2. Overview + Updates
● Chemicals that companies no longer want to retain in their inventory but still have strong
potential for reuse.
● Sodium Sulfate Anhydrous - Primary Exporters are in China (Jiang Xi Albemarle Lithium
Co. and Guangdong Guanghua Sci Tech Co ltd were contacted).
● Spent Sulfuric Acid - Primary exporters are in India (Laxmi Agro Industrial Consultants &
Exporters and Eastern Petroleum were contacted).
4. Product Overview - Ferrous Sulfate Heptahydrate
● Most common hydrate of ferrous sulfate.
Characterized by its vivid green colour.
● Byproduct of the TiO2 manufacturing process.
● Used in several industries including the textile
industry, healthcare and pharmaceutical
industry and is placed on the WHO’s ‘List of
Essential Medicines.
● Top exporters of ferrous sulphate
heptahydrate (based on quantity) are Sri Lanka
(~21.2%), Pakistan, Bangladesh and Kenya.
5. Product Overview - Recycled Solvents
● Solvents are widely used in a variety of industrial
applications.
● There are three main types of solvents:
○ Oxygenated Solvents
○ Hydrocarbon Solvents
○ Halogenated Solvents
● Applications in manufacture of many products such as
cosmetics, sealants, pharmaceuticals, adhesives,
paints and coatings, printing inks and many more.
6. Product Overview - Recycled Solvents
● The spent solvent from industrial processes are diluted and may contain some
impurities
● Hence, often most solvents can be refined and reused, termed recycled solvents
8. Market trends & Data
01 - Ferrous Sulfate Heptahydrate
- Greatest Quantity of Exports are from Sri Lanka, Pakistan
and Kenya.
- For the US markets, the single greatest exporter is the
Dominican Republic.
Client Implications:
- To facilitate trade in Asia and to capitalize on lower export
costs, suppliers in China will also be contacted since the
volumes of export are comparable.

02 - Recycled Solvents
● Of the many solvents used for industrial purposes, the most useful were identified and targeted
due to their extensive supply and large anticipated demand.
● The search was focused on, but not limited to, the following solvents:
○ Toluene
○ Xylene
○ Isopropyl Alcohol
○ Isobutyl Alcohol
○ Ethyl Acetate
○ Acetone
○ Methylene Dichloride (MDC)
11. Key Take-aways
● The sources of ferrous sulfate heptahydrate are scattered across the globe so we will have to take into account both
cost of shipping and the price per MT of the product being shipped.
● The main sources of recycled solvents are specialised companies that collect, refine and resell waste solvents. Sourcing
waste solvents can be looked into by identifying industries that use a specific solvent in their manufacturing process,
and checking with them for their waste solvent.
● Sourcing surplus chemicals is proving to be challenging because we don’t know which surplus chemicals are listed by the
companies. Most companies tend not to list the B-grade or excess chemicals, so moving forward, we will be splitting the
product wise sourcing and the sourcing of all surplus chemicals.
Oxygenated Solvents:
Contain oxygen in their molecular structures
Includes alcohols, ehers, esters, glycol ethers, glycol ether esters and ketones
Hydrocarbon Solvents:
Chemicals structures contain hydrogen and carbon atoms with complex chemical structures
Aliphatic: gasoline, kerosene and hexane
Aromatic: Benzene, xylene and toluene
Halogenated Solvents:
Contain halogen atoms (fluorine, bromine, iodine or chlorine) in their molecular structure
Examples include perchloroethylene, chlorinated fluorocarbons, and 1,1,1-trichloroethane
