The recycled of biodegradable plastics
The biodegradable plastics began to develop at the beginning of the 90, initially adding starch of corn to the plastic materials. Gamma Meccanica S.p.To. (with headquarters in Bibbiano – RE Italy) began in these years to manufacture the first machine to recover this type of material.
The PLA, used mainly in the sector of the packaging is between the biodegradable materials processed with machinery manufactured by Gamma Meccanica. The recycling of the PLA is a big challenge put that, if it recycles properly, this material degrades and no longer is appropriate for his reuse.
New lines GM90 and GM 105 for packaging of alimentary use
To this end, Gamma Meccanica has developed in collaboration with some of the main manufacturers of packaging of alimentary use, the lines GM 90 and GM 105, that were the most requested for the recovery of the undone of production. The results have covered entirely the needs of the customers that used these lines since they avoided the utilisation/utilization of granes quantities of virgin materials with considerable economic advantages.
Other materials that can recycle with the lines manufactured by Gamma Meccanica are the poliolefinas and the Mater-Bi biodegradable. These materials use mainly for the preparation of alimentary packagings and stock exchanges of the purchase.
The interesting is to recycle material of undone of the industrial production. A good process of recycled allows to recover the material and reintroducirlo in the process of production.
The lines of recovery for this type of applications are very specific and have specific technical characteristics, eat: the control of the temperature, the speed of extrusion, the profile of the husillo and the cooling of the granules.
The biodegradable materials are much more sensitive to the high temperatures that the conventional thermoplastic materials, especially the obtained from the corn. It is important that the material that obtain of the process of recycled keep his properties inalteradas.
During years, Gamma Meccanica has worked with manufacturers of biodegradable materials to develop lines increasingly advanced, using the experience and collaboration of the experts of this industry.
The know-how purchased has allowed to the company be a leader in the recovery of biodegradable plastics.
Technical of Gamma Meccanica will be available to treat this subject with occasion of the fair Equiplast in Barcelona, of the 14 to 18 November, Stand B280.
