How to recycle PP raffia efficiently?
Post-industrial recycling of PP raffia, woven sacks, tapes, non-woven/woven, FIBC and jumbo bags could be challenging at times for some producers due to the following reasons:
1) Difficult to process in one single step due to size and strength of the material waste (ex. FIBC, jumbo bags and bulk bags).
2) When recycling has to be done in several processing steps, it is not cost-effective for the producers in terms of labor, electricity, and occupying too much factory space.
3) Difficult to retain material property (strength and elasticity) after recycling in which the material degrades excessively and therefore, the reusability of the recycled pellets back into the production lines is relatively low.
4) Difficult to process heavily printed woven bags (for example AD*STAR bags and cement bags) as the degassing and screw design of the recycling machine is not ideal for this type of material with extra amount of ink.
5) Comparing to film waste, it is more difficult to cut and feed raffia waste consistently into the recycling machine for its strength and size. Usually, it has to be done in separate steps.
Elant company developed one step recycling machine provides solutions to the above problems with the following features:
1) One step process with shredder + extruder + pelletizer all integrated into one simple, easy to operate recycling machine.
Instead of having a separate off-line crusher or shredder, this system integrates the shredder with the extruder, allowing a more automated and consistent feeding of the material, which results in stable output and higher quality of recycled pellets.
2) Low processing temperature in the single shaft shredder:
This gentle and short, one-step process ensures minimal material degradation, which allow producers to re-use a higher percentage of the recycled pellets back into the production lines and still meeting the industrial standards (for example, strength and elasticity of jumbo bags and bulk bags for US exports).
Instead of using an agglomerator or a cutter-compactor which processes the material at a higher temperature for a longer period of time, the gentle yet powerful single shaft shredder cuts the raffia waste within a short time at a much lower processing temperature. This helps to maintain the property of the post-industrial waste material as close to new material as possible.
3) Specialized degassing and screw design for processing heavily printed bags:
The optimal screw design can eliminate the problem of material coming out from the degassing (venting) area almost completely, so the machine can operate at full speed with stable production. Efficient degassing is another key factor to ensure the pellets are solid (instead of fluffy and hollow in the middle).
