Sustainable production network

IMA, Distilleria Bertolino, and Industria Chimica Valenzana together form a sustainable production network thanks to a continuous collaboration and exchange of resources. This exchange enables the whole Group to achieve an unparalleled efficiency in the valorization of wine subproducts, thus representing a virtuous example of circular economy.

Industria Chimica Valenzana - sustainable production network

Case study: bioethanol

An example of the network’s sustainable success is the production of our advanced bioethanol. From grape marc and wine lees, Distilleria Bertolino and Industria Chimica Valenzana produce, through distillation, row-grade alcohol which is then sent to IMA’s molecular sieve’s plant. The plant processes the alcohol, extracts its water content, and obtains bioethanol.


Due to this production process which exclusively uses wine subproducts, our bioethanol is classified as advanced. In 2021 sustainable bioethanol contributed to a 76% average reduction of greenhouse gas emissions at a European level.


To certify the quality and the sustainability of our products, our plants obtained several certifications which are recognized worldwide.

In particular, IMA certifies its bioethanol’s sustainability with:

  • International Sustainability and Carbon Certification (ISCC-EU)
  • Biomass & Biofuels Sustainability 2BSVS voluntary scheme

Industria Chimica Valenzana has various quality certifications and information documents for Natural Tartaric Acid of agricultural origin:

  • ISO 9001certificate
  • ISO 22000-FSSC
  • Kosher
  • Halal
  • FDA registration
  • Granulometry
  • Product Specification

Distilleria Bertolino guarantees its compliance with RED’s (renewable energy directive) requirements through the: International Sustainability and Carbon Certification (ISCC-EU)
