Most natural resources are in limited supply, and to minimise unnecessary waste, COLLET has decided to invest in a number of hi-tech, environment-enhancing solutions. Here are a few examples:

• We heat all buildings and rented accommodation at Lundbygaard using wood pellet fuel in a computer-controlled, CO₂-neutral wood pellet furnace with a high efficiency level.
• We have introduced GPS and computer-controlled fertilizing equipment and sprayers to ensure precise delivery and reduce the use of plant nutrients and plant protection.
• GPS-connected and controlled planting machines for Christmas trees makes the best use of the land.
• We have patents for selectively bred plants that are more resistant to disease and thus more environmentally friendly.
