Welcome to this landing page of www.efmanbv.nl.

Efman BV is founded in 2007, being a shortening of “Effective Management”. From my perspective one should come to

sustainable results, aiming for ‘effectivity’, prior to ‘efficiency’.

During 2007 and 2008 Efman BV provided Senior Project management services on a full time basis. On part-time basis

Efman initiated real estate projects in 2014 and 2017, and prepared an Unsolicited Proposal to valorize spent acid waste

for the chemical industry in 2018.

Over the last 8 years, I have been active in Business Development for reputable companies, mainly for biogas production

by digestion or gasification. Others: heating networks (district/industrial), heat storage, hydropower (tidal, rundown).

As of March 2024 I caught up activities for Efman on a full-time basis.

Please contact me for further information if you may require any support in the broad field of renewable energy asset

development. Please consider any early adoption, (pre)feasibility studies, Business Plan assessment and evaluations,

innovations as of TRL 7, (new) feedstock assessments, trouble shouting, etc.
