PyraSied values people and the environment and we think this is very important. We would like to tell you more about our vision of plastics and the environment...
At PyraSied, we work with the most beautiful plastic there is, acrylic (also known as Plexiglas). Acrylic exists only 80 years, PyraSied nearly 40 years. The objects we have made back in the days are saved and are still in a good condition. There are some scratches on the material due to falling over or usage, but it is not yellowed, not cracked and not warped. If you take the characteristics of the material into account, you can use acrylic for over 100 years! Perhaps people will dig up original acrylic products from the first plastic era over 10,000 years. With the inscription: PyraSied2016. Plastics are great, the mankind might be less great …
Because when you’re talking about Performance Plastics (plastics such as acrylic that are deliberately developed for long-term function) or One-time-use plastics (for example, in the supermarket, and disposable after a single use), both plastics are in composition very stable with a long service life. It is therefore highly undesirable that these materials come into the environment through unintentionally human activity and then remain there for a long time. Still, this happens a lot. It is therefore very important that the plastics are always recycled and re-used.
What does PyraSied do and does not do when it comes to the environment?
Frequently Asked Questions
- Firstly, we would like to show everyone what plastics are intended for and what not
- We advise our materials only for durable applications
- We strive to sell and use materials as smart as possible where is the least residual waste
- For this we have purchased special software that can make sure that we make optimal use of the material
- We sell residues to schools and fablabs for a small price or we use them as samples
- That what is left (the residual waste) will be recycled completely
- We have clear and white Greencast® acrylic on stock in our warehouse. This is 100% recycled cast acrylic
- We advise customers, schools, universities and fablabs about how to use our materials, the characteristics, application possibilities and the environment
- We work together with small manufacturers so we can easily produce customer-specific acrylic to produce exactly what is needed for a project
- We drive trucks region wise to our European suppliers to pick up our materials and bring them to our warehouse
- We will generate our own solar power in 2018 and our newest warehouse of 2000m2 will be all electric
How is acrylic recycled?
The collected acrylic goes to a company that will remove the PE protective foil of the material. This foil is recycled separately and can be used for roadside poles and sheet piling for example. Then, the residue of the acrylic sheets, tubes et cetera will be shredded into small blocks and is going to be driven in big bags to the acrylic factory.
In a closed vessel, the acrylic, without the addition of oxygen, is heated such that the polymeric plastic disintegrates into the separate “links” where that polymeric resin was composed. These links, the basic building stone, is called monomer. In this case, we make from polymethyl methacrylic (pmma) a monomethyl acrylic (mma). This is a quite simple and clean process. Monomer is vapour at high temperatures. This vapour is collected and by cooling in a downward side branch from the top of the vessel, the vapour becomes a liquid again. The liquid is then completely purified with a filter, so that the colours are removed, leaving a completely clear liquid. The filter residue of this purification is used to heat the recycling installation. The minimal residues, which are left over after combustion – together with the dust particles from the smoke filters- are eliminated. These fractions are very small and not particularly toxic. It is mainly carbon.
The filtered clean monomer is then used to make new, beautifully bright or coloured acrylic sheets, but now from 100% recycled material. This sheet is called Versato® Greencast.
Can I purchase Greencast® 100% recycled acrylic?
Yes, you can purchase Greencast® online via our web shop. You can also purchase this material via the telephone via our plastic specialists.
We have Greencast® 100% recycled acrylic on stock in:
Clear: 3, 4, 5, 6, 8, 10, 12, 15 and 20 mm
Is Greencast® 100% recycled acrylic identical to ‘virgin’ clear acrylic?
The characteristics of Greencast® acrylic is 99% identical to ‘virgin’ clear acrylic: a very stable plastic with unprecedented clarity that does not yellow and can be used for many useful, technical or beautiful applications.
The VICAT softening temperature is slightly lower and the clarity of the material is slightly less. This is only noticeable when the light passes through the sheet over minimal 50mm.
Greencast® is just as cast acrylic:
– extremely colour fast
– very stable
– Hardly aging mechanical, optical and thermal properties
Is it also possible to recycle Greencast® 100% recycled material?
Yes, this is possible! If you have acrylic that you do not use anymore, please contact us. (firstname.lastname@example.org)
Does acrylic have a cradle-to-cradle certification?
We have done research with the EPEA, the certificating authority of the cradle-to-cradle organization. That is absolutely feasible and a certificate is possible. The lowest grey level is undoubtedly achievable.
However, for a certification range, PyraSied is a distributor dependent on its producers. Given the time and money to invest, this is not a simple decision for a medium-sized manufacturer, even if we offer financial support in this regard.
