• Eminox was established in 1978
• We employ around 220 people in 6 countries
• We design and manufacture exhaust and emission control systems for heavy duty diesel engines
• We have supplied approx. 70,000 emission control systems to date
• Our systems are used across Europe and further afield forAir Quality clean up programmes
About Eminox

City Pollution
• Particulate Matter (PM) and Nitrogen Oxides (NOx) are damaging to health and the environment
• Many cities across Europe are failing to meet legal limits for PM and NO2
• There is no safe limit for exposure to PM (World Health Organisation)
• The link between black carbon (PM) and global warming is now internationally recognised

Retrofit
• New vehicles are now manufactured with technology that reduces their emissions of PM and NOx
• There are many older buses still in service – reducing pollution from these buses can have a major impact
• These can be retrofitted with emissions reduction systems at a fraction of the cost of new buses
• With SCRT technology 15 buses can be upgraded to Euro V for the cost of 1 new bus

Eminox SCRT has been used inEurope’s largest retrofit programmes
• Belgium - 247 buses upgraded for bus operator DeLijn
• Spain – More than 400 buses upgraded in Barcelona
• Sweden – around 300 systems fitted to meet local traffic emissions requirements for PM and NOx
• Edinburgh - 43 Lothian buses upgraded
• Oxford – 26 systems fitted

SCRT® System
• Combines two technologies:
CRT® (Continuously Regenerating Trap)
SCR (Selective Catalytic Reduction)
• Same technology as used for Euro V, EEV and Euro VI
• Advanced emissions technology reduces • particulate matter• nitrogen oxides• hydrocarbons• carbon monoxide

SCRT® System
• Vehicles as old as Euro II can be upgraded to the latest Euro V emissions standards
• This requires71% reduction in NOx86% reduction in PM
• In independent tests the Eminox SCRT achieved equivalent reductions
