WISCONSIN — Lawmakers from northern and north-central Wisconsin are circulating a bill supporting Johnson Timber Corp. in Hayward to build a processing plant for aviation fuel made from logging debris to establish a processing plant in Wisconsin. The legislation would reward the company with a $60 million tax credit and access to $150 million in borrowing through Wisconsin’s bonding authority. Republican lawmakers wrote in a memo circulated Monday seeking cosponsors that the proposal would create 150 jobs and generate $1.2 billion a year in income after three years of operation. The processing plant in Hayward would be built by Johnson Timber Corp., in partnership with a German company… Synthec Fuels. Wisconsin along with Michigan and Minnesota are all vying for the project, Felzkowski said, “and the state that helps will be the first state” to get the facility and probably the headquarters for the overall processing operation.
