Bamboo refining for giant pandas

ANDRITZ processes bamboo for Vienna Zoo, Tiergarten Schönbrunn, Austria

At the end of 2019, ANDRITZ received an order for an extraordinary project that not only pleased our sales and project managers responsible, but also the entire Mechanical Pulping Team of ANDRITZ’s Paper, Fiber and Recycling division.

ANDRITZ recently processed 500 kg of bamboo for the giant pandas at Vienna Zoo (Tiergarten Schönbrunn). The bamboo flour produced is the main ingredient used in steamed “bamboo bread”, which is needed to supplement the raw bamboo for the 20-year old giant panda Yuan Yuan, who has been in Vienna Zoo since April 2019. However, the female giant panda Yang Yang is also fed the bamboo flour, which is particularly important for female giant pandas when they area rearing young animals.

"The willingness of the ANDRITZ Team to take on the challenge of our bamboo grating problem was a great relief for the whole ‘panda team’ at Vienna Zoo. The way ANDRITZ dealt with this unusual and off-the-normal order was exceptionally kind and professional.”

Dr. Eveline Dungl
Zoological Curator and Animal Trainer

The pre-shredded raw material provided by the zoo was recently processed at the ANDRITZ Stock Preparation Pilot Plant in Graz using a CompaDis disperser. So far, Vienna Zoo had grated the bamboo stems with a special, but small technical device, but then approached ANDRITZ in search of a more efficient way to prepare the food for the giant pandas.

“Although we have experience with all kinds of fibers, producing food for giant pandas was something new for us. The whole pilot plant team is proud of this project.”

ANDRITZ is very proud to be part of such a worthwhile collaboration project and was happy to hear that Yuan Yuan immediately enjoyed his freshly prepared food!

All-round protection for giant pandas

Since 2003, the Vienna Zoo has been one of only a few zoos worldwide to house giant pandas. The threatened bears are the most well-known symbol of species protection. The work of the Vienna Zoo’s panda protection program includes financial support for panda reserves, important research work, and a regular exchange of knowledge on such topics as wildlife management and ecotourism.
