Arqlite turns plastic waste into value

by manufacturing construction materials from all forms of plastic waste; its main product is an artificial stone aggregate than can be used as a replacement for quarry rock in concrete and base course for slabs and roadways.

The use of non-recyclable plastic is unique, there are few other uses for waste plastic beyond being disposed in landfills or burned in incinerators.

Arqlite provides an innovative recycling service to large manufacturers and cities at a similar price that they are paying for non-sustainable disposal.

The final product is a new type of artificial rock that when replacing quarry rock creates a concrete that is eco-friendly, lighter, quieter and has better insulating properties.

Arqlite Construction Benefits Vs. Rock

60% lighter

PlumaBesides contributing to an easy handling and less transport costs, lighter concrete within a building reduces the size of the structural support required to carry the dead weight leading to significant reductions in costs and materials.


10 times better insulator

InsulatorArqlite stone greater thermal and acoustic resistance compared to mineral aggregate result in energy conservation and more comfortable spaces by reducing heating and cooling needs that represent 60% of the total energy consumption in buildings.

Controlled size, shape and proportion

NuggetsBecause of its controlled uniform shape and sizes, the use Arqlite nuggets makes it possible to define coefficients as optimal amounts and drainage capacity, making the product a great candidate for  slabs, pre-cast and pavement base and sub-base.

Cost Optimization

Cost OptimizationArqlite nuggets have a competitive price compared to quarry rock and its use in the concrete mix provides lighter structures, reducing the requirements for structural base and thus the use of steel beams and concrete. 


LEED Scoring

LEED-plaqueTo receive LEED certification, building projects satisfy prerequisites and earn points to achieve different levels of certification. The use of Arqlite scores points on categories 4 and 5 for being recycled and locally produced.

No water waste

13159442411948661264Water Resistant.svg.hiIn order to calculate the quantity of water that aggregate will either add or subtract to the paste, absorption capacity, effective absorption, and surface moisture must be calculated. Arqlite does not absorb water, simplifying processes and saving resources.

Minimum reaction to temperature variations

GraphBeing Plastics less thermal-conductive than rock, reduce its reaction to extreme temperature variations and thus the possibility of fracturing or altering the concrete mix by thaw.

High resistance to chemicals

chemical_registanceIts high molecular strength while being synthesised from compounds of low molecular weight generate a low weight material of high wear resistance to acids, alkaline and solvents, lasting for centuries.

Arqlite Environmental Benefits

Incorporating Arqlite to the mixture proportionally reduces the impact of arid extraction and the pollution from cement manufacturing. Diverting these plastics from landfills  prevents the contamination of waterways, land and air, thus contributing to the health of the worldwide population and the entire ecosystem.

CO2 Reduction

Arqlite has 10 times better thermal insulation than quarry rock, meaning a lower carbon footprint and lower utility bills by reducing the amount of energy required to heat or cool the building (more than 60% of the electricity used in buildings is for air conditioning). Download CO2 Calculator Arqlite vs. Rock


Landscape Conservation

Because it is locally produced, Arqlite reduces CO2 generation by minimising transport in comparison to quarry mining away from the cities. Reducing mining will also help reduce the environmental impact of rock extraction.


Landfill Divert

In 2014, 300 million tons of plastic waste was generated around the world. This figure is projected to reach 600 million tons by 2050. Arqlite manufactures construction materials from plastic waste, both the recyclable and non-recyclable plastics, helping divert 280 cubic yards of plastics from landfill for every ton of Arqlite produced. 


Plastics and the Environment

1302584_Bales_of_plastic_for_recycling-300x224The annual consumption of this material has increased from about 5million tons in 1950 to almost 400 million tons in 2014. And it is expected to be doubled by 2050.

Of all waste generated, over 80% is dumped or taken to landfills, 8% is incinerated and only 7% is recycled. This is mainly because more than 70% of daily use plastic products are made from combined or complex plastics that canĀ“t be re-inserted in the production stream and are considered as un-recyclable.

The considerable growth in consumption of plastic is due to its versatility to be customised GRN_plasticbag_Australia_TroyMayne_web-300x201to each specific requirement and its low cost. It is a very light and very durable material and it does not degrade easily as it is resistant to many chemicals, water and aggressions. Important features that Arqlite takes as an advantage is its very good thermal and electrical insulation.

Most plastic is sent to burial, taking between 100 and 5,000 years to degrade, polluting land and groundwater. Another part is incinerated causing pollution and toxic emissions that stay in the atmosphere, in addition to the higconcrete-e1404143581883hly polluting ashes that need to be treated and isolated.

A Perfect Society: Arqlite + Construction

World production of concrete was estimated at more than 3,000 million tons in 2012. While concrete is a material widely used for its ease of application and nobility, with the passing of the years there are two variables that can still be optimised: Its environmental impact and high weight.

The natural aggregates used for composition are extracted from non-renewable environmental resources, degrading the landscape, causing erosion problems and affecting the flora and fauna of extraction points. We can see this "shortage" of resources as an opportunity to start using other disruptive materials as artificial aggregates.

Arqlite is the perfect society for the construction industry, helping divert hundreds of thousands tons of plastics from landfills into a lighter and more efficient concrete.
