BLOG: Sponsor Spotlight Q&A - Power Knot

Iain Milnes, president of Power Knot, spoke with Seatrade Cruise Global and answered some questions about the LFC biodigester, and why food waste digesters are an essential decarbonization tool for cruise ships.

Q: How does your product/service benefit the cruise industry and what sets it apart from the competition?

A: Our flagship product, the LFC biodigester, revolutionizes waste management on cruise ships. The machine uses microbes to eat organics and turn it into grey water, eliminating the need to store or pulp food waste. The machine’s design prevents plastics from entering the waste stream. By efficiently disposing of food waste in an eco-friendly manner, we help preserve the ocean and combat plastic pollution. What sets us apart is our commitment to creating a sustainable ecosystem of products specifically tailored for the cruise industry, ensuring long-term environmental benefits.

Q: What do you see as your biggest challenge within the industry in the coming year?

A: Our biggest challenge lies in encouraging older ships to adopt sustainable practices like integrating the LFC biodigester. While newer builds are increasingly incorporating eco-friendly solutions, existing vessels are more resilient to changes.

Q: What are you hoping to achieve by sponsoring at Seatrade Cruise Global 2024?

A: Our goal at Seatrade Cruise Global 2024 is to democratize technology and raise awareness about innovative solutions for reducing food waste onboard. By showcasing our products, we aim to make a tangible difference in helping ships decarbonize and embrace sustainable practices.

Q: Describe any concrete steps your organization is taking to improve sustainability in cruise?

A: We're actively working to replace outdated pulpers with our LFC biodigesters, eliminating the need for traditional waste disposal methods. Additionally, we're continuously innovating and collaborating with industry stakeholders to develop new sustainable solutions for cruise ships.

Q: What does sustainability mean to your company?

A: Sustainability is at the core of our company ethos. It's about more than just products; it's a commitment to preserving the environment, minimizing waste, and fostering a greener future for the cruise industry and beyond. Our entire business model revolves around sustainability, driving us to innovate and advocate for eco-friendly practices at every opportunity.
