Nicholas Willenbrock
Nicholas manages the development of the Definition of Waste: Development Industry Code of Practice
(DoW CoP) – a hugely successful, co-regulation approach to excavated soils reuse.

Alongside this, he has developed CL:AIRE''s online ''Register of Materials'' which successfully matches projects with surplus soils to those with a deficit. He has also helped foster the International Group of Excavated Materials Reuse Programs – which aims to link soils reuse initiatives in France, Belgium, The Netherlands and Canada to share lessons learnt and development ideas.

Most recently, Nicholas led the auditing and review process on behalf of the UK Regulator and led the first research into the benefits of soil reuse through sustainability assessments of real projects.
