Work continues to clear the site of a vast stack fire near Silk Willoughby on Sunday.
About half of 24,000 bales meant for the Sleaford Renewable Energy Plant (REP) were affected in the blaze.
Speaking yesterday (Tuesday), Mike Harrison, communications manager for the plant, said: “It has been over a week since the arson attack on one of our storage sites near Sleaford.
“Since the incident most of the remaining stock has been removed from the site with just approximately 3,000 bales left and isolated from the remnants of the fire.
“These will be removed shortly.
“We are also removing loose straw and degraded materials which is currently being received by a large landowner for use as compost.”
Mr Harrison added that Sleaford REP is also meeting the Lincolnshire Joint Fire Task Force shortly to discuss the incident and the other strategic storage sites it operates.
He said: “This will include reviewing all operational plans and emergency response planning as is normal under these circumstances.
“We want to be good neighbours and do have positive relationships with local councillors and organisations.
“Therefore we would like to apologise for the inconvience caused to the public by the fire including the closure of the A15.”
Three boys arrested on suspicion of arson, as of yesterday afternoon, remained on police bail.
