Abstract
Aloe vera plant is known worldwide for its medicinal properties and application in gel-based products such as
shampoo, soap, and sunscreen. However, the demand for these gel-based products has led to a surplus production
of
Aloe vera processing waste. An
Aloe vera gel processing facility could generate up to 4000 kg of
Aloe vera waste
per month. Currently the
Aloe vera waste is being disposed to the landfill or used as fertilizer. A sustainable management system for the
Aloe vera processing waste should be considered, due to the negative societal and environmental impacts of the currents waste disposal methods. Therefore, this review focuses on various approaches
that can be used to valorize
Aloe vera waste into value-added products, such as animal and aquaculture feeds,
biosorbents, biofuel and natural polymers. Researchers have reported
Aloe vera waste for environmental applications biosorbents used for wastewater treatment of various pollutants. Several studies have also reported on the
valorization of
Aloe vera waste for production of biofuels such as bioethanol, mixed alcohol fuels, biogas and syngas.
Aloe vera waste could also be valorized through isolation and synthesis of natural polymers for application in
wound dressing, tissue engineering and drug delivery systems.
Aloe vera waste valorization was also reviewed
through extraction of value-added bioactive compounds such as aloe-emodin, aloin and aloeresin. These
value-added bioactive compounds have various applications in the cosmetics (non-steroidal anti-inflammatory,
tyrosinase inhibitors) and pharmaceutical (anticancer agent and COVID 19 inhibitors) industry.
