This paper applies the concept of "Product as a Service" (PaaS) to the filtration industry. The traditional filtration business model does not sufficiently incentive manufacturers of filters to reduce energy consumption, CO₂ emissions and waste generation in the downstream of their value chain.

Filtration as a Service (FaaS) offers a transformative approach by shifting from product-based to service-based models, thereby enabling more efficient resource utilization and reducing ecological footprints.

We focus on two key performance indicators (KPIs): (1) generated waste and (2) CO₂ emissions, to evaluate the environmental benefits of FaaS. Through a comprehensive analysis, we compare conventional filtration systems with FaaS implementations with a focus on hydraulic filtration applications. The study reveals that FaaS can substantially lower the volume of waste produced by optimizing filter usage, maintenance, and disposal processes. Additionally, the service model fosters more efficient energy consumption and logistics, leading to a reduction in CO₂ emissions.

Our findings indicate that adopting FaaS not only supports the sustainability goals of organizations but also contributes to broader environmental objectives by mitigating pollution and conserving resources. This paper provides actionable insights and strategic recommendations for businesses aiming to transition towards more sustainable filtration solutions.
