Pelleting

THE PELLETING MILL

The main advantages of densified fuels, compared to non-densified ones are the following:

An increased bulk density (from 80-150 kg/m3 for straw or 200 kg/m3 for sawdust to 600-700 kg/m3 after densification), resulting in lower transportation costs, reduced storage volume and easier handling.
A lower moisture content (humidity <10%), favouring a long conservation and minor losses of product during the storage period.
An increased energy density and more homogeneous composition, resulting in better combustion control possibilities and thereby higher energy efficiency during combustion .

Below is a small selection of waste products “feedstock” used in pelleting

Wood waste including sawdust, pallets, salvaged value add wood, wood chips, ….
Hay, wheat, Hemp, harvested Cannabis, Corn Stocks & Cobs, Corn Stover, Rice Husks
Sorted Municipal Solid Waste (glass, metals, organics and plastics removed).
Animal Manure, Human municipal wastewater sludge (bio-solids).
Waste fabrics from clothing manufacturing and recycling.
Olive Pomace.
Grape Marc / Pomace.
Bagasse.
Leaves, Brush Clippings, Grasses.
Standing trees infected with Parasites (no marketable value as lumber).

Waste stream is delivered to the pelleting facility.
The waste is sent through a Hammer Mill to homogenise the product.
- The waste needs to be uniform, and well blended.
Homogenised product is fed to the dryer.
- The dryer removes any excess moisture above 10%.
Stable, dry, homogenised waste is sent to the shaker table.
- The Shaker table removes “fines”, which are reused in the process.
The product is now sent to the Pelleting line.
- The dry, homogenised waste is compressed under pressure to extrude a stable pelleted product.
Pellets are cooled and sent to the bagging line.
- Final product is Bulk Bagged, and transported to market.

Most advanced countries are deploying highly efficient Biomass Boilers/Heaters to replace fossil fuels.
Although this move is admirable, it in fact creates another non-sustainable draw on dwindling natural resources.
Most, if not all heating pellets are derived from Virgin Forests. Cutting down large tracks of Virgin Forest is not a sustainable practice, as many of these forest are not re-planted, and or will take a generation to reach a marketable size.
Most countries are now banning all Virgin Forest pellets.
There is a deficit of heating pellets in the European market that exceeds 12-million/ tons/ year, and growing.

Below is a small selection of markets served

Heating – pellets are used to efficiently fire biomass boilers, creating heat and electricity.
Bedding – safe bedding for animals, providing higher absorption rates than traditional bedding.
Absorption – used in the oil & Gas industry (safer, smarter, and more cost effective than chemical absorbents).
Fertiliser – slow release, higher concentrate of beneficial nutrients, safer and more cost effective than synthetic chemical compounds.
Hemp – produces a higher yield of CBD oil upon extraction.
Animal Feed – processing a higher nutrient value, organic, safer, and healthier for the animal (sustainable husbandry practices)
