The case was bought by the Environment Agency which found evidence that De Bortoli had been in breach of regulations between 2005 and 2007, and that by not registering with the agency had avoided paying fees and costs estimated at £5,022.
The company was fined £4,500 by Weymouth magistrates after pleading guilty to nine offences including failure to register, failing to recover and recycle packaging waste and failing to furnish a certificate of compliance.
It was also ordered to pay £2,128 in costs and compensation of £1,686.
Any business handling over 50 tonnes of packaging a year with an annual turnover of £2 million is required to recover and recycle a percentage of the tonnage of packaging they handle.
Companies have to register with the Environment Agency or sign up to a local compliance scheme each year, and provide data on packaging handled.
