Tiger Depack: the all-in-one solution for organic treatment.

Tiger Depack has been producing technical solutions for high performance recovery for ten years.

Food waste, production waste and waste from waste treatment processes are just a few examples of the main matrices recovered by Tiger Depack’s de-packers.

Maximum machine reliability and an in-depth study of the specificity of each type of matrix to be recovered allow Tiger’s de-packers to achieve performance that significantly cuts disposal costs and is aligned with local and global environmental regulations.

From the very beginning Tiger Depack set out to fill a technological gap in organic matrix recovery, thanks to this requirement twelve years ago the first de-packager produced by Tiger Depack was able to recover up to 98% of the contents from its packaging in just 20 square metres of floor space while processing up to 15 tons per hour of waste.

Maximum final performance achieved in a single pass.

The Tiger HS20 and Tiger HS10 are 20 and 10 tonne per hour production units respectively and their footprint is comparable: 20 square metres for the HS20 and 18 square metres for the HS10.

The different hourly capacities allow the HS20 to process from 20,000 to 60,000 tons per year while the HS10 is suitable for quantities from 10,000 to 30,000 tons per year.

The Tiger HS5, on the other hand, is the smallest de-packer with its 12 square metre footprint and is suitable for quantities from 5,000 to 10,000 tonnes per year.
This model has been dedicated to specific installations where limited floor space is available.

Pre-treatment of organic matrix

In PRE-TREATMENT applications in DRY ANAEROBIC DIGESTION AND COMPOSTING PROCESSES Treated waste is generally source-separated organic and food waste
that are fed directly into Tiger’s de-packers.
The processes in this case are pre-treatment because Tiger’s units prepare the incoming waste for optimisation.
Anaerobic or dry composting processes require pre-treatment to remove the packaging and, although no liquid is required by Tiger units, a percentage of leachate or liquid is added as inoculum.

In these cases Tiger de-packagers perform a dry mode of operation reducing the solid matter from 30% -35% to 30% -27%.

In the case of ANAEROBIC DIGESTION with WET technology, the Waste Treated and the Process carried out have the same characteristics as the previous Composting/DryAD case.

Examples of organic waste are FORSU, HORECA, WASTE FOOD.
The mass performance is UP TO 95% OF CONTENT RECOVERY (organic).
Economic performance is UP TO 90% REDUCTION IN DISPOSAL COSTS

Cleaning plastics

Surplus plastics are one of the waste products produced in the largest quantities by organic waste treatment plants.
Their recovery is a specific application, this case involves incorporating the Tiger HS20 OSC into existing pre-treatment lines where Tiger’s de-packagers are used to recover the organic matter still present in the waste produced.

The recovery of organic matter from this matrix allows for mass or energy valorisation depending on whether the process is composting or anaerobic digestion.
The composition of the waste in this case is pre-treatment waste, a mixture of plastic waste with significant amounts of organic matter still present.
The mass performance is UP TO 95% OF CONTENT RECOVERY.
The economic performance is UP TO 70% REDUCTION IN DISPOSAL COSTS.

By inserting Tiger’s HS20 OSC de-packager, the surplus stock gains a higher quality and a significant reduction in overall weight.
A pre-treatment line that generates between 25%-30% of surplus waste reduces this to 5%-10% thanks to Tiger Depack’s OSC product line.
Also in this application the HS 20 OSC’s added values of low operating costs and small footprint are an additional place when it comes to insertion into already established plants.

The Tiger Depack HS 20 OSC Oversize Cleaning was inserted after the construction and commissioning of the plant and is now positioned in the pre-treatment section

The primary stellar screen shredder chain that precedes the Tiger HS20 OSC produces the two output streams under screen (destined for the dry digester) and over screen (destined for the Tiger HS20 OSC).

The Tiger HS20 OSC is fed with 8 tonnes per hour of oversize, a stream of packaging plus unwanted foreign matter, which has an organic matter content of between 50 and 60 per cent of the total dry weight.

The heavy fraction, loaded in the same digester feed belt (NT03 figxx), has a plastic percentage < 0.5 % weighed on dry matter.
Anaerobic treatment now recovers energy from the organic matrix resulting from the Tiger HS20 OSC while subsequent composting achieves material recovery.

The other lightly separated fraction has a residual amount of organic matter after treatment of 5-6% on a dry weight basis with a recovery of approximately 90%.
It is accumulated in a special section of the pit and represents the new waste of the plant.
This material consists of clean plastic without organic residue, which is dry, light and easier and cheaper to dispose of in landfill or waste-to-energy.

The waste produced by the pre-treatment section of the plant with the inclusion of the TIGER HS20 OSC was reduced by more than 50% by weight in just one step.

Tiger Depack HS20 – Dry Anaerobic Digestion and Composting Plant – Hera Ambiente – Sant’agata Bolognese

Upstream of the anaerobic digestion system of the new Hera plant, Cesaro Mac Import perfected the pre-treatment phase with the insertion of its Tiger Depack System for the treatment of surplus waste.
In particular, it installed the HS 20 OSC model to recover material fractions otherwise destined for landfill.

Tiger Depack has made it possible to extract the organic fraction still contained within the spoil (in a proportion of 90%) with an unimaginable cleanliness of the plastic material that in this way accounts for 10% of the treated spoil.
The Tiger Depack System, developed at the drawing board, tested in the field, perfected over years of work and patented by Cesaro Mac Import itself, makes it possible both to reduce the amount of material sent to landfill (and the related transport and disposal costs) and to recover the homogenised organic component that can then be sent to composting or anaerobic digestion. Tiger Depack HS 20 OSC recovers almost 100 per cent of the organic matter still trapped in plastic bags.
The special technology cleans the OFMSW from residual plastic extracting a homogenised organic matrix of a size suitable for dry anaerobic digestion, as in Sant’Agata Bolognese.
