BioAmber and Vinmar also broadened the scope of their previously announced 100,000 ton per year 1,4 butanediol (BDO) plant, which the parties currently plan to start up in late 2017. Under that agreement, following the financing, construction and commissioning of the BDO plant, Vinmar has committed to purchase and BioAmber has committed to sell 100% of the BDO produced for 15 years. As part of the new succinic acid master off-take agreement, this second plant will be expanded to an annual capacity of 100,000 tons of bio-BDO and 70,000 tons of bio-succinic acid. Vinmar plans to make a 10% or greater equity investment in the expanded plant and has committed to off-take and BioAmber has committed to sell a minimum of 50,000 tons per year of bio-succinic acid for 15 years following the plant's start-up date. Vinmar also has the option to secure additional bio-succinic acid tonnage under the take-or-pay contract if BioAmber has not committed the remaining volume at the time the plant's financing is secured.
Vinmar also committed to off-take and BioAmber committed to sell a minimum of 150,000 tons per year from a new, third plant following its financing, construction and commissioning. The plant would be dedicated to bio-succinic acid production and would have an annual capacity of 200,000 tons per year. Vinmar plans to invest at least 10 percent of the equity in this third plant, which BioAmber expects to start up in late 2020, based on the projected development of the succinic acid market.
