Vacurema technology | [[Erema]]'s Vacurema systems offer modular solutions for different solutions for recycling of PET bottles. The patented process is designed for the recycling of post consumer PET bottle flakes, PET in-house waste and also PE-HD bottle flakes. Vacurema technology was first launched in 1998. | ||
Erema claims that there are currently more than 150 Vacurema systems in use around the world, producing high-quality pellets and end products with an overall capacity of over 1 million tonnes. | Erema claims that there are currently more than 150 Vacurema systems in use around the world, producing high-quality pellets and end products with an overall capacity of over 1 million tonnes. | ||

''' | '''Flexibility with input material''' | ||
Input materials with up to 1.5% moisture can be processed, no expensive pre-drying is necessary- Extruder degassing is not required either, meaning that a short extruder screw can be used and the thermal stress on the material is reduced as a result. | Input materials with up to 1.5% moisture can be processed, no expensive pre-drying is necessary- Extruder degassing is not required either, meaning that a short extruder screw can be used and the thermal stress on the material is reduced as a result. | ||
Depending on the end application the system processes PET bottle flakes, ground amorphous skeleton waste/edge trim and virgin material (also in mixtures), i.e. bulk densities of 250 to 850kg/m³. | Depending on the end application the system processes PET bottle flakes, ground amorphous skeleton waste/edge trim and virgin material (also in mixtures), i.e. bulk densities of 250 to 850kg/m³. | ||
'''Efficient decontamination''' | |||
Thanks to the patented pre-treatment of PET flakes, IV increase and decontamination are fast, reliable and energy-saving. This means that FDA quality (among other things) can be ensured for the end products produced. | |||
Surface to volume ratio for flakes is 2.5 times higher than for pellets | |||

''' | '''IV stability through vacuum treatment''' | ||
Despite varying moisture levels and different IV values in the input material, stable IV values are achieved through the patented pre-treatment method. This means, therefore, that input materials with higher material moisture levels can also be recycled. | Despite varying moisture levels and different IV values in the input material, stable IV values are achieved through the patented pre-treatment method.

''' | '''Melting under vacuum''' | ||
The patented pre-treatment at raised temperature and in high vacuum before the extrusion process removes moisture and migration materials from the feedstock in a stable process environment. This prevents any hydrolytic and oxidative decomposition of the melt in the extruder. | The patented pre-treatment at raised temperature and in high vacuum before the extrusion process removes moisture and migration materials from the feedstock in a stable process environment.

''' | '''Low thermal stress''' | ||
The very short extruder screw without additional extruder degassing reduces the thermal stress on the material through minimized dwell time. | The very short extruder screw without additional extruder degassing reduces the thermal stress on the material through minimized dwell time. | ||
''' | '''Large area ultrafine melt filtration''' | ||
The filter systems have very large active filter surfaces. This enables filtration with up to 32μm fineness at low pressure. The result is highly clean pellets. | The filter systems have very large active filter surfaces. This enables filtration with up to 32μm fineness at low pressure.

''' | '''Minimum production costs with ecoSAVE''' | ||
Electricity accounts for 38% of the costs of bottle-to-bottle recycling. Thanks to integrated ecoSAVE technology, the lowest production costs of all systems on the market. | Electricity accounts for 38% of the costs of bottle-to-bottle recycling.
