GW Environmental & Consulting Ltd

Environmental consultancy

At GW Environmental Consulting we aim to tackle hydrocarbon contamination using naturally occurring sustainable solutions.

Underpinned by over 20 years of experience in managing assets and maintenance within large oil companies GW Environmental Consulting has developed a range of multi-use products that will clean and bioremediate all forms of hydrocarbons from fast food fat to biodiesel and ethanol.

Our environmental consultancy provides cost-effective, industry-proven solutions to reduce or eradicate the risk of hydrocarbon contamination wherever it may occur both for now and for the future.

We work with all businesses no matter what size, to help provide best-practice advice, product delivery, training and support to mitigate contamination at the source without posing a threat to the environment.



  Petroleum Facilities


A single multi use cleaning product has been developed for use on the forecourt, fuel storage areas, refineries and vehicle workshops.

As it actively ingests hydrocarbons any post  cleaning waste water can be allowed to run into the fuel separator system where it will continue to remediate and clean the contents of the fuel separator of ethanol and harmful BTEX compounds. 


Ground  Contamination

Our proven in situ technology can remediate hydrocarbon contaminated soil within 90-120 days , 60% cheaper than traditional methods.

Treating contamination in situ is the most cost effective and environmentally sustainable solution to spill events and historical ground contamination.


Marine Applications

Our Marine Products can be used for the cleaning and degreasing of decks, bulkheads engine rooms and port facilities helping to reduce the risk of injury through slipping.  

Most importantly you can minimize  the risk of  hydrocarbon pollutants entering the ocean.

             Environmental contamination is one of the greatest challenges we face in the world today. In 2015 all Member States of the United Nations adopted a set of 17 goals which are a blueprint for transforming our world by 2030. Goal 15 is Life on land: sustainably manage forests, combat desertification, halt and reverse land degradation, halt biodiversity loss.


As populations increase, sustainability in life as we know it presents a challenge: energy, water, food are compromised with the threat of pollution and damage to ecosystems.


Bioremediation has the potential to restore contaminated environments inexpensively yet effectively. It is the most environmentally conscious way to solve the problem of pollution by utilizing the organisms growing naturally in the same environment to remove contaminants. This solution is harmless to humans, animals and the environment as a whole.


According to the American Environmental Protection Agency, bioremediation is a “treatment that uses naturally occurring organisms to break down hazardous substances into less toxic or non-toxic substances”. Microorganisms have the ability to destroy a variety of organic contaminants under either aerobic or anaerobic conditions and can immobilize toxic metals. 


The goal of using bioremediation methods is the biological mineralization of organic compounds to CO2 and water.  Bioremediation technologies compare very favourably with traditional remediation technologies. They require fewer resources and less energy than conventional technology, and don’t accumulate hazardous by-products as waste. Tapping into the microbial resources will certainly contribute to delivering the sustainable, biobased circular economy.

Can you afford to slip up?

Can you afford to slip up?

 Can You Afford to Slip Up?


Slips, trips and falls still represent the largest number of incidents in the UK every year. When a slip, trip or fall occurs the chances of it resulting in a broken bone are approximately 95%


In February 2014, there was a milestone change in the way companies are fined in relation to breaches of health and safety which applies to any case that is brought to court.  Now fines can be administered in relation to the seriousness of the incident and the size, profit, turnover of the organisation in which the incident took place.


When reviewing a case, the court will take into account how processes, installations and systems comply with minimum industry standards and what lessons learned actions and investigations were put into place with regards to any similar or previous incidents.


This new regulation has now levelled the playing field between the large and small employer. Historically, incidents of slips, trips and falls that were brought to court for examination and eventually sentencing seldom exceeded £5000.  The fines did not take into account the size of an organisation so whereas for a small company a £5000 fine could have a considerable effect for the larger organisations could be easily absorbed.  


The change to the sentencing means that fines for the same incident can be far greater than before for larger organisations. The scale demonstrates that a company with a turnover of over £50m per annum could be fined up to £10m.


To reinforce the fact that this is not just a threat in a recent case with Thames Water the court of appeal has stated the fine could equal up to 100% of the company’s pre-tax profit which is more than £100m.


Changes in the workplace


Is occupational and health and safety training enough?  Companies can show good due diligence if they are able to prove they have a program of regular and relevant safety training, however the demographic of the workplace is changing. 


Industry figures show the cleaning sector is one of the biggest employers of migrant labour. Furthermore, the risks of the migrant labour having an unforeseen accident have also increased. The reasons for this tend to be socioeconomic. Many migrant workers have grown up in an environment where a safety culture as we know it in the UK,is not prevalent.


So with the risk and the penalties increasing safety innovation should always be at the forefront of any cleaning business or enterprise.


So Where Does the Real Risk Lie?


It is not just the wet floor where the hazard is. Many environments by their very nature are made more slippery through the day to day activities that surround them.

To further complicate the issue substances that promote slips, trips and falls can be walked from one area into another where people may be unaware of the impending added hazard.

Typical examples of this can be found across petrol filling stations, oil storage depot site offices or the ingress and egress areas of kitchens and canteens.


What Can Be Done to Help Minimise the Risk?


If you are working in an environment where fats, oils, grease or petrol, diesel and other lubricants are often spilt or accumulate in an almost invisible film on the surface of the floor what can you do?  

The answer could be in what you use as a cleaning agent and how it works.


We all know water cannot clean effectively so we add a chemical detergent. The surfactants it contains are made of molecules that have two different ends. One end is strongly attracted to water and the other to dirt and grease. However, like any chemical reaction there is a limit to how much dirt and grease that can be picked up at any time – and often it is not all of it.

I you look at the ingredients on a typical detergent bottle you'll see lots of other chemicals , many of which are harmful to both the user and the environment.

Biological detergents contain active chemicals called enzymes, which help to break up and remove food and other deposits. The main enzymes are proteases (which break up proteins), lipases (which break up fats), and amylases (which attack starch). However ,enzymes have a limited capacity and time span in which they can operate.


 Bioremedial cleaning agents on the other hand, bring a new dimension to cleaning surfaces especially where the main source of contamination is derived from hydrocarbon, which covers the range incorporating cooking oil and grease all the way through to oil and petrol. And yes, everything in the hydrocarbon range is slippery and does not mix with water.


How Do Bioremedial Cleaning Products Work?


Bioremediation is a naturally occurring process that is happening all around us every day.  At its core are harmless bacteria who actively ingest and break down fats, oil, grease, petrol and lubricants leaving behind only water and inert gas. 

Bioremediation was traditionally used for attacking major oil spills and leaks but now it can be incorporated into daily cleaning products.


What Are the Advantages of Bioremedial Cleaning Products?


The advantages of bioremedial cleaning products are numerous and have benefits for not only the user but also the environment as a whole.


In terms of cleaning hydrocarbons off floors and surfaces bioremedial cleaning products are not limited by chemical properties or a fixed enzyme content. The bacteria will ingest and remove all the hydrocarbon and will multiply to eat more hydrocarbon until it is all gone – and the floor is returned to its normal non-slip design status and of course clean.


Once the dirt and hydrocarbon food source has been removed from the cleaned surface the bacteria then perish as their food source has been removed. The bacteria will however continue to bioremediate the dirty cleaning water and beyond!


Once the waste cleaning water has been poured into the designated mop sink or disposal point the bacteria will continue to bioremediate any fats, oils and grease in the drainage system, preventing blockages and reducing bad odours. In fact, regular cleaning with bioremedial agents will build up a harmless biomass in the drainage system which will ingest any fats and oils that incidentally enter the drains through other activities such as dishwashing.


Be proactive!


We, employers all have a duty of care to our employees and we all have a social responsibility to protect our environment as well. Act now to prevent accidents in your facilities by making a simple change in the cleaning products that you use. If you no longer want to expose your staff and customers to harmful chemicals choose bioremedial cleaning products. And the environment will be grateful too.


A GW Environmental Consulting we have developed a range of products that can be applied directly or integrated into everyday cleaning activities to help reduce the risk of slips and trips in some of the more difficult working environments where hydrocarbons are widely used and spilled.

 Regular cleaning with products containing the right micro-organisms to degrade the fats, oil and grease is the perfectly natural way to treat wastewater and help keep domestic pipes and drains flowing.
