As one of the world’s leading clinical trial logistics companies, sustainability is a major focus for us at GNN Group. We are actively committed to reducing the environmental footprint of our logistics processes while ensuring high efficiency and high quality.

Key aspects of sustainability include reducing waste and precluding disposable packaging and disposable loggers. Instead, we count on reusable thermal packaging. This packaging can be cleaned and reused after each shipment, which not only reduces waste but also cuts down on costs. We work with well-known manufacturers of reusable packaging in order to provide our customers with an optimal solution for their needs.

Reusable packaging is one of the many ways we make an important contribution toward reducing carbon emissions. Disposable packaging usually necessitates costly disposal and cannot be reused. Reusable packaging, on the other hand, conserves raw materials and energy and reduces environmental impact. Another important factor for sustainability in clinical trial logistics is the transport route.

We cut down on carbon emissions by optimizing transport routes and using environmentally friendly shipping methods such as electric cars and bikes. The use of alternative transportation options such as shipping via rail or sea also helps minimize our environmental footprint.

When it comes to the storage of samples and medicines, we rely on energy-efficient technologies and an efficient organization. Optimized warehousing can save energy while also improving the shelf life and quality of products. We also account for environmental conditions when selecting warehouse sites, such as when we need to consider energy-efficient air conditioning.

In addition to environmental sustainability, social sustainability also plays an important role in the logistics of clinical trials. We strive to create fair working conditions for our employees and partners, and we are committed to respecting human rights and protecting sensitive data. In support of these objectives, we work closely with our customers and partners to ensure responsible and sustainable teamwork.

We are proud to be a company that is committed to sustainability in clinical trial logistics. By using returnable packaging and optimizing our transport and warehousing processes, we help reduce our environmental footprint while ensuring the highest quality and efficiency. We are convinced that sustainable logistics is beneficial not only for the environment, but also for our customers and partners.
