Human uses of algae-derived products
Algae are plant-like organisms that mainly grow in aquatic environments and have no typical
plant features such as roots, leaves, stem and vascular tissue. Algae also typically do not flower.
There are many types of algae, and some of them are poisonous while others are utilized for
various human uses. This essay will discuss the different products derived from algae and their
i) Biofuels and associated products
Algae are used to make biofuels (which can be used as cooking and industrial gas), bio-oils (for
use as asubstitute for petroleum oils uses such as skincare, car surface care, stretch marks care et
cetera), biodiesel (which is used for powering diesel-run engines, heating oil, fuel filters et
cetera), bio-hydrogen (used in electricity production and transportation), bio-methane (used in
electricity production, heating purposes and as automobile production), and bioethanol (used as
motor vehicle fuel, additive in gasoline et cetera) (Mathimani, 2019) .
ii) Additives
Seaweed (a type of micro-algae) is the source of several additives such as carrageenan and algin,
which have various uses in the food industry, primarily as food thickeners, in food products such
as baby formula, yoghurt, ice cream et cetera.
iii) Abrasives
Diatoms are atype of algae which have glass-like shells. These shells have amicro-abrasive
characteristic, making them an ideal candidate for making various products that function as a
result of abrasiveness. These include bathtub cleaners, filtering systems, organic pest control,
toothpaste, et cetera.
iv) Beauty and skincare
Many skin care and beauty products contain algae included in the products because of their
thickening, antioxidant, mineral replenishing, and moisturizing qualities. This makes algae an
ideal ingredient in cosmetic products such as anti-ageing creams, detoxifying masks, cleansers,
et cetera.
v) Nutritional ingredients and supplements
Algae contain omega-3 fatty acids (found in Fish that get itby eating algae). Most companies
producing omega-3 fatty acids extract the product directly from algae (which have higher
omega-3 fatty acids) to capture vegetarian customers who do not consume Fish. Omega-3 fatty
acids help reduce blood pressure, reduce incidents of abnormal heart rhythm, strengthen arteries,
reduce incidents of heart attack and stroke, et cetera (Barkia, 2019) .
vi) Fertilizer
Algae contain minerals and nutrients which support the fixation of nitrogen and solubilization of
phosphate in plants. The result is healthy plants and higher yields. Since algae-based fertilizers
are organically made, many farmers who do not want to use chemical-based fertilizers opt for
their use, leading to their gradual popularity.
vii) Animal feeds
Kelps, also known as brown algae, are used as animal feeds in many parts of the world. Farmers
harvest itand use itas fodder for cattle, chop itand provide itto sheep and chickens. Other
farmers grow/harvest algae to feed their horses, dogs, cats, aquarium fish and other pets or
domestic animals. Algae types such as spirulina and chlorella are added to whole feeds, foods,
treats and supplements for pets.
Farmers and pet owners prefer to feed their animals/pets algae because itcontains high-quality
nutrients such as proteins, antioxidants, fibre, fatty acids, vitamins, minerals, et cetera. The
minerals derived from algae are considered high quality and contain no toxic elements such as
viii) Aquaculture
Different types of algae are used for feeding Fish by both small and large-scale fish farmers. In
their natural habitat, Fish consume large amounts of various kinds of algae, which is one of the
sources of high-quality nutrients for fishes. Farmers can feed their Fish on different types of
algae according to their growth stage. The small fish lets can be provided with microalgae such
as phytoplankton, while the larger ones can be fed on more significant algae types such as
seaweeds. With alarge variety to choose from, fish farmers can select the type of algae to
provide their Fish according to nutritional needs and availability of the algae (Koyande, 2019) .
Algae are agroup of plant-like organisms which grow abundantly and can be utilized for various
uses by humans. Some algae use biofuels, bio-oils, other organically produced oil products,
animal feeds, food supplements and additives, nutritional ingredients, aquaculture, abrasives for
cleaning and filtering systems, organic fertilizers and many other uses.
Many people prefer algae because they contain high-quality nutrients, do not contain metal
residue such as lead, are easy to obtain and grow, and have minimal side effects.
