Florrea METGO Innovative Solutions 
for Cadmium and Arsenic Removal from Phosphoric Acid

As the global population expands, food safety and security concerns prevail. Phosphate-based fertilizers and animal feed often contain heavy metals, such as cadmium and arsenic, which are under scrutiny for their carcinogenic and mutagenic properties, and impacts on aquatic life.
 Today’s fertilizer and feed producers face challenges implementing cost-effective heavy metal removal solutions.

 Florrea's scientists and metalluegists has developed and applied innovative METGO series green chemicals and solutions to help.

Florrea METGO Heavy Metal Removal reagents can efficiently and cost-effectively removes cadmium from phosphoric acid used in fertilizer and feed products. 
Metals typically removed are cadmium and arsenic.

Improve Animal Feed and Fertilizer Purity
Florrea’s METGO solutions are a family of industry-leading heavy metal removal reagents strategically designed to improve the purity of the final animal feed and fertilizer products.

 These specialty reagents increase the efficiency and safety of phosphoric acid production, facilitating effective decadmiation to enable compliance with existing and pending regulatory restrictions. 

Removing Cadmium, Arsenic and Other Metals for Safer Fertilizers and Animal Feed is a great challenge.

Regulations for heavy metal effluent limits are becoming stricter as the industry realizes their potential environmental impact.

A growing global population and higher caloric intake are leading to an increase in demand for phosphate-based fertilizers and animal feeds. Phosphate rock used in the production of these products often contains cadmium (Cd), arsenic (As), and other heavy metal impurities at concentrations that are considered to be toxic and mutagenic to humans. 
Accordingly, existing and pending heavy metal regulations, especially in the EU, limit heavy metal content in finished phosphate fertilizers and feeds, necessitating the removal of impurities. 

Many decadmiation technologies offer high Cd removal rates from phosphoric acid, but few have been implemented due to process inefficiencies or undesirable byproducts; as a result, fertilizer producers have been slow to adopt these technologies at industrial scale.

Used primarily in the filtration stage within phosphoric acid plants, Florrea’s METGO heavy metal removal reagents provide a simple, effective and economical technology for achieving significantly reduced Cd and As levels in phosphoric acid, enabling compliance with current and anticipated regulatory requirements.

Heavy Metal Reduction
METGO reagents can help customers reduce heavy metal concentrations . Also, unlike conventional solutions, Florrea’s METGO 
 introduces the potential to remove heavy metals other than arsenic (As) or cadmium (Cd), such as mercury (Hg) and copper (Cu). 

Efficient & Cost-Conscious
Florrea METGO reagents substantially improve operational efficiency by reducing phosphate loss that normally results from excessive heavy metal concentrations. 
Additionally, because METGO  is a bolt-on technology, it requires minimal capital expenditure and no additional unit processes. 
In terms of dose, METGO can be adjusted based on heavy metal levels in the feed to consistently achieve heavy metal removal targets.

Safety & Sustainability
 METGO reagents generate minimal-to-no H2S, thereby reducing the risk of exposure to hazardous chemicals. For this reason — and its downstream benefits with respect to food safety and ecosystem preservation (e.g., limiting heavy metal runoff into bodies of water) — METGO can play an important role in helping organizations achieve multifaceted sustainability goals.

Supply Chain Flexibility
 METGO use enables plants to be flexible in that they can source ore of varying heavy metal concentrations. 
Compliance and Product Differentiation  
By enabling phosphate producers to develop offerings featuring low heavy metal content, fertilizer and feed producers stand to generate greater value through product differentiation and premium brand positioning. Additionally, with regulations tightening, and efforts such as the EU’s Green Label initiative and the Safe Food/Feed program gaining traction, the agriculture industry continues shifting toward safer fertilizers through Cd removal to limit concerns over food safety and impacts on ecosystems. Our innovative heavy metal removal technology was developed in anticipation of these standards to facilitate compliance with future regulations and help fertilizer and feed producers maintain their license to operate. 

Florrea METGO Heavy Metal Removal reagents offer an efficient method to reduce cadmium and arsenic levels during the processing of phosphoric acid.
