GMP: Good Manufacturing Practices

Getting everything from waste streams does not mean we work irresponsibly. We want to add value and manage costs, but never push things beyond the acceptable. Our GMP-certificate confirms this. We work with care for society and environment.

Why dry and separate food?

  • To increase shelf-life
  • To destroy bacterial pollution
  • To combat fungi
  • To prepare for external final processing
  • To upgrade product quality
  • To transform from waste to resource

GMP, a safe idea

What remains after drying and separating for further or final processing, is guaranteed to meet the legal requirements. Moreover, we strictly produce according the effective agreements between industry partners and customers. Our proof is the GMP-certificate, registered under number 20233. A safe idea.
