What Chlorum Solutions does

Chlorum Solutions is a privately held industrial company founded in 2014 and headquartered in Chicago that builds, owns, and operates small-scale modular chlor-alkali plants on-site or adjacent to customer facilities in Brazil, Uruguay, and the United States. The company produces chlorine, sodium hypochlorite, hydrochloric acid, and caustic soda using membrane electrolysis technology, eliminating the toxic effluents of legacy mercury-cell production being phased out under the Minamata Convention. Individual plants operate at 10-45 tonnes/day capacities - orders of magnitude smaller than conventional megaplants - and deliver chlorine to customers as highly chlorinated water via pipeline, removing the safety, regulatory, and cost burdens of liquefied chlorine gas transportation, compression, and storage. As of 2026, Chlorum operates or is developing approximately eleven plants across Latin America and the US, including a recently acquired Eddyville, Iowa facility from Cargill, a $70M+ greenfield in Casa Grande, Arizona, and an Igarassu complex under Cape Participação management.

The business model is a multi-year Build-Own-Operate (BOO) arrangement: Chlorum funds 100% of capex, implementation, and operations, and customers pay for products (chlorine and derivatives) over the contract life without making any capital outlay. This structure targets industrial manufacturers and water-treatment utilities in secondary markets far from large petrochemical hubs, which face high logistics costs, supply-chain reliability risks, and safety liabilities when sourcing chlorine. Go-to-market is enterprise field sales with bespoke site or near-site BOO contracts. A parallel chemical distribution warehouse in Suzano (SP), near Porto de Santos, serves mid-market Brazilian customers across paints, metallurgy, steel, water treatment, laundries, leather, and petroleum.

Chlorum is controlled by Klaff Realty LP, with majority shareholder Hersch Klaff backing a R$110 million capital infusion in December 2020 that funded a five-year, seven-plant Latin American expansion plan. The company achieved carbon-neutral status in 2020 and pairs conventional industrial manufacturing with sustainability positioning: a 24 MW renewable-energy supply agreement with Atlas Renewable Energy (April 2025), a Palmeira (SC) plant designed for 100% renewable energy, and a R$290M Igarassu modernization replacing mercury cells with membrane technology. Headcount is reported at 11-50 despite the multi-country asset footprint, implying a lean operator model with revenues concentrated in BOO product sales and a centralized technology and engineering platform.

Revenue model

1. BOO Contract Revenue: Chlorum builds, owns, and operates chlor-alkali plants under long-term Build-Own-Operate (BOO) contracts. Customers receive chlorine products without capital investment, paying for the product over the contract term. The model eliminates transportation costs for customers and provides revenue through recurring product sales over multi-year periods.

Core offering

Chlorum Solutions builds, owns, and operates small-scale modular chlor-alkali plants (10-45 tonnes/day of chlorine capacity) using membrane electrolysis technology under long-term Build-Own-Operate (BOO) contracts. The company locates plants on-site or near customers, producing and delivering chlorine, sodium hypochlorite, hydrochloric acid, and caustic soda "just-in-time" as highly chlorinated water via pipeline, eliminating the need to transport liquefied chlorine gas.

Product overview

Chlorum Solutions is a carbon-neutral company that builds, owns, and operates small-scale modular chlor-alkali plants through long-term Build-Own-Operate (BOO) partnerships. The company offers two main solution lines: Chlorum Industry Solutions for industrial customers and Chlorum Water Solutions for water treatment facilities. Core products include chlorine, sodium hypochlorite, hydrochloric acid, and caustic soda, all produced using membrane technology with zero toxic effluents. Plants are located onsite or near customers, delivering products just-in-time as highly chlorinated water via pipeline, eliminating transportation of liquefied chlorine gas. The company operates across Latin America (Brazil, Uruguay) and the United States.

Scale indicators9 records

Recent moves11 records

Expansion highlights6 records

Direct peers

• Unipar Carbocloro: Largest chlor-alkali producer in Brazil and a direct competitor in the same geography. Produces chlorine, caustic soda, and derivatives using similar membrane technology, making it the most directly comparable peer for Chlorum's Brazilian operations.

Broad incumbents

• Olin Corporation: Largest North American chlor-alkali producer and global leader in chlorine and caustic soda. Provides the benchmark scale and cost structure that Chlorum must differentiate against in the US market via its proximity-based BOO model.
• Westlake Corporation: Vertically integrated chlor-alkali and PVC producer with significant North American capacity. Represents the integrated commodity incumbent Chlorum competes against for industrial chlorine and caustic soda demand.
• Occidental Petroleum (OxyChem): Major US chlor-alkali and PVC producer through its OxyChem subsidiary. Closely comparable product portfolio (chlorine, caustic soda, hydrochloric acid) and serves the same industrial and water treatment customers Chlorum targets in the Midwest.
• Orbia Advance Corporation: Mexican chemical company with significant chlor-alkali and vinyls operations across Latin America. Comparable product mix and regional footprint, particularly relevant as Chlorum expands its Latin American plant network.
• Formosa Plastics Corporation: Vertically integrated PVC and chlor-alkali producer with global operations. Competes for industrial chlorine demand and represents the kind of large-scale commodity player that benefits from economies of scale absent in Chlorum's modular model.
• INEOS Inovyn: European chlor-alkali and vinyls leader owned by INEOS. Operates large integrated chlor-alkali complexes and is a global benchmark for membrane technology deployment, directly relevant to Chlorum's technological positioning.

Regional players

• Braskem: Largest petrochemical producer in the Americas, headquartered in Brazil. While primarily focused on polyolefins, Braskem is a major Brazilian industrial chemicals player and a potential competitor for industrial-scale chlorine, hydrogen, and caustic soda customers.
• Ciner Group: Turkish conglomerate with chlor-alkali and soda ash operations. Operates regional commodity chlor-alkali assets comparable in scale to Chlorum's mid-sized plants and relevant as a model for emerging-market chlor-alkali competition.

Emerging players

• Vynova: European chlor-alkali and PVC producer owned by ICIG. Smaller and more regionally focused than Olin or Westlake, Vynova is comparable in scale and serves as a reference point for mid-tier chlor-alkali economics in developed markets.
