The incident happened at around 7.40pm on Sunday, 29 May, and residents were advised to keep their windows and doors closed.
Hampshire Fire and Rescue Service sent four engines and 20 firefighters to tackle the blaze.
Waste management company Veolia has promised a “full investigation” following the incident.
A Veolia spokesperson said: “We can confirm on the evening of Sunday, May 29, emergency services were called to attend a fire at Blue Haze landfill site. There were no injuries to people or damage to property.
“We take all health and safety issues very seriously and have begun a full investigation into this matter.”
Blame
Councillor Michael Thierry, mayor of Ringwood, said: “As a society we always want to blame someone and get out the hanging nooses, but in certain cases there is no one to blame.
“I have confidence in Veolia – I have been to many of these sites and I know they are well managed, but the incident is regrettable.”
Large plumes of smoke were seen coming from the site on Sunday night. Residents in Ashley Heath and Verwood were advised by the fire service to close their windows and doors.
This warning was not lifted until around 11am the following morning.
Frequency
A Hampshire Fire and Rescue Service spokesperson said: “It is quite common at these sites when it gets hot that rubbish could ignite. We get called out to these incidents at least once a year.”
There have been a number of other incidents at the site in the past five years.
Dozens of firefighters were involved in tackling a blaze at Blue Haze landfill, which had spread across two acres in July 2014 – and a similar sized fire broke out at the site three years ago.
A fire at Blue Haze took almost 24 hours to put out and involved around 500 tonnes of rubbish in 2011.
