Re: what are some uses (products) for algae?

Try looking in encyclopedias and textbooks on botany, economic botany and 
algae. A librarian can assist you. On the internet, search for algae uses on a 
variety of search engines and you should find a lot of info. Three major 
substances from algae are agar, alginates, and carrageenan. Each is used in 
numerous products. Algae are also used in natural herbal remedies or 
nutritional supplements, in medicine, as food for humans and animals, and as 
fertilizers.
