Abstract
The use of uni-materials can reduce the total waste generation by a high recycling rate. This study assesses the public's willingness to pay (WTP) a premium for the uni-material beverage container (UBC) in Korea using a specific case of bottled mineral water in polyethylene terephthalate (PET). For this purpose, a contingent valuation (CV) survey of 1000 consumers was conducted to derive the additional WTP for the mineral water in UBC instead of that in non-UBC. Given that the average price of the mineral water (500 mL) in non-UBC was KRW 1000 (USD 0.88), the mean additional WTP a premium for that in UBC was estimated to be KRW 107 (USD 0.09). This value amounts to 10.7% of price of the mineral water in non-UBC and can be interpreted as the public value of the UBC. The consumers in Korea are ready to pay a significant premium for UBCs.
