Revolutionising the Bus Industry: How Sustainable Parts Cleaning is the route to Net Zero

Updated: Feb 13

The bus industry is undergoing a major transformation, fuelled by the urgent need to reduce carbon emissions and the target of net zero by 2050, and combat climate change. One key area that is revolutionising this sector is sustainable parts cleaning. By adopting low environmental cleaning practices, bus companies are not only reducing their environmental footprint but also cutting operating costs and improving overall efficiency.

In this article, we delve into the ways sustainable parts cleaning is driving decarbonisation in the bus industry. From utilising clever cleaning systems based on bioremediation, low VOC emissions and reduced waste, operators are taking proactive steps to ensure a cleaner and greener future. These sustainable cleaning practices not only help reduce harmful emissions released into the environment but also enhance the longevity and performance of bus parts, resulting in significant cost savings and extended lifespans for vehicles.

Join us as we explore the innovative initiatives and technologies that are transforming the way buses are cleaned and maintained. Discover how sustainable parts cleaning is becoming a powerful driver of change for the bus and coach industry.

The importance of decarbonisation in the bus industry

Decarbonisation is a critical goal for the bus industry as it aims to reduce carbon emissions to net zero by 2025 and mitigate the impacts of climate change, as part of the UK's Transport Decarbonisation Plan. Buses, especially those powered by fossil fuels, have traditionally been a major contributor to air pollution and greenhouse gas emissions (although certainly lower than other modes of transport). By embracing sustainable parts cleaning, bus companies can significantly reduce their carbon footprint and contribute to a cleaner environment.

Sustainable parts cleaning not only improves air quality but also has a positive impact on public health. Reduced emissions mean fewer harmful pollutants in the air, leading to a decrease in respiratory illnesses and other health issues associated with air pollution. Additionally, adopting sustainable practices helps bus companies comply with recent but essential environmental regulations and demonstrates their commitment to sustainability.

The challenges of traditional parts cleaning methods

Traditional parts cleaning methods involve the use of chemicals and solvents that are harmful to the environment and human health. These chemicals can contaminate soil and water sources, leading to long-term environmental damage. In addition, the disposal of hazardous waste generated during the parts cleaning processes poses additional challenges.

Apart from environmental concerns, traditional parts cleaning methods are time-consuming and costly. Cleaning parts manually or using outdated equipment can result in increased labour costs and inefficient processes. This not only impacts productivity but also limits the ability of bus companies to scale their operations.

The benefits of sustainable parts cleaning

Sustainable parts cleaning offers numerous benefits to the bus industry, ranging from environmental to financial advantages. By switching to aqueous surface technology systems, bus companies can effectively reduce their carbon footprint. Aqueous parts cleaning systems such as the BIO-CIRCLE range of parts washers are a direct alternative to solvents based parts cleaning systems. They harness the power of bioremediation to effectively remove grease, oil, dirt, glue, dust, paint and many more contaminants from parts, engines, tools and surfaces. Low VOC or VOC-free cleaning solutions are used in conjunction with the parts cleaning systems mean reduced VOC emissions, reduced waste and improved health and safety - without compromising on cleaning performance.

Along with the environmental benefits, sustainable parts cleaning also improves the performance and longevity of bus parts. By using gentle yet effective cleaning solutions, companies can prevent corrosion and damage to critical components with a robust parts maintenance programme. This results in reduced maintenance costs, increased reliability, and extended lifespans for the buses.

Sustainable cleaning practices also promote water conservation. Our advanced cleaning systems such as BIO-CIRCLE EKO minimises water consumption and wastewater generation. It directly replaces pressure washers. This not only helps conserve water and reduces the strain on local water supplies, it also prevents hazardous wastewater run off.

Case studies of successful decarbonisation in the bus industry

1. The maintenance & cleaning of bus and tram engines at bus company's depots was carried out by solvents based parts cleaners. There was a high exposure to solvents, a short service life of the cleaning liquids, indoor air pollution, hazardous waste, unpleasant odours etc. We replaced the solvents based parts cleaners with the BIO-CIRCLE GT Maxi and HP Vigo with our VOC-free cleaning liquid L-EVO. The operator found more efficient and pleasant cleaning processes, a decreased health risk to the mechanics along with a reduced waste chain - all contributing to decarbonisation targets.

2. Another customer replaced their energy guzzling solvent-based cleaners and machines with the BIO-CIRCLE GT Maxi and the HTW systems with the VOC-free cleaning liquids L-EVO and Alustar 300. Their main cleaning focus was the filter housing, oil separators, oil pans and camshafts. The result was a much happier workforce using the low-risk cleaners, with a hugely reduced environmental impact and more pleasant odours. The cost of compliance and the storage costs of cleaners was also minimised, and much less cleaner was needed to be used over the same period of time due to the clever self-cleaning technology of BIO-CIRCLE cleaners.

Implementing sustainable parts cleaning in your bus fleet

If you're looking to embrace sustainable parts cleaning and optimise your cleaning processes, there are several steps to take to get started. First we'll carry out an audit of your current cleaning processes to identify areas for improvement. We'll assess the environmental impact, efficiency and costs of your cleaning systems and liquids, and advise on a process optimisation & decarbonisation plan.

Our cleaning systems and technologies enhance our customer's efficiency and reduce resource consumption and hazards. We will work with you to ensure you are on the route to net zero in your surface and parts cleaning processes, with bespoke strategies that are individually tailored to your specifications and needs. We are not a one size fits all operation!

The future of sustainable parts cleaning in the bus industry

Sustainable parts cleaning in the bus industry isn't going away. In fact, as technology continues to advance, we can expect even more innovative solutions to emerge. From the development of new clever cleaning solutions to the implementation of machine learning algorithms for optimised cleaning processes, we're excited about the future and the endless possibilities for cleaner & greener cleaning!

As our government and industry regulatory bodies rightly push for stricter environmental standards, bus companies will be compelled to adopt sustainable practices in order to meet decarbonisation goals.

The integration of electric and hybrid buses into fleets will further drive the need for sustainable parts cleaning, as these vehicles and their components require specialised maintenance and cleaning. The bus industry already offers lower environmental impact as a transport modality and by adopting sustainable parts cleaning and replacing old, hazardous parts cleaning equipment, bus companies can work towards their environmental goals while reaping the financial and health co-benefits associated with improved efficiency, reduced hazards and reduced maintenance costs.


Sustainable parts cleaning is changing the way the bus industry cleans, playing a supporting role in decarbonisation, and paving the way for a cleaner and greener future. By embracing non-hazardous cleaning practices, bus companies can significantly reduce their carbon footprint, improve operational efficiency, and extend the lifespan of their vehicles.

With the integration of innovative technologies and the support of industry partnerships, the bus industry is well-positioned to lead the way in decarbonisation efforts. Let us work together to create a sustainable and thriving bus industry that benefits both the environment and future generations. Contact us now to arrange your free site survey.
