That information you posted regarding re-use of heat. It is generally called heat recovery, heat integration  or ecconomization. Generally this is done after a plant is built, but in these energy consious times, it becomes part of the initial design. The estimates of energy savings are comparable and very realistic.

To me, they are moving like a professional management team with an eye on efficiency and operating costs. Future initiatives will include optimization and de-bottlenecking where the throughput of the process can be increased with small capital input. It would not surprise me, at all, for them to produce 20% more than their current nameplate.
