A-1 Environmental Services is aware of its duty towards the environment and strongly advocates recycling. We recycle almost a million litres of oil a year, along with used plastic oil containers, used motor oil, and filters. A single litre of used oil can contaminate a million litres of groundwater. That is why we encourage people to ensure that every drop of used oil, filter, and container is returned to a collection facility during regular hours so it can be disposed of properly.
