More than 800 cars were clocked through the two drop off points for this year's HazMobile collection in Hastings and Napier over the weekend.
The initiative gave people the opportunity to hand over hazardous waste. Some of the material collected included garden chemicals not available for over 50 years.
Hastings District Council waste minimisation planner Angela Atkins said there were 422 cars through the Hastings Sports Centre depot in Hastings on Saturday and 417 at the Eastern Truck and Marine site, Onekawa, Napier on Sunday.
"We received some highly toxic material so it's great to get that stuff out of the environment using the correct process. We had paints, chemicals and older garden chemicals not around since the 1950s and 1960s," says Ms Atkins.
"There is still a lot of that stuff coming out each year and at least this gives people a chance to get rid of it, no questions asked."
Other items included lights, paints, florescent tubes, batteries, automotive products like waste oil, petrol and car care products.
The chemicals collected would go to Chemwaste Industries in Auckland and the material which can't be recycled would go overseas to be correctly disposed.
Gas bottles would be recertified and resold in Hastings and those that could not be used again could be turned into scrap metal. Solvents, waste oil and automotive fuels would go to Beards Environmental in Hastings to be recycled.
Ms Atkins said a team of volunteers from the Heretaunga Tramping Club worked at the collection points to help collect the waste material from cars.
"It was a very successful weekend and from the response we got, we will definitely continue to hold the collection next year."
Ms Atkins said HazMobile was also supported by Napier City Council and the Hawke's Bay Regional Council.
