Managing logistics and monitoring deliveries
Coordination and sourcing of Serbian origin goods

I believe organic production is of great importance, not only for environmental sustainability but also for ensuring high quality, transparent and responsible products. It represents a long term commitment to both consumers and the planet and plays a key role in building trust across the entire supply chain.

I am responsible for overseeing all aspects of logistics while also supporting the purchasing of Serbian origin goods, ensuring smooth operations and strong collaboration with our suppliers and customers.

Quality assurance/ Quality systems

“I work in an organic organization because I appreciate the role of organic agriculture in maintaining environmental health.”

I coordinate risk assessments and approvals of suppliers based on documentation and implemented procedures, as well as harmonize customer requirements regarding quality parameters of products that are the subject of trade. I monitor and coordinate the full supply chain process of verification of chemical analysis parameters and the lab analyses.

Sales/Purchase and Political Affairs

“I believe the values of the organic sector are worth nurturing and protecting, and that is partly political as well.”

I do sales and purchase, as well as the external communication of NaNa Bio B.V. and its oftentimes political messages to the outside world. I coordinate and develop political programs that are rooted in the values of NaNa Bio B.V.

Farmers

Farmers are the backbone of all of our organic products. We are connected to thousands of farmers all across the world. We are specialized in dealing with smallholder farming systems in which organic pays out immediately, to improve livelihoods and lives of farmers.

Processing partners

Without our processing partners, we cannot ensure good quality end products. They make our purees; they freeze our fruits and press our juices. We have long-term relations with certified state of the art factories worldwide.

Other service providers

We work together with so many different stakeholders in this field that are oftentimes made invisible. We see the supply chain as a living organism. Without these following stakeholders, nothing happens. They are daily occupied to make operations work to get you the best quality of organic fruits.

Certification bodies, laboratories, service providers, custom clearance, importing, storage, transporters, marketing and communication, ICT, accountants, insurance, umbrella organizations that support us, Triodos bank, colleague competitors, teachers and trainers.
