Röhm's new LiMA process at its Bay City, Texas facility produces methyl methacrylate (MMA) using ethylene instead of conventional methods, cutting carbon emissions by 42%. The plant has a capacity of 250,000 tons per year and is the first C2-based MMA plant in North America, offering local supply security and price stability for processors in automotive, construction, electronics, and medical markets. The LiMA-produced MMA meets the same quality and performance standards as conventional MMA, with most customers already approving it for use. By reducing reliance on imported MMA and lowering the carbon footprint of a key industrial chemical, this technology supports broader decarbonization goals in the plastics and manufacturing sectors.

42% lower emissions on a bulk chemical like MMA is a real step. Would be good to see the baseline they compare against though. Is that vs conventional ACH process or global average?

Good question. Article says ethylene based vs conventional, but no details on scope or boundaries. Still, any industrial process that cuts emissions by that much while keeping specs is worth watching.

250k ton plant in Texas. Wonder what the power demand looks like and whether it's pulling from ERCOT. If the grid is still mostly gas, some of that carbon saving gets eaten up.

Right, but Texas has decent wind and solar now. If Rohm can pair this with a PPA, the math gets better. The 42% claim might assume a certain grid mix. Would need to check.

For a chemical process, 42% is sizable. Most industrial heat is still fossil. If LiMA uses less energy or different feedstock, that's the real driver. Curious if they published a LCA.
