CAL International founder Cliff Kirby explains partnership with AirSeed Technologies


A partnership between CAL International and AirSeed Technologies aims to plant 100 million trees by 2024. This will tackle deforestation and help in the major fightback against global warming.

AirSeed Technologies co-founder Andrew Walker approached CAL International to assist in refining the planting systems for their drone technology. Commenting on the project, CAL International founder and engineer Cliff Kirby said, “As soon as Andrew mentioned AirSeed to me, I knew we were talking about a product and project that was ground-breaking in every sense of the word.”

“CAL International is a unique business that not only has dedicated teams working in partnership Blue Chip manufacturers but also incredible start-up technologies and disruptors such as NeedleSmart and AirSeed,” Kirby continued. “As a company, we blend a traditional engineering background with a company ethos built on innovation.”

“As such, we are often brought in to solve complex problems and issues in the automotive, defence and nuclear industries,” the CAL International founder added. “Often, those complexities will span both engineering and tech fields, which allows us to create solutions that can then be scaled to volume. ”


Headquartered in Sydney, Australia with a secondary satellite office in Cape Town, South Africa, AirSeed Technologies was founded by Walker and South African data-mapping analyst Andries Louw. CAL International is based in Knowsley, Merseyside, England, United Kingdom.

“When AirSeed explained what they hoped to achieve, it was a challenge that we were delighted to take on,” Kirby said. “The huge significance and impact that this innovation can bring in the fight against climate change is truly global. Together with AirSeed based in Australia and South Africa and CAL based in the UK, this is a global collaboration and the very definition of the art of the possible.”


Using artificial and data intelligence, the AirSeed drone identifies and locates designated target areas with global positioning system (GPS) coordinates and then fires carbon pods onto the ground at a rate of two-per-second. The carbon pods are then pinpointed on the mapping system in line with the flight trajectory, which also considers wind variables and conditions on the day of planting

“The collaboration between CAL and AirSeed will ultimately mean that each drone can deliver two pods per second over a designated area, planting up to 40,000 pods in a day,” Kirby explained. “Through rapid automation and scale of the process, it can cover and penetrate a much wider geographical area.”
