Glass Filtration Media

We are a manufacturing company based in the North East of England. We operate under strict ISO control systems and have in place full accreditation for ISO 9001 (Quality), ISO 14001 (Environmental) and ISO 18001 (Health & Safety).

Our product is also accredited to BSI PAS 102 which is a European recognised quality standard as well as being accredited by the Drinking Water Inspectorate to Reg31. Reg31 is a quality standard that states our media is of such high quality it can be used to filter water for human consumption.

The sizes we produce are listed below

  • 0.0 – 0.2mm – Super Fine (Wet Blasting Media)
  • 0.2 – 0.5mm -  Fine (Shot Blast Media)
  • 0.5 – 1.0mm - Medium (Shot Blast Media & Water Filtration)
  • 0.7 – 1.5mm - Heavy Medium (Shot Blast Media)
  • 1.0 – 2.0mm -  Ultra Coarse (Shot Blast Media – Heavy Metals & Water Filtration)
  • 1.0 – 3.0mm (Water Filtration)
  • 3.0 – 6.0mm (Water Filtration)

Our in-feed stock is sub 12mm container glass from household recycling schemes throughout the UK and is 100% recycled glass cullet which would otherwise be committed to landfill. This offers environmental savings and green credentials for any company using it.

There are also significant health benefits to be had because our recycled glass media does not contain any crystalline free silica or heavy metals. This makes it a clean and safe material for the user. It is inert and completely non-sharp product which can be used in environmentally sensitive areas. We produce recycled glass media for the shot blast, water filtration, cementation and decorative aggregate industry’s amongst other things.

Each media has its own bespoke manufacturing technique, which enables us to offer guaranteed and consistent quality across our product range.

We can dispatch our media from single pallets to full load consignments to anywhere within the World – this means we can deliver to site or to your business premises.

If you would like FOC samples of any or all media sizes listed above along with the associated Material Safety Data Sheet (MSD’s) then please don’t hesitate to contact our Sales Team on 01642 458666 or

Benefits of using WRL Glass Grit for Shot Blasting

Recycled glass grit can provide companies of all sizes with a cost effective, environmental solution compared to traditional abrasive media.

WRL glass grit is manufactured to, and in accordance with, BSI PAS102 and under ISO 9001 quality control systems. These accreditations mean we can guarantee constant quality time and time again.


Glass grit performs as well, if not better in some cases than conventional shot blast abrasives Glass grit particles are angular to sub-angular and have the ability to cut coatings exceptionally well when used in abrasive blasting Glass grit can produce a "white metal" finish which can be superior to other abrasives.

Glass grit can be used in volatile areas such as glass pipe lines, as there is no ‘cold sparking’ Low "rust-back" finishes can be produced by using glass grit. Unlike other abrasives, glass does not contain significant chlorides or other salts which can accelerate the corrosion of cleaned surfaces.

Using glass grit can have the potential for lower dust generation than other abrasives during use. Not only does this have many H&S benefits, it can also reduce the number of complaints received
Glass grit is also free from silicates and heavy metals meaning it is a safe product for the user.

With less dust generation, glass grit can leave less abrasive residues on cleaned surfaces thereby reducing post-blast cleanup costs and time. Unlike many conventional blast abrasives like copper slag, recycled glass is classed as an inert and non-hazardous waste, this can significantly reduce the disposal costs.


Recycled glass grit is non-toxic and inert, unlike copper and other metal derived abrasives that contain heavy metal residues. Heavy metals can be harmful to the environment (& the user), particularly plant and marine life. Glass grit can be used when working in and around environmentally sensitive areas such as watercourses, marina’s etc as the media is completely inert and will pose no
environmental risks should spillage occur.

Disposal of “spent” glass grit will have fewer negative environmental impacts than slag-based abrasives as glass is not classed as hazardous waste - Unlike slag-based abrasives, glass contains no heavy metals which can potentially increase potential environmental contamination. Glass grit abrasives can also be reused more than some other lower cost abrasives before becoming "spent", therefore having environmental benefits as well as financial ones.

Using recycled glass grit abrasives utilises glass cullet sourced from local container glass waste streams and creates a resource from a material that would otherwise be committed to landfill. This can significantly reduce a company’s carbon foot print and demonstrates a proactive attitude to reducing waste and protecting the environment.

Currently there is a surplus of mixed glass cullet due to an imbalance between production and collection. Using recycled glass for shot blasting provides the opportunity to correct this imbalance and saves it going to landfill.

Health & Safety

Unlike many other mineral based abrasives, glass grit has no detectable "free" or "crystalline" silica, greatly reducing the potential health hazards for u ser which eliminates users from silicosis, a lung damaging disease which can be fatal.  Glass grit has the potential for lower dust generation than some other abrasives during use, this can be safer to use in public areas. It can also help decrease the
amount of complaints received.

Unlike slag-based abrasives, glass grit contains essentially no heavy metals which can potentially increase occupational exposure during use. Recycled glass grit is a clean and safe to handle material. All of our glass grit is completely non-sharp and can be handled without the risk of cutting to the user. However as with all shot blasting abrasives PPE should always be worn

Glass Filter Media

Glass Recycling Process

This process produces a material that is free from sharps and can be handled without the need for gloves.

The product is then elevated to the primary screen which filters out any oversize and transfers the remaining product onto the secondary screens ready for final grading. A fully automated dust extraction system is in operation at all times which ensures the product delivered into the bulk bays is of the finest quality.

Our fully automated bagging line produces 20 or 25 kg packs which are stacked onto four way pallets. At this point a final quality inspection takes place before transfer to the dispatch and holding area.

Filtration Media

We have the capability to handle 1 tonne sacks or deliver via bulk tippers and tankers upon request.

Throughout the whole process our emphasis is always on producing a quality product that achieves the highest standards required by our customers and end users.

Crushed glass can be used as granular media for filtration applications such as in the treatment of potable water, municipal waste water, and industrial waste water.

There is also potential for the use of glass as granular media for filtration of swimming pool water and various aquaculture and fish farming applications where water is recycled or high purity is demanded.

Clause 7 of PAS 102 relates to non-potable water applications including tertiary sewage treatment, industrial process water treatment, landfill leachate and swimming pool filtration. It excludes potable water filtration, specifications for which are still under development.

PAS 102 specifies colour, contamination limits and particle shape, and particle size requirement are given for three grades of processed glass.
