Houston companies partner on sustainable plastics alternative
Two Houston companies, Lummus Technology and Citroniq Chemicals, have paired up to build North American plants that produce green polypropylene.
Polypropylene is a thermoplastic used to manufacture items such as plastic packaging, plastic parts, medical supplies, textiles, and fibers. Green polypropylene is made from biomass.
Lummus and Citroniq say their first plant, set for completion in 2027, will produce 400,000 metric tons of green polypropylene each year. The plant will be at an undisclosed location in the Midwest.
In April, Lummus and Citroniq signed a letter of intent to develop Citroniq green polypropylene projects in North America using Lummus’ Verdenesuite of polypropylene technology. Their newly announced licensing and engineering agreements apply to the first of four planned facilities.
“This agreement demonstrates the progress we continue to make with Citroniq in establishing the first world-scale sustainable bio-polypropylene production process in North America,” Romain Lemoine, chief business officer for polymers and petrochemicals at Lummus, says in a news release.
“Combining Lummus’ leadership in polypropylene licensing with Citroniq’s carbon-negative production capabilities will help us meet the growing demand for bio-polypropylene and accelerate the decarbonization of the downstream energy industry,” Lemoine adds.
Citroniq says it’s investing more than $5 billion to expand its E2O process. The process produces carbon-negative plastics and hydrogen-and-carbon compounds called olefins from fully sustainable feedstocks. This eliminates the use of convention fossil-fuel hydrocarbons, Citroniq says.
Mel Badheka, principal and co-founder of Citroniq, says his company aims “to meet the market’s growing need for sustainable carbon-negative polypropylene at a competitive price.”
The global market for green polypropylene was valued at $123.5 billion in 2022, according to Grand View Research. Growth in the sector is being driven in part by the construction industry, the firm says.
