The Ecoflo® biofilter : contributing to the quality of water resources

Premier Tech operates in industries with the potential to develop products and services that generate a positive impact and help address current environmental and social challenges.

By establishing our sustainability position, we reaffirmed our commitment to innovation and the development of impactful products and services. We have also outlined specific criteria to define what qualifies as such:

The offer addresses a social or an environmental challenge in a precise or tangible manner
The offer is integrated and designed for a long-term impact
The offer is verifiable and quantifiable

These criteria enable us not only to measure the positive impact of our commercial offers, but also to better identify and evaluate those we aim to develop. It ensures transparent communication regarding the benefits of our impactful commercial offers and business models.

Thirty years ago, we developed a product that remains a flagship brand at Premier Tech: the Ecoflo® biofilter. Here is how it concretely aligns with our three criteria for an impactful offer.

Criteria 1

The offer addresses a social or an environmental challenge in a precise or tangible manner

We evaluate the purpose of a product to determine if it addresses a recognized and documented environmental or social challenge. To do so, we refer to the established international framework: the Sustainable Development Goals (SDGs) of the United Nations. We also base our key performance indicators on the IRIS+ system, a positive impact measuring tool designed for businesses.

Our offer

From its design to its commercialization, the Ecoflo® biofilter reflects our long-standing commitment to protecting health and enhancing the quality of our water resources. Its design and filtering medium, made from peat moss and coco husk fibre, enable the Ecoflo® biofilter to treat and release wastewater in an environmentally safe manner, thus ensuring the protection of sensitive ecosystems.

Moreover, unlike most comparable products on the market, its filtering medium consists of natural fibres that do not require chemical additives, making it compostable at the end of its life cycle.

Focused on environmental performance and greater autonomy in the manufacturing of its components, the Ecoflo® biofilter represents a sustainable solution for current water resources management challenges. It also actively contributes to achieving SDG 6, which calls for sustainable water management and treatment.

Criteria 2

The offer is integrated and designed for a long-term impact

We evaluate whether a product or service is embedded and established as part of the commercial offer of our Business Groups. We aim to identify offers and models that create a positive and lasting impact.

Our offer

For over 30 years, the Ecoflo® biofilter has been a cornerstone of Premier Tech Water and Environment, providing sustainable wastewater treatment solutions to homeowners and communities. From the beginning, it secured a strong foothold in the market through sustained investments in Innovation, Research and Development, positioning itself as a benchmark in wastewater treatment.

Over the years, the biofilter has continuously evolved, driven by a clear ambition: to provide a compact, high-performance, eco-responsible and lasting solution to protect water resources. From the continuous improvement of components and optimization of performance to the integration of new renewable filtering materials, each advancement reflects our unwavering commitment to quality, innovation and sustainability.

Criteria 3

The offer is verifiable and quantifiable

We ensure that the positive impact of our offer is quantifiable and verifiable. We aim to demonstrate, with appropriate context and supporting evidence, how our products and services create a positive impact on the environment or address a social challenge. Committed to transparency, we seek to provide reliable and detailed evidence to all our stakeholders.

Our offer

In every country where it is sold, the Ecoflo® biofilter must undergo rigorous certification processes to verify filtering performance. These certifications are more than mere formalities, they confirm that our offer protects the environment and meets the highest standards, even in sensitive environments.

Its quality and reliability are further demonstrated by studies validating its effectiveness in treating or reducing contaminants. Life cycle analyses also enabled us to measure its environmental footprint, positioning the Ecoflo® biofilter as one of the systems with the lowest carbon footprint in the industry.

This constant commitment to transparency and quality ensures that the positive environmental impact of our offer is both verifiable and quantifiable. With more than 200 000 units installed in various countries, the Ecoflo® biofilter is a symbol of eco-performance, quality and sustainability.
