Saroengrong Wong-Savun is an architect who is interested in environment- friendly design. After graduating from Dallas Baptist University, he started working as an architect in Dallas, Texas, for 2 years and later moved back to his hometown Chiang Mai, in the North of Thailand. He founded a studio called Re-Leaf Studio, which focuses on using waste from nature and daily life as a basis for creativity. The studio has developed a variety of products out of paper, from banana pulp and fiber. In 2010, Saroengrong started his new design studio called Rubber Killer. The philosophy is to look for abandoned materials with tremendous hidden value, like trucks’ inner tubes. Rubber Killer uses used inner tubes to develop new products such as messenger bags, tote bags, backpacks, clutch bags, wallets, notebook covers, cardholders, key rings, etc. He comes up with good design from trash because he believes that recycled materials can be used as creatively as new materials if designers understand and know how to work with them. His designs are very simple but pay great attention to details and proportion. In 8 years, Rubber Killer has recycled more than 30,000 inner tubes to produce bags and other products. Today, Rubber Killer is available in Thailand, Japan, Singapore, Taiwan, Shanghai, France, Germany, U.K. and U.S.A. He also has his organic farm in Chiang Mai, where he grows banana, coffee, fern vegetables, strawberry and rice. Saroengrong has a Bachelor of Architecture from Chiang Mai University and a Master in Marketing from Dallas Baptist University.
