Landfill managers interested in an alternative to soil, mulch, or plastic daily covers may be interested in BioCover™ (ADC), a product designed for use on the working face of landfills. A benefit of Bio Cover is that it’s manufactured from recycled materials. These include thermally-refined wood and cellulose fibre, with a proprietary organic-based “tackifier.” In addition to savings in time and labor, this material saves money by taking up less landfill volume and saving soil.

Benefits include:

• Increased landfill density

• Less expensive than moving dirt or using tarps

• Tackifier will stick to plastic

• Reduces vectors and odors

• Fast and easy hydraulic application

• Helps control blowing litter

• May be used for hydro mulch applications BioCover is mixed at a rate of 50 lbs of the material per 100 gallons of water (see equipment manufacturer’s loading recommendations). In a typical application, the material uses 50 to 75 lbs per 1000 square foot area. Each package weighs 50 lbs and 40 bales fit on a pallet (with a truckload of 22 pallets therefore delivering 880 bales).

Mercer Motor Works specializes in the manufacture of patented self-deploying landfill tarps, daily cover and retrieving Tarp Deployment Systems (TDS). These are ideal for use as alternate daily cover on landfills and other uses. Savings in money and airspace can be realized using an alternate daily cover in place of soil.

One TDS system with a 60 by 150 ft tarp replaces approximately 167 cubic yards of cover soil (six-inch depth as required per regulation) at a cost of about four dollars per cubic yard per day or $668 per day! If you consider that the average waste density is 1,500 lbs/cu yd and with a potential revenue of $50 a ton, one TDS can save you as much as $6,263 in airspace plus $668 in cover soil (for a total daily cost savings of approximately $7,000 or $1.82 million annually (based on a five-day work week).

By covering each day’s waste in a 9,000 sq. ft. cell with six inches of soil per government regulations, a landfill operation loses 130 ft. of vertical revenue generating space (or in excess of 43,000 cubic yards) that could generate revenue of about $1.6 million each year.


One TDS-30 can deploy and retrieve several tarps of various types and sizes in just minutes with one machine and one operator, saving time and labor.

The frame is made of heavy-duty gauge steel and able to support at least three 30 ft. wide by 100 ft. long ballasted 6.5 oz. coated polypropylene tarps, with 5/16″ chain sewn in pockets. Frame legs have shoes welded on to support the TDS unit in soft or muddy ground conditions.

The TDS unit weighs around 3,000 lbs. and can easily be used in landfills with high sludge content. The engine (5 1 /2 hp Honda gas powered) and hydraulic system is of adequate size to operate the TDS machine spool that supports the specified tarps and will operate in all weather conditions.

The TDS machine comes with a manual control and a heavy-duty remote control unit for retracting and extending controls for rolling and unrolling the tarp covering system.

Tarp sizes can be custom ordered to a shorter width depending on the working face. Also, the tarps can be ordered unballasted if the working face is not subject to high winds and if the operator prefers to use a couple of tires to weigh down the tarp.

The TDS is manufactured so no fixtures or brackets need to be added to equipment. The brackets are manufactured right on the TDS unit. The blade of your equipment hooks under the bracket on the TDS unit and you are then ready to deploy or retrieve for your daily operation. The TDS can be moved and operated from D4 to D8 class bulldozers or CAT 826 size compactor.

The remote control unit has a maximum operating distance of 150 feet from the tarp machine and is easily operated by the operator inside his cab.
