Oil Waste Solutions - Achieving Net Zero Goals

Up to a year ago the carbon footprint of oil waste treatment was not a topic that had come up very often. At SAS we know this issue is going to become increasingly prominent. 

What is the carbon footprint of oil waste treatment and transport? Within the space of perhaps a year this changed from a minor question to an central issue that requires to be addressed consistently in many of the projects we are engaged in.

Over the past few months, the team here at SAS, have tried to shine some light on this topic and provide some tools you can use yourself. Tools that give you the opportunity to assess what the impact of net zero requirements will be on your business. 

There will be no hiding from the realities of the drive to net zero for our economy. This issue will not go away and the demands on the industry will only grow to show leadership and commitment. Governments will increasingly push for evidence of positive measures and evidenced positive impact.

 Your customers will increasingly make the carbon cost part of the assessment criteria in contract tenders. You need to know where your process, your business stands within this framework. You need to understand how you can positively contribute and how you and your business can thrive and lead in this changing landscape.

Not many of us ever gave thought to scope 3 greenhouse gas emissions. Yet here we are. It’s time to start caring. We can help of course, here at SAS. Reach out to use if you want to get our thoughts on where you can move your business and your carbon impact.

The SAS MIST in Suriname

Guyana and Suriname, together with French Guyana, form a small section on the northern part of South America. Since 2008 ExxonMobil and some other oil companies have looked for and found substantial amounts of oil. The arrival of the oil industry in Guyana and Suriname has led to the requirement of new environmental regulations and a whole new environmental infrastructure.

The governments have taken a strong line in ensuring high environmental standards and SAS Environmental Services is working with a number of partners in the region. One of our MIST systems is already on its way to the region in order to support the waste treatment and reduction.

The latest member of the SAS MIST family will taking on both drilling slops and production waste using our SlopTreat and SludgeTreat chemistry. It was essential to provide a low energy solution capable of treating large volumes of waste with a very low energy requirement. This keeps power consumption down and minimises the need to store hazardous waste for long periods of time.

The oil industry has the potential to help these economies to grow and at the same time responsibly manage any waste by minimising the waste creation and through fast and immediate treatment of oil waste.

Model 2 : Disposal of Stabilized Oil Sludge

The Scenario

Let us imagine that we have 50 000 tonnes of liquid oil sludge in a storage somewhere and we must move this sludge about 600 km to the nearest disposal site that is willing to accept it. However, the disposal site will only accept it if it is a solid waste not as a liquid waste. There are several ways to proceed from here, but what is becoming increasingly relevant in today's world now is how much carbon footprint our treatment process incurs.

The Treatment Method

A method that is used to turn liquid sludge into a solid waste so that it is safer for disposal and accepted in more disposal sites is by stabilizing or fixing the waste. This is usually done by adding a stabilizing agent to the waste. The stabilizing agent obviously must be taken to the waste; it must be mixed at the site.  The stabilizing agent is usually a clay or perhaps sawdust, depending on the site location. This process increases the waste volume, but it does turn into a solid. Once solid, with no free liquid visible, the waste will have increased the total volume by a factor of three or four. This quantity then must be transported by truck to the disposal site, 600 km away, where it is safely and securely stored for eternity.

The SAS MIST Process

This is one way of doing it, but obviously, we are increasing the waste volume by a factor of three or four. It seems contra intuitive to create more waste just to treat the waste. Alternatively, what we can do is add a little bit of our SAS chemistry and put it through our SAS MIST process. What happens then is rather than adding stabilizers to the waste to turn it into a solid material, we actually remove the water and the oil, leaving only dry solids. The oil is recovered, and the water will be reused. We are left only with the dry solids that we then transport to the disposal site.

 The Advantage

That is a huge saving, rather than increasing the waste volume by 300% or 400 %. we are actually reducing the volume of the waste by about 90 % here, so the carbon footprint is going to be substantially smaller. In the case of this particular example, you're looking at over 20 000 tonnes of CO2 equivalent emissions for stabilizing the waste and transporting it or you're looking at about 1400 tonnes of CO2 equivalent emissions for the SAS MIST process and only transporting a much smaller fraction of the waste. The impact on the carbon footprint by actually treating at the site of storage or generation is absolutely massive.

Your Benefit

How will this help you? By decreasing treatment costs, reducing long-term exposure, making your processes more efficient and staying ahead of your competition by being part of a progressive and sustainable route to Zero Carbon.

The Role of Carbon Offsetting on the road to Net Zero

Achieving Net Zero can deliver a range of business advantages– from demonstrating environmental credentials and building customer confidence in your brand, to improving staff engagement with your broader sustainability programmes. It can even deliver business growth opportunities – building resilience in supply chains, supporting growth in key markets and helping to launch new products and services. 

Companies are taking the lead by measuring, reducing and where necessary, offsetting their emissions. Some of the world’s biggest Oil & Gas Companies are taking the lead in making commitments to meet Net Zero targets. Is it about offsetting?

It is frequently stated that the road to Net Zero is one strewn with good intentions, or in this particular case, one of offset responsibilities. Many industrial processes cannot be replaced with carbon neutral methodologies. It is the case that once a full implementation of reduce, replace and manage is exhausted that the role of carbon offset becomes important. 

Can offsetting carbon emissions really tackle climate change? 

Offsetting alone is clearly not going to tackle climate change. It is simply a part of a planned strategy of carbon reduction.  But even in the best case scenario this transition will take time and in the meantime everyone will have a carbon footprint, regardless of how hard they try to reduce it.  Until we reach a zero-carbon world we need to do something about this unavoidable, residual carbon footprint. Paying to reduce an equivalent amount of carbon emissions through voluntary carbon offsetting is the most cost effective, fast and efficient way of doing this. 

Isn’t carbon offsetting is just a short term ‘stop gap measure’ for businesses to carry on emitting greenhouse gases, rather than address their carbon footprint? Businesses nearly always reduce first. In reality, nearly all businesses invest in reducing their in-house carbon footprint before considering a payment to offset what remains. Internal reduction activities frequently save money, while investing in carbon offsetting involves a financial outlay. Few businesses make this sort of investment without first getting their own house in order and being fully committed to operating sustainably. 

The alternative is doing nothing. Even if a business has done all it can to reduce its emissions it will still have a carbon footprint. Paying to offset them, is better for our environment than the alternative, which is to do nothing at all. Offsetting delivers real benefits for the environment and local communities. 

SAS MIST Process - how it helps with your waste, step-by-step.

Is carbon offsetting enough?

Offsetting is a first step in the right direction and meant to balance the scales. However, current governmental and social pressures push towards a more pro-active strategy in tackling CO2 emissions and tacking responsibility along the corporate chain. Offsetting an already reduced amount of emissions is better. To remain competitive, oil companies must demonstrate they have taken steps in transforming their operations to become as carbon neutral as possible.

SAS Environmental Services has taken this philosophy to heart. Using a combination of innovative chemistry, state-of-the-art engineering and over 40 years of cumulated experience in the industry, we help oil waste companies to reduce their oil waste through low energy processes.

Working towards Net Zero – a Sustainable Business Ambition

To future proof your organisation in today’s fast-changing world, you need to balance economic and environmental considerations to ensure responsible, ongoing success.  Therefore, oil waste companies must develop a continuous improvement program that encompasses the implementation of an energy strategy. 

Waste Management Plans are not new. They have directed robust management strategies of achieving environmental compliance with the least impact on costs.  As the need for the measurement of carbon footprint and mitigation of discharge of GHG emissions becomes commonplace, any waste management strategy must consider the release of GHG into the environment as a significant consideration.  

Governments are pushing their economies towards a range of net zero carbon goals. It is important and virtually unavoidable that companies in the energy and waste management sector step up and reduce their own carbon footprints AND assess how their products and services impact their clients’ carbon footprint.

But what does Net Zero mean?  Net zero simply means achieving a balance between GHG emissions produced and those removed from the atmosphere.

By building a carbon reduction plan that balances these economic and environmental considerations waste generating companies will be best placed to outperform their competition and drive long-term success. 

So, if you are looking to assess your organisation’s carbon foot print and create a plan to reduce it and explain to your client how you can help reduce their carbon foot print, how do you start? Where to begin? Well, we have put together a useful action plan template to help guide you through this process.

What challenges do businesses face in the transition to zero carbon?

Transition to zero carbon will be an important business priority over the next years. Governments are activity setting a target to reach net zero greenhouse gas emissions by 2050, which is expected to result in increasing legislation, as well as incentives, to ensure businesses play their part. 

Moving to a position of carbon neutrality is a significant undertaking, with many challenges facing businesses of all types. The desire to reduce carbon emissions is strong and continues to grow, as new generations enter the workforce and demand change.

Overcoming cost barriers

With increasing environmental pressures often come associated higher costs. The perceived burden of measuring, classifying and putting a programme of continuous improvement of Green House gas  (GHG) is an additional pressure on a company’s resources.

Change is always approached with apprehension and suspicion. However, with CHANGE comes OPPORTUNITY.

At SAS ENVIRONMENTAL, we pride ourselves by providing innovative technical solutions to the treatment of wastes and recovery of valuable hydrocarbon resources. Our innovative technology is proven to recover typically 80% of oily volume and returning it to a useable form. This not only reduces residual waste volume and associated treatment and disposal costs; but provides the benefit of the value of the oil recovered.

SAS Environmental customers’ face the same challenges of reducing the discharge of oily waste by converting much of it to reusable resource.  In the months to come the requirement to measure and report material that contributes to the Carbon loading will become an increasing requirement and the incentive to Reduce, Reclaim, Recycle and Reuse will never have been more important.

---

We now see that the benefits extend from not only reclaiming valuable resource but the equally valuable reduction in GHG emissions associated with conventional treatment and disposal.

This is no better illustrated by the processing of Oily waste at the INEOS site at Grangemouth.

As legislators embrace the needs for reporting of, and reduction of Carbon rich, oily wastes; increased emphasis will be placed on recovery of these ‘wastes’ and turning them into usable, commercially valuable resource.

The Green Tank Clean Solution

More specialised and effective cleaning products and processes are needed now more than ever due to increasingly stringent health, safety and environmental regulations. Using products and processes like this could reduce the volume of waste produced from tank cleaning and dramatically cut project completion times. So, where can we find them?

A way to achieve a more effective process is by using more environmentally sound biobased chemistry, instead of partly biobased or petroleum-based. Unlike in the past, there is now a range of fully biobased products available primarily from suppliers in North America, Europe and China. However, the definition of what is actually a "fully" biobased product is not entirely certain. This definition is important to get right in order to establish the true environmental credentials of the chemicals industry in this field, effectively countering any accusations of greenwash.

The development and use of biosurfactants and biochemicals is aiding the implementation of fully biobased chemicals that can be used in developing new cleaning products. These surfactants are manufactured by bacteria and are subsequently harvested and purified. There are some biosurfactants on the market however, their high cost inhibits the uptake of this technology on a wider scale. Their performance is also not yet comparable to other components to be used in microemulsion formulations.

Here at SAS-ES we want to improve this, which is why we have an active research programme in the development and commercialisation of new biosurfactants with higher effectiveness. This process is called microemulsification and it has proven particularly effective in hard surface cleaning applications in the oil and gas industry. 

A microemulsion forming surfactant system can absorb oil from a bulk oil phase, forming a microemulsion. The same solution absorbs oil from an oil coated surface or fine solid particulates with the same result without forming stable emulsion waste as a result. In the microemulsion environment, any oil is effectively encapsulated within the surfactant monolayer and is therefore no longer in direct contact with the original surface or solid. Oil contaminated surfaces may therefore be rendered completely oil free as a result of the microemulsification process.

The mode of action of these cleaning systems is threefold:

1. The penetration of the contaminating oil layer through the solvent/microemulsion mechanism

2. The microemulsification of the oil components into the water phase

3. The water-wetting of the underlying solid surfaces through the surfactant action
