Harena is simply the most effective and environment-friendly solution for fuel and oil spillage on the market!

What is Harena?

  • Harena is an oleophilic coated mineral that rapidly adsorbs hydrocarbon that occurs naturally in fuels and oils, isolating them from the immediate environment.
  • Harena will absorb all hydrocarbon including synthetics, and fuels such as petrol and diesel, including the vapours.
  • Harena is fully hydrophobic and will actively and consistently repel water. This enables effective use in all weather conditions and environments.
  • All fuels and oils become non-flammable when fully bonded to Harena, facilitating the complete removal of the spilt material from site whilst minimising the risk of secondary accidents.
  • Used Harena is environment-friendly! Once fully bonded, Harena will form a dry oil-free crumb and due to its non-leaching properties, it can be removed quickly, cleanly and efficiently.
  • Harena has been Waste Acceptance Criteria tested (WAC) BS EN 12457
  • Harena is easy to store, including outside (weatherproof bags), and can be quickly applied as a dry, free-flowing product. Harena is non-flammable, safe to handle and non-toxic, with an indefinite shelf life.

Contamination Prevention

I think I can say that I have been impressed by the characteristics of Harena and see the opportunity for it to be used innovatively in pollution prevention settings, where particularly its ability to address hydrocarbon contamination, including vapour risks, is a welcome addition to the incident management toolbox. In relation to surface clean-up, prevention of oil based materials getting into drainage systems and managing spillage events in re-fuelling areas the product offers an interesting addition to aid safe design.

Fuel and Oil Spillage

The broad range of features of Harena enables it to be a perfect tool for dealing with ground and waterborne spillage. Harena will absorb from a variety of ground surfaces including semi-porous surfaces such as concrete or asphalt. Providing a complete clean without residue or staining (see photos below).

When used to clean up volatile hydrocarbons, Harena is able to add some significant safety factors. Both the liquid and vapour part of the hydrocarbon molecule is bonded creating a much-reduced spark and fire risk than with conventional options.

The next photo highlights the difference between Harena (left) and sand when used to clean up a petrol spill.

This is significantly safer and cleaner for both the environment and the user at source, as well as removal and disposal.

The spillage remains bonded and forms a non-leaching dry crumb that is simple to dispose of. Used Harena remains fully hydrophobic after use.

Forecourts

Harena can increase fire safety and reduce risk when utilised as a spill clean-up method for small everyday customer spills and filling overflows as well as any larger scale spillage. Harena is an ideal replacement for sand in forecourt fire buckets.

Transport

Harena has multiple uses within the transport sector. Here are a few examples:

Highways construction and maintenance

Harena can be utilised for the construction and maintenance of highways. Harena will successfully bond with even highly viscous hydrocarbons such as bitumen. Ideal for creating clean working environments. The broad range of machinery used means fuel or hydraulic spillage is inevitable. Harena will also increase site safety.

Logistics

Harena can be utilised by businesses that operate large vehicle fleets as a precautionary measure for spillage. This could at the fuel filling depot and/or carried as part of a spill kit on fleet vehicles. Harena’s safety features mean it ideal for carrying on fleet vehicles when compared to conventional options.

Accident Safety

Harena can significantly improve site safety at highways accident. The rapid adsorption of fuels and oils will minimise the risk of environmental damage, slip hazards and fire. Thereby reducing the potential for secondary accidents to persons and infrastructure during clean up operations.

Aviation

Harena has the ability to improve safety and reduce the risk of potential accidents at airports hangers, and aircraft maintenance depots. In an industry where the safety is always the top priority, Harena is the best solution to reduce accident risk from slippage, fire or environmental damage.

Waterborne & wet environment spillage

Harena is a target specific method for hydrocarbons, enabling it to be an effective solution in wet environments and waterborne spillages. Harena will only target hydrocarbon spillage, completely isolating it from the surrounding body of water. Hydrocarbons remain completely isolated and will not leach.

Other hydrocarbons

Harena is capable of bonding with any type of hydrocarbon molecule including vegetable oils, emulsion paints, emulsified polymers with the same benefits as more conventional oils.

Land remediation

Harena has a beneficial use for remediation within contaminated soils and sediments. Fuels and oils that are mixed with soils are often difficult and costly to remove effectively.

Harena can be mixed with these sediments and will isolate the contamination effectively. The non-leaching ability of Harena means these contaminates will remain captured and can be left to breakdown utilising natural bacteria within the sediments. Additional live bacteria can be added to quicken the process if required.

Hydrophobic sealing

Harena has uses beyond just hydrocarbon adsorption. Utilising its hydrophobic feature, Harena can be used to create a water resistant seal in a variety of different environments.

The high density of Harena coupled with its hydrophobic capacity and resilience to changing environmental conditions means Harena is able to form an effective seal with good longevity.

Disposal after use

Landfill

Used Harena has waste acceptance criteria tested (WAC) in the UK to be classified as non-reactive hazardous waste in non-hazardous BS EN 12457. Classification may reduce the cost of disposal compared with traditional absorbents.

Composting

Harena’s non-leaching ability enables used product to be composted in an isolated environment where bacteria will naturally break down the hydrocarbons over time without risk to the environment.

Carbonation recycling

Lab testing in partnership with Carbon8 Ltd suggest that used product may be recycled as a construction aggregate. Testing ongoing.

Energy source

Harena can be incinerated and used as an energy source.

Recycled

Used Harena can potentially be incorporated within the production of asphalt.
