Cleaner Buses in the UK

The reduction of nitrogen oxides (NOx) and particulate matter air pollution remains to be one of the hottest issues relating to urban public transport and inner city air quality in the UK. In September 2012, the International Agency for Research on Cancer reclassified diesel engine exhaust emissions as carcinogenic to humans, reassigning it to the same class of hazardous materials as asbestos, arsenic and mustard gas.

The majority of large towns and cities in the UK are failing to meet stringent European requirements for NOx emissions and the Government is faced with significant financial penalties as a result of this failure.

To help combat these penalties, the Department for Transport continues to provide funding for air quality improvement projects throughout England. Local authorities are invited to work with public transport providers to bid for a share of this fund to be used to clean up on (NOx) emissions generated by transportation. The authorities concerned are encouraging operators to cooperate and view such schemes as a voluntary alternative to the compulsory introduction of LEZ’s throughout England.

HJS are pleased to reveal that we are working with several major operators and local authorities to improve regional air quality as part of the first CBTF/CVTF initiatives in 2013/4. We are currently engaged in projects in The Midlands, South Yorkshire, London, Bristol, Bath and Southampton. We are delighted to reveal that we have recently delivered a 99% reduction in NOx emissions during Millbrook tests on a School bus for the North West of England. HJS are also contributing to clean air in the City of Oxford and have retrofitted a quantity of Euro 2 vehicles which now exceed Euro 5 emissions standards!

Urban transport providers play an extremely important role in securing this funding and they are requested to pioneer new technologies and modernise their bus fleets. Fortunately for all concerned there are more cost-effective ways of reducing emissions than buying brand new vehicles. HJS are pioneers of and patent holders of Selective Catalytic Reduction Technology (SCRT) which can be retrofitted to allow authorities and operators to significantly reduce bus NOx emissions and also virtually eliminate particulate matter.

HJS employ more than 450 people at our plant based in Menden, near Dortmund in Germany. We have a dedicated UK sales and technical team who provide a nationwide installation service with support coordinated from our facility based in Bracknell, Berkshire. Our principal installation teams are experienced OEM trained technicians who are able to plan and implement an installation schedule to suit your needs and operational requirements.

HJS are manufacturers of OE quality emission abatement systems for cleaner and greener diesel emissions. Designed and manufactured to the standards you would expect in Germany.

If you are a bus operator or a local authority and would like to know more then please contact our UK office.

The Greater London Authority and Construction LEZ for NRMM

From the 1st of September 2015 the Greater London Authority (GLA) is set to introduce a Low Emission Zone which will affect a large number of construction machines being used within the Capital. With an estimated 10,000 active construction sites in London at any one time NRMM has been identified by the GLA as one of the largest contributors to poor air quality in London.

In 2010 construction activity was responsible for 12% of NOx emissions and 15% of fine particulate (PM10) emissions in Greater London.

The Supplementary Planning Guidance will be introduced from September 1st 2015 and will apply to all NRMM with a net power rating of between 37kW and 560kW and the minimum emission standards for NRMM within London are detailed below:

    • NRMM used on the site of any major development, as defined in the London Plan within Greater London will be required to meet emission Stage 3A as a minimum
    • NRMM used on any site within the Central Activity Zone or Canary Wharf will be required to meet emission Stage 3B as a minimum
    • All eligible NRMM should meet the standards above unless it can be demonstrated that a comprehensive retrofit to meet both PM and NOx emission standards is not feasible. In this situation every effort should be made to use the least polluting equipment available including retrofitting technologies to reduce particulate matter emissions

Plant hire companies, construction organisations and machine operators have been advised of their limited options:

    • Retrofit existing machines with emission abatement technologies
    • Reorganise NRMM fleet to ensure compliant equipment is used
    • Replace or re- engine equipment

For the majority of operators the retrofitting of existing machinery will be the quickest, most effective and most reliable way of ensuring that they comply by the 1st of September.
