HTR Balers comprise a complete range of two ram balers fitted with a unique polyester strapping system combined with a telescopic tunnel. This technology, developed by PAALGROUP, leads to an enviable combination of improved performance and lower operating costs.

LOWER OPERATIONAL COSTS…

The use of a closed chamber combined with a telescopic tunnel is the optimum method of achieving stable, uniform bales, with an exceptionally high bale density. When using the baler as a waste transfer station, the dense, even bale structure  enables transport costs to be reduced dramatically. This waste handling solution was selected by ENVIRO SOLUTIONS Inc for its Newark (USA) transfer station. To meet the customer’s precise requirements, PAALGROUP developed the HTR 300 Big Duke model for this project. This offers further reductions in operational costs, through lower consumables (polyester straps are much cheaper than steel wire) and reduced handling costs (with bales sizes of 3 metric tonnes). Furthermore, as part of the process, bales are hygienically wrapped to enable safe and clean transportation by rail wagons.

An alternative application for the baler is to install it as part of a landfill operation..By compacting the waste into high density, uniform bales, the economic life of the landfill can be extended greatly, or a smaller site can be utilised. Either way, the operational costs of the landfill can be reduced significantly. The unique liquid collection system reduces the quantity of liquid introduced in the landfill and, hence, subsequent leachate treatment costs are also reduced. This is the solution that Marseille Urban Community selected for its landfill in St Martin de Crau (France) on which 3 HTR 240 balers operate for treating unsorted Municipal Solid Waste.

Finally, the use of a polyester strap represents a significantly cheaper alternative to  expensive steel wire tying systems. It reduces operational costs whilst increasing bale density and stability. Baled material is easier to maintain than loose refuse and it requires less soil for the covering layer, thus generating further cost reductions in the plant operation.

IMPROVED SANITARY CONDITIONS…

As well as the financial benefits, these balers offer many advantages in terms of improved site cleanliness and hygiene, particularly when used in conjunction with a plastic bale wrapping system..

EFFICIENT INCINERATION...

The patented plastic strapping system offers far better compatibility with incineration than steel straps, as it will not damage the incineration plant. It is also better from a health and safety perspective in that it reduces the risk of injury to onsite staff. An important factor in the economic operation of incineration plants is the cost of storage and handling. The high density bales achieved with HTR balers reduces the space necessary for temporary storage and the square format of the bales, combined with their uniform size, eases the problem of handling and storing. COSTA MAURO Italia has equipped its Refuse Derived Fuels production site with an HTR150 baler, gaining significant temporary storage space and reducing transport costs. This baler is equipped with all necessary equipment for treating Refuse Derived Fuels from a stream of Loose/Bulk/Untreated Municipal Domestic Waste.
