting/spreader bar. The lifting/spreader bar attaches to the lifting straps for hoisting the container from the loading frame onto a transport vehicle. A small forklift can move the empty loading frame and lifting/spreader bar. The empty bags are light and compact enough to move by hand. Dimensions of Tech Model (LxWxH): 7 X 8 X 5 ft Weight of Tech Model (lb): holds 24,000 lbs Capacity: 260 cubit ft.

Benefits

The cost of the soft-sided containers is $365 each. This results in savings of about $1,800 in container cost for each soft-sided container filled versus filing three 4 x 3 x 8 ft metal boxes or four 2 x 4 x 8 ft wooden boxes. The soft-sided containers were easier to load because of the large 7 x 8 ft open top and 5 ft depth.· Larger debris (concrete chunks, piping, etc.) loads into the soft-sided containers, resulting in less waste processing in some cases. The soft-sided containers have about three times greater volume and weight capacity than the metal boxes.· The soft-sided containers reduce void spaces and landfill subsidence. Less space is required for empty soft-sided container storage. The empty soft-sided containers are easily moved with no special equipment to the job site. Metal boxes require a forklift and flatbed truck every time more boxes are needed.

Limitations

The soft-sided containers performed well during this demonstration. There were no significant technology limitations. The minor problems are that the soft-side container can be punctured. For that event, the approach was to place a temporary patch (duct tape) over the hole if necessary and then place the container inside of another outer liner. It was no problem to lift a full container and put it back into the loading frame to re-bag.
