<p class="Abstractorclever" style="margin: 0cm; margin-bottom: .0001pt;"><em><span lang="EN-US" style="font-size: 11.0pt; font-weight: normal;">Cardboard is known as a cost-effective and most common material for packing products to keep intact during shipping. Consequently, global paper and board consumption reached a total of 408 million tons in 2021 and is expected to reach 476 million tons in 2032. Due to the large size of the furniture in general, the excessive amount of cardboard required for packaging creates a big problem as the cardboard loses its function after shipment and delivery. Thus, the idea was born of reusing cardboard boxes used in product packaging as shelters for street animals. </span></em></p> <p class="Abstractorclever" style="margin: 0cm; margin-bottom: .0001pt;"><em><span lang="EN-US" style="font-size: 11.0pt; font-weight: normal;">In the present study, the resistance against outdoor conditions of the waste packaging cardboards which considered to used as stray animal shelter were measured and analyzed with BCT, ECT, and COBB 60 tests. As a result, it has been determined that the stray animal shelters that made of waste packaging cardboard are sufficiently resistant to external environmental conditions.</span></em></p>
