Some examples of our work

A dietary pattern that is healthy for both Belgians and the planet

WWF launched the European Eat4Change project to make young Europeans aware of ways to develop and adopt a healthier and more sustainable diet. Our current food system has a substantial environmental impact. As part of this European project, on behalf of WWF Belgium, we analyzed which products fit in a sustainable healthy diet for a family of four. We did this using our software tool Optimeal. The results show that a sustainable and healthy diet is also a little cheaper than the average Belgian's current dietary pattern.

Methodological exploration by Blonk and DSM

Together with DSM we set up a methodological study, by way of road testing, to explore the applicability of sector Life Cycle Assessment (LCA) guidelines, such as FAO LEAP and European Commission Product Environmental Footprint (EC PEF). In APS-footprint we modeled nutritional interventions, specifically the use of feed additives, and explored the effects. The study was externally reviewed by experts, according to the ISO 14044 LCA guidelines.


APS-footprint is a software solution that helps you define and monitor more sustainable animal production systems and reduce their environmental impact. It includes complete life cycle assessment (LCA) functionality and generates comprehensible results. These results can be used for research & development, monitoring innovations, CSR or sustainability reporting and communication.

Understanding Avebe’s environmental product performance

Avebe is a cooperative of starch potato growers focusing on extracting starch and proteins from potatoes. Avebe’s customers use these ingredients in food products and cattle food or industrial applications. Sustainability is an important objective for Avebe. Blonk Consultants worked with Avebe to develop a life cycle assessment (LCA) model to calculate the environmental footprint of each product in the company's portfolio.

HortiFootprint Category Rules

There didn’t exist an up-to-date standard methodology to calculate the environmental impacts of horticultural products, like fruits, vegetables, flowers and plants. To meet consumer and industry stakeholder demands for environmental impact information, in 2018, a project was started to develop uniform calculation guidelines to be accepted across the whole horticultural value chain and in line with European directives. Blonk was part of the project team and involved as an expert.

LCA standard for Growing Media Europe

Growing Media Europe (GME) is an international non-profit organization representing the producers of growing media and soil improvers at European level. Growing media are materials other than soil in situ in which plants and mushrooms are grown. For GME Blonk developed an uniform LCA Toolbox, in line with the European PEF method. A ‘task force’ of expert industry advisers were involved the development of the LCA standard.
