In the production chain of liquid food containers, the approach to sustainability is evident from the very beginning: from the choice of recycled and recyclable raw materials to the identification of the best technologies used in the transformation processes. In the processing of bottles made of PLA, rPET and any type of biopolymer, research helped to create compressors with a sustainable soul. Such as Vito Next, a range developed by SIAD Macchine impianti that, thanks to its features, lowers emissions and waste.

PLA and rPET, the advantages

The use of PLA (polylactic acid) and rPET (recycled polyethylene terephthalate) containers in the Food and Beverage industry provides enormous benefits. Specifically, bottles made from these materials:

  • Are transparent and light
  • Provide significant transportation savings
  • Greenhouse gas emissions are reduced by 80 percent
  • Comply with the SUP regulations (single use plastics directice 2019/904).
  • Are eco-friendly: they are fully recyclable and unbreakable
  • Ensure maximum safety storage in food and beverages
  • Provide energy savings due to lower blowing pressures and thus reduced power consumption

There is, then, an additional advantage to the use of PLA and rPET bottles, especially at a time of pandemic, for instance: they are single-use products that can be totally recycled once their function is exhausted, thus fitting fully into the circular economy.

VITO Next, the sustainable compressors from SIAD MI

VITO Next, or the latest line of green compressors, is SIAD Macchine Impianti‘s response to an increasing market demand for sustainability. But the range also endorses the SIAD Group’s commitment to rpoviding high-performance solutions that fully respect the environment by reducing emissions and consumption,

Together with being used for blow molding PLA and rPET bottles, VITO Next is distinguished by the following sustainability improvements over its predecessor model:

  • Product weight: minus 31%
  • Product volume: 23% reduction in footprint through design optimization
  • Specific consumption: 25% reduction in energy consumption through the use of high-efficiency electric motors, improved compressor performance through optimized dynamic fluid study of cylinders and compressor intake and discharge valves
  • CO2 emissions (due to both the improved efficiency mentioned above and optimization of the production process): minus 25%
  • Noise: reduced due to soundproofed inlet filter option
  • Powder coating: environmentally friendly, as it does not contain heavy metals
  • Material reduction: no cement and lead inside the base.
  • Vibration containment, thanks to ‘optimization of vibration damping mounts and drive belts that offer advantages in terms of reliability and operational continuity (less maintenance)

Food, beverage and cosmetics

PLA or rPET bottles and containers ensure maximum food safety. In particular, the latest generation of compressors, in the context of blowing, comply with the international ISO 8573 standard: the air used is totally oil free and the presence of moisture and dust is kept to a minimum.

For this reason, PLA or rPET bottles made with SIAD Macchine Impianti’s VITO Next compressors prove to be flexible and the best solution to contain:

  • Still and sparkling water
  • Soft drinks and energizers
  • Food oil
  • Vinegar
  • Milk
  • Beer, Lager and Cider
  • And more generally all liquids used in the food industry

Not only that, their strength and hardness characteristics also make them attractive for products that are not necessarily food, such as perfumes, cosmetics, and cleaning materials.
