Context

What is the interview about?

In the JAJO interview (29 March 2023, Kompas series), Pepijn Duijvestein describes how conventional material use gives way to biobased and regenerative material use. New Economy maps the impact of a change on CO₂ and ecosystems, and calculates how much interventions may cost. The starting point is a single reversal: production processes are adjusted once, after which materials remain usable again and again.

The interview connects material choices with social cost-benefit analyses in tenders, with health through the indoor climate of buildings, and with shared ownership. The Co-Operate project experiments with shared ownership models that match the circular ambitions of neighbourhoods and the wellbeing of residents.

From the interview

What does Pepijn Duijvestein say?

The interview centres on value that goes beyond profit alone. Materials are seen as a living stock, and buildings as places that keep that stock. Profit is not an aim in itself.

“Profit often comes at the expense of something or someone.” — Pepijn Duijvestein
