“…The circular economy approach, where waste materials are transformed into valuable products, minimizes waste and conserves resources, is highlighted. This aligns with the principles of sustainable and eco-friendly practices (Martini and Sharmeen Afroze, [15]). Aloe vera leaves contain valuable organic materials that, when converted into activated carbon, offer a sustainable and efficient means of resource utilization.…”

Industrial activities such as textile, mining, pharmaceutical, agricultural chemicals, battery production and electroplating, have severely led to ecological pollution in recent years without much mitigating measures. This study aimed to provide valuable insights into sustainable water treatment by examining the synthesis process, characterizing the resulting activated carbon, and evaluating its adsorption efficiency. The main objective was to produce activated carbon from waste Aloe vera leaves for application as an adsorbent in wastewater treatment. The process involved cleaning, drying, carbonization, and activation of the dried Aloe leaves and the resultant activated carbon characterized and tested for its adsorption capacity using methylene blue dye. Consequently, the adsorption capacity analysis and kinetic study explored the adsorption rate over time. Results from the carbonization and activation process showed that, timing influences material adsorption properties while the conversion efficiency at 19.39% and 39.05% indicates the pyrolysis phase was very effective in the conversion of Aloe vera waste to activated carbon. Additionally, adsorption coefficient at 17.1, 10.2 and 24.9 mg/g is consistent with results of kinetic study that showed complete uptake of methylene blue for duration of 2 hours. Effects of pH to the sorption phase was also done and adsorbent established to be at pH of 11.3. The study showed the potential of activated carbon from Aloe vera leaves and its applicability as an adsorbent in wastewater treatment. It is recommended that future research refine the activation conditions further, investigate diverse biomass precursors, and make a thorough economic assessment for large-scale replication through manufacturing.

“…For metal ions, it then connects to the complexation process by forming a complex with the active groups in the cell wall on the cell surface of the adsorbents. The bond formation could be covalent or electrostatic, while the compounds may be neutral, negatively or positively charged [68]. Apart from the aforementioned reactions, the following prominent factors have been suggested as significantly influential points for adsorption processes.…”

The presence of heavy metals in water bodies is linked to the increasing number of industries and populations. This has serious consequences for the quality of human health and the environment. In accordance with this issue, water and wastewater treatment technologies including ion exchange, chemical extraction, and hydrolysis should be conducted as a first water purification stage. However, the sequestration of these toxic substances tends to be expensive, especially for large scale treatment methods that require tedious control and have limited efficiency. Therefore, adsorption methods using adsorbents derived from biomass represent a promising alternative due to their great efficiency and abundance. Algal and seaweed biomass has appeared as a sustainable solution for environmentally friendly adsorbent production. This review further discusses recent developments in the use of algal and seaweed biomass as potential sorbent for heavy metal bioremediation. In addition, relevant aspects like metal toxicity, adsorption mechanism, and parameters affecting the completion of adsorption process are also highlighted. Overall, the critical conclusion drawn is that algae and seaweed biomass can be used to sustainably eliminate heavy metals from wastewater.

“…Without proper attention and management, biomass waste can lead to environmental problems related to water and air pollution, soil contamination, etc. [1]. While some agricultural wastes can be unique in certain areas, their massive untreated waste is detrimental to the sustainable development of the environment and human health.…”

The increasing interest in environmental sustainability and its economic aspects has triggered scientific investigations on biomass’s potential as a new alternative source. Various fields like wastewater treatment, energy, construction material, and fertilizer are connected to biomaterial utilization. This review article discusses current literature related to the implementation of unused and low-cost biomass as either primary or supporting materials that could result in new products with higher economic value. Biomass consisting of plant parts such as rubber seed, eucalyptus bark, rice husks, fruit peels, or animal remnants like animal bones have been effective and potential for further processing. Furthermore, literature has shown that final products supported by or derived from processed biomass materials have potential competitiveness with other typical products entirely made from conventional sources like adsorbents, biofuel, concrete additives, and biofertilizers. After a comprehensive critical review of the relevant present literature, a concise summary can be drawn that biomass waste has reliability and potential function as an alternative resource to obtain low-cost materials for useful products making, and to overcome environmental damages due to increasing organic waste disposal.
