Styrene removal in the composite industry

Composites are an extremely durable construction material, because of their near infinite lifespan and the extreme strong and lightweight properties. The composite industry is now feeling an increasing desire to make their styrene removal a top priority. To modernize their companies and reduce their environmental footprint. Solving the styrene emissions in a durable and green way, at low cost, with very little maintenance and a small footprint is hereby essential. Meet the VOCUS.

The VOCUS is a modern and biological solution that increases the green image of your products, because of the responsible way the industry produces her products. There is no additional (fossil) fuel necessary, no additional chemicals and no big amounts of regular waste.

Water, nutrients and care will do

The VOCUS is a modern full biological system. It will function independently within the optimum parameters that are maintained automatically by the system. It will adapt itself to the inlet styrene load and is capable of the fluctuations that are known in any normal industrial production rhythm.

The VOCUS is a biological system. This means that the actual styrene removal is done by biology in the VOCUS reactor that consumes the styrene. This is the reason that the operational costs are extremely low compared to any other technology.

High quality styrene removal that will last for decades

Just some water, nutrients and care will let the VOCUS to do its job efficiently. Long life of the system, all build from the most durable plastics (composite housing) that will last for decades, while the biology will be maintained throughout all this time feeding itself on the incoming styrene.

Why choose the VOCUS:

  • Complies with the EU’s strictest VOC emission legislation. Any removal performance can be achieved due to modular and flexible design. Outlet concentrations can be achieved as low as <10 mg C/Nm3. But the VOCUS can also be designed such that they only do 30% removal. Extremely flexible and tailor made possibilities.
  • Linear expandable system, at any time additional reactors can be added easily to adept to increasing production or a demand for higher performance due to legislation in the (near) future.
  • The VOCUS reactor housing is made of composite, customers may want to make their own VOCUS housing to save costs and increase the company’s involvement and show-off in the greenifying project.
  • No piloting necessary, the VOCUS is proven and scalable in the whole of the composite industry.
  • Extreme low footprint, due to reactors that are built into height. Leaving more space for production & storage.

(English) Legislation on solvent emissions in flexographic industry.

Industrial emissions have been under the microscope for the last few years. There’s a green switch happening and companies EU wide need to think about their environmental policies. Many companies, also in the flexographic industry, struggle between keeping government and consumer happy with their emissions on one hand and making profit with their companies on the other hand.

Directive 2010/75/EU

The Directive 2010/75/EU of November 24, 2010 on industrial emissions is in force right now for -among others- the flexographic industry. This directive is mandatory to be implemented in every member state of the EU. The EU wants to unify the legislation in all countries to ensure that competitiveness of the sectors remains a level playing field in the EU. The EU law isn’t an easy read but since it’s our job at Pure Infinity we make it a little easier for your business with this blog so you can easily understand ánd implement the legislation.

Legislation on solvent emissions

If a factory in the EU emits more than 15 ton of solvents per year the company needs to meet the emission restrictions in the directive. For the flexographic industry it is set that between 15 and 25 ton the fugitive emissions are allowed to be 25% of the total solvent input. Above 25 ton the fugitive emission is allowed to be 20%. Companies either have to comply to the emission limits (which is 100 mgC/Nm3 in the air emission of the factory) or comply to the rules of the reduction scheme as laid out in the directive. It is important to investigate which regime is best for your company.

Consequences

Punishments for not obeying  are also similar in every country. Closing down a production location isn’t an exception and also high fines are common consequences. Luckily your  company doesn’t have to let it get that far. There are green, affordable and lasting solutions that comply fully to the law.

Green solutions by Pure Infinity

There are a lot of options out there (link interne blog). Pure Infinity can provide two options for your company in the flexographic industry:

  1. VOCUS: lower solvent emissions 25/100 ton a year due to a biological process with very low running costs and green and proven technology.
  2. BONCUS: solvent recovery by converting into green energy (therefore great ROI), making money by not destroying valuable raw materials.
