SUSTAINABILITY

BEGINS AT HOME

Our dedication to sustainability is not just a business imperative; it is a moral responsibility to ensure that our actions contribute positively to society and the planet. We place sustainability firmly at the core of our strategic vision and ensure that it is a driver in all of our business decisions. 

We believe a truly sustainable future is characterised by continuous improvement, collaboration, and innovation, but we also recognise that the journey may not always be linear. With the aim to be progressively transparent about the impact of our business, we are committed to publishing an annual sustainability report to provide a comprehensive overview of business-wide sustainability management at SLS.

SUSTAINABILITY ATTRIBUTES


See our full range of products with sustainability attributes.

We recognise that determining the sustainability of products you bring into the lab is a difficult and often complex process; there are currently many different approaches on how more sustainable products are marketed.


Faced with such complexity, it is often easy to embrace ‘green’ or ‘sustainable’ icons or narratives. But you can often be faced with the question of how or why they deserve this ‘eco’ status.

At SLS, our aim is to provide comprehensive information about the products we sell and enable you to make the most well-informed choices as possible. Therefore, our sustainability attributes align to the following principles:

-          specific to individual products

-          evidence-based using primary data from our suppliers, and

-          aim to include as much information as possible about the entire product lifecycle

This approach will enable you to make more conscientious choices which align with your lab or organisation’s sustainability strategy.

Our attributes are defined by the five stages of a product lifecycle: from raw material, to manufacture, packaging and distribution, use in the lab, and disposal (or end-of-life). 

 

 

A product receives an award/icon if it meets one or more of the criteria under that lifecycle stage. By viewing a product online or in any forthcoming marketing material, you can use these icons to straight away determine how that product performs from a sustainability perspective throughout the stages of its lifecycle.

To understand why a particular product has received an award, you can click on the sustainability tab of that product and there will be a list of criteria specific to that product from the list below:

Raw material:

-          Made using more than 80% recycled or renewable material

-          Made using material with a reduced environmental impact, e.g. a refrigerant with a low GWP (Global Warming Potential)

-          Designed to reduce the use of raw materials

 

Manufacture:

-          Made in a facility which runs on >90% renewable energy

-          Measures were in place during the manufacture of this product to reduce energy consumption

-          Measures were in place during the manufacture of this product to generate less waste

-          Measures were in please during the manufacture of this product to reduce water usage

-          Aligns with the principles of green chemistry

 

Packaging/distribution:

-          Manufactured in the UK or Ireland

-          Country of origin has an Environmental Performance Index (EPI) greater than 60

-          Plastic-free packaging

-          Reduces the need for packaging

-          Packaging return scheme offered for this product

 

Use:

-          Product contributes to a reduced energy consumption

-          Product contributes to a reduced water consumption

-          Product reduces or replaces the need for consumables

-          Built to last – minimum 5-year warranty, and spare part-servicing available

 

Disposal:

-          Product is recyclable (excludes packaging). A recycling or repurposing scheme is offered for this product.

-          A feature of this product enhances its biodegradability.

 

It is important to note that these attributes do not provide quantitative carbon metrics for the product lifecycle.

TIPS FOR A

SUSTAINABLE LAB

Centrifuge tubes

Glass centrifuge tubes

Pipette tips

Volumetric (bulb) pipettes or graduated if Class A
accuracy is not required. <1mL - use microsyringe with
repeating despenser attachment

Weighing boats

Weighing papers or glass boats, FSC certified paper or weighing boats

Tubes & bottles

Substitute glass wherever possible

Single-Use Plastics

  • Where possible substitute plastics with glass, card or paper
  • Whilst it is good to recycle it’s even better to re-use or reduce. Where sterility isn’t critical
  • e.g. teaching labs, reusing will not only cut plastic waste but reduce costs
    • If possible, reduce the size of tube or container that you use
    • Try to cut down on packaging – buy in bulk and share resources with others

 

Saving Energy

  • ULT Freezers – by increasing the temperature from -80 to -70 the energy consumption is potentially reduced by up to 37%. Not only that, it puts less strain on the compressor and lengthens the life of the freezer!
    • Use racking – prevents big temperature changes
    • Keep an inventory so old samples aren’t taking up valuable space – cutting down the need for more freezer space
    • Keep opening times down to a minimum
    • Defrost regularly
  • Fume Hoods – generally ventilation systems and fume hoods can fall into two categories – Constant Air Volume (CAV) and Variable Air Volume (VAV). The amount air flowing through VAV fume hoods can be adjusted by the height of the sash. If the sash is lowered the speed of the exhaust fan and the volume of air being exhausted is reduced. The energy savings could be as much as 40%
  • Drying Cabinets – use a timer switch so these aren't left on overnight or over the weekend
  • Laminar Flow and Biosafety Cabinets – turn off when not in use. They can consume around 15kWh/day – about half as much as an average house!
  • Energy – anything that’s used for heating or cooling can consume a lot of energy so switch it off when not inuse. Alternatively use timer switches so equipment can be turned on and ready for use first thing – if needs be. Remember the heat generated from freezers, water baths, Dri Blocks, ovens etc will also make your lab’s air con work harder and in turn increase energy usage
  • Don't Bin It, Fix It! – get items fixed or serviced. We have our own service centre – for more information please email: [email protected]

THE LIFECYCLE CARBON STORY OF THE ECOCOOL

Driven by a shared determination (and a healthy dose of curiosity), Grant and SLS set out to calculate carbon data for the product across its lifecycle stages. The goal was not just to crunch the numbers, but to make the results easily digestible and actionable. Therefore, an imperative outcome of the project was to convey any carbon estimates in relative terms, by comparing emissions to something universal or commonplace. This would make it easier to grasp the significance of what, to most, would otherwise be a rather abstract metric. The product chosen for this more in-depth analysis was Grant’s ‘ecocool’ refrigerated circulating bath.

Eppendorf F740HI Racking Study

Introduction

Ultra-Low Temperature (ULT) freezers are well known to be high consumers of energy. Holding set temperatures 90°C to 100°C colder than their environment will always require a significant amount of energy.

One way to reduce ULT freezer energy consumption is to warm up the set temperature. By doing so energy consumption will be reduced from 18-34% depending on the model, age & condition of the freezer.

When considering warming up their ULT freezers, some end users raise concerns that by taking such an action they may expose their samples/contents to unfavorable temperatures during their day to day operation.

SERVICE & REPAIRS

Be more sustainable by servicing your laboratory equipment instead of replacing it. Servicing helps to prolong the life of lab equipment and avoid repeat purchases, saving you money but alsoreducing unnecessary waste.

 

SLS understand that when it comes to servicing equipment, speed and convenience are just as important as the quality of the workmanship. That is why the SLS Service Centre tailors itsservice to meet each customer’s specific requirements. Our experienced, fully qualified, industry authorised engineers and service partners can service and repair a broad range of laboratory instrumentation nationwide.
