Maximizing Sustainability and Fiber Recovery in Molded Pulp Production with Daniel Richards
Molded pulp products, such as food and electronics packaging, are eco-friendly and made from recycled materials. However, their production process can be resource-intensive, requiring significant water and energy use. Similar to other manufacturing processes, molded pulp production needs innovative solutions to minimize its environmental impact and enhance operational performance.
In a recent interview with Daniel Richards, a business development manager at Kadant Solutions since 2021, he highlighted the RotoFlex™ resource recovery strainer and its role in addressing filtration challenges in molded pulp production. By recovering fibers that would otherwise go to waste, the RotoFlex resource recovery strainer helps manufacturers reduce waste disposal costs and dependence on fresh raw materials, aligning with environmental and economic goals.
KB: How does the RotoFlex resource recovery strainer work?
DR: The RotoFlex resource recovery strainer separates and recovers solids using hydraulic pressure and centrifugal force, making it more efficient and user-friendly. Its sloped design allows reclaimed fibers to return to a usable form without constant cleaning, eliminating the need for an electrical hookup and reducing maintenance. Unlike traditional gravity strainers, the RotoFlex resource recovery strainer does not require a continuous cleaning shower, enhancing its efficiency and ease of use.
KB: What problems does the RotoFlex resource recovery strainer solve for molded pulp manufacturers, and how does it support sustainability?
DR: The RotoFlex resource recovery strainer is ideal for systems with high solids content, where traditional methods fail. It addresses issues like clogged nozzles, dirty forming screens, and effluent Biochemical Oxygen Demand (BOD) violations. Recovering fiber and reducing solid loading on effluent treatment equipment improves machine cleanliness and production efficiency. Additionally, by reclaiming water, heat, chemicals, and fibers, the RotoFlex resource recovery strainer reduces waste and conserves resources, helping manufacturers minimize their environmental impact while enhancing operational performance.
KB: How does the RotoFlex resource recovery strainer impact product quality and costs?
DR: The RotoFlex resource recovery strainer improves screen cleaning between molds, enhancing product quality and consistency. It boosts performance, reduces downtime, and extends equipment life. Reclaiming fibers lowers operational costs and supports environmental goals. Maintenance involves replacing the center bushing and media without critical motors or gearboxes. The flow rate is set during initial testing and requires minimal adjustments after installation.
KB: How do you ensure the effectiveness of the RotoFlex resource recovery strainer, and what is its future in molded pulp manufacturing?
DR: We ensure effectiveness by analyzing a five-gallon water sample for solids and determining the appropriate flow rate. The mesh size of the media and throughput volume influence particle removal efficiency. The RotoFlex resource recovery strainer will be crucial for process water filtration, fiber reclamation, and effluent pre-treatment. Its ability to lower BOD levels and reclaim fibers will help manufacturers improve environmental and economic efficiency.
Daniel emphasizes that the RotoFlex resource recovery strainer provides significant environmental and economic advantages, helping manufacturers meet their sustainability and financial objectives. Kadant Solutions is a leader in industry innovation with products like the RotoFlex resource recovery strainer, promoting sustainable and efficient production practices in molded pulp manufacturing.
