Cobra has hit back following its £25,800 fine for failing to comply with recycling regulations.
Cobra business development director Christopher Edgcumbe-Rendle said: "At Cobra Beer we take our environmental responsibilities extremely seriously.
"It is clear that, during the period 2003-05, we did not take the necessary steps to engage with the Environment Agency to meet all of our obligations, for which we apologise unreservedly.
"Since being made aware of the situation, we have co-operated fully with the Environment Agency and joined an Environment Agency accredited compliance scheme to ensure we now meet all Producer Responsibility Obligations."
He added that an internal review conducted by the company has led to appointing a full-time operations director and operations team to ensure that Cobra's waste management policies 'go even further to fulfil our genuine commitment to environmental responsibility'.
The company pleaded guilty on Thursday to failing to register with the Environment Agency as a producer of packaging, and to failing to meet its requirements to recover and recycle packaging waste - which businesses with an annual turnover above £2m must do under the Producer Responsibility Obligations (Packaging Waste) Regulations.
