Sustainability Flashcards
(14 cards)
How many manufacturers on average are there in the UK?
270,000, the majority SME’s ( small to medium sized enterprises)
Manufacturing is the largest emitting industrial sector. In 2019 what percentage did it cause of the UK’s total greenhouse gas emissions?
16%
What sustainability target does the UK have for 2050?
net zero
What could drive SME manufacturers to become more sustainable?
climate change impacts+ consumer behaviours
How can sustainable manufacturing companies support net zero?
- developing renewable energy technologies
- manufacturing products that capture carbon/ use fewer non-renewable resources
What did a survey carried out before the Covid-19 pandemic by Make UK conclude about sustainability and manufacturing?
- Sustainable manufacturing companies enjoy substantial business advantages, with 40% reporting increased profit margins and 30% increased competitiveness.
- Becoming more sustainable can reduce costs and increase profits.
What can be easy and difficult for manufacturers to address when it comes to making the supply chain more sustainable?
- easy: some standard approaches broadly apply, such as replacing inefficient lighting and switching energy suppliers to those that use renewable energy generation
- hard: manufacturing can be complex, involving plant, materials, and processes that can be difficult to decarbonise. need to evaluate supply chain, use of materials, waste management ect.
What are the two broad types of sustainable activities for manufacturers to consider?
- sustainable opportunity activities
- Decarbonisation activities
What are sustainable opportunity activities?
Sustainable opportunity activities are ways small manufacturers can support the wider UK in its journey to net zero.
This includes identifying needs such as developing technologies and creating products to reduce carbon emissions and move towards a low-carbon economy.
Give me six examples of sustainable opportunity activities:
- Enabling low-carbon energy generation
Components used in renewable and low-carbon energy technologies.
Glass manufacturing innovation can lead to advances in solar panels, while advanced glass fibres support longer, lighter, and more efficient rotor blades on wind turbines.
From electronics to the chemicals used in electric vehicle batteries, manufacturing activities can help support the UK’s move to electric vehicles.
- Resource Efficiency
Using scrap metal in sustainable manufacturing, reducing wastage through increasing the recyclability of textiles, and lowering food production miles are examples where more efficient resource use can support wider UK activities.
A key opportunity is through engineering, where embedding low-carbon design at scale could have a significant impact.
- Built environment:
Building materials and processes can help lower embodied carbon footprints and some materials – such as concrete – are 100% recyclable and naturally absorb atmospheric CO2.
Sustainable manufacturers can explore developing modular construction approaches that use lower embodied carbon footprints such as timber, or increasing the use of grey water and rainwater in building water supplies.
- Greening the supply chain
Reducing emissions in the cultivation and production of agricultural produce and removing chemicals from sprays used in farming can help producers downstream in the supply chain to become greener.
Other areas where sustainable manufacturers can help include digitising the supply chain and logistics to foster transport efficiencies like whole-life carbon assessments as part of procurement activities.
- Transport
Transport opportunities aren’t limited to metal casting, glass, and ceramics manufacture that will support creating a generation of electric vehicles (EV).
The UK will require a substantial energy infrastructure to support fleets of EVs while non-EV transport such as aerospace will need sustainable aviation fuels to replace fossil fuels.
- Improving standards
Sustainable manufacturers can help introduce and promote sustainability standards throughout the supply chain.
From sustainable engineering that designs carbon emissions out of products to encouraging recyclability of materials and products such as clothing, manufacturers can support the path to net zero by extending its standards-based approach.
What did Make UK discover about adopting sustainable manufacturing specifications like flat glass glazing?
They found that adopting sustainable manufacturing specifications, such as updating flat glass glazing to 1.4U by 2030 would result in a 32% reduction in building energy usage.
What are decarbonisation activities?
The path to net zero isn’t limited to sustainable manufacturing output.
There are plenty of changes manufacturers can make to their operations and systems.
small manufacturers will need to tailor their decarbonisation approaches to their sector and specific needs and operations, some broader areas may be worth exploring as initial steps.
Give me six examples of decarbonisation activities:
- Green energy
Reducing your business’ reliance on fossil fuels may be a good way to make it more sustainable. Switching to renewable energy may significantly reduce your carbon footprint.
Contact your energy supplier and ask about switching to a green or renewable business tariff.
The big energy companies offer green tariffs, as do independent suppliers.
You could also generate your own renewable energy by installing the relevant technology depending on the type and size of your business, the amount of space you have, and your budget level.
- Energy efficiency
Developing good energy management practices across a business can lead to savings.
The Carbon Trust says most businesses in the UK could reduce their energy consumption by between 10% and 40% with good energy management.
It has a self-assessment toolLink opens in a new window that you can use to assess your business’ performance.
- Lighting
Most manufacturing SMEs require a lot of lighting but it can often be overlooked as a way to reduce energy costs and consumption. According to The Carbon Trust over 10% of energy consumption is due to lighting for some industry sectors.
A sustainable manufacturing company might consider replacing older lighting systems with more energy-efficient LED lighting.
- Heating and ventilation
Manufacturing premises often require high ceilings and good ventilation but this can lead to heat loss and energy inefficiencies.
Many manufacturers rely on ‘blown air’ heaters to heat large spaces with high ceilings.
If this is the case, the Carbon Trust recommends that sustainable manufacturing companues switch to radiant heaters that directly heat desks, surfaces, and other areas that need to be kept warm. The Carbon Trust also says badly maintained boilers can use 10% more energythan those that are well maintained.
It is recommended that you carry out weekly boiler checks to identify any problems and boilers should be fully serviced as often as recommended by the manufacturer.
- Insulation
Reducing heat will reduce business costs so sustainable manufacturing companies should make sure that pipes, valves, and other distribution networks are fully insulated. Other areas that should be well insulated are loft and cavity walls.
The Carbon Trust says this is “the single most cost-effective measure that can be made to the building fabric” with insulation of cavity walls reducing heat loss by up to 50%. In addition, the organisation recommends considering installing polycarbonate secondary glazing under skylights which can also cut heat loss by 50%.
- Waste management and recycling
UK manufacturers produce a significant amount of waste material with Government figures estimating that 43.9 million tonnesLink opens in a new window of commercial and industrial waste was generated in 2018. Setting up an effective recycling process can significantly make your business more sustainable.
What are the next steps for making supply chains more sustainable?
- A good first step is to understand your business’s carbon emissions and energy usage.
- Conducting an environmental systems management audit that assesses energy usage, supply chain, and manufacturing processes is a good place to start.
- You can access a range of carbon footprint calculators and sustainability visualisation tools to begin the process of recording, measuring, and monitoring carbon emissions.
