Description

The imaginative and sustainable application of a recent development in nanotechnology has lately increased the stability and usability of agricultural food wastes. Another strategy for valorizing consumable food waste is to use it to create functional foods. When the entire production process is considered, there are a lot of agricultural food wastes and byproducts created globally. Agro waste includes crops, plant trash, pesticides, fertilizer, and dairy waste, including dairy leftovers. These wastes and by-products include significant amounts of bioactive chemicals. In order to meet the continually increasing demand for energy-efficient building construction materials, it is imperative to apply affordable, environmentally friendly technologies, upgrade traditional techniques utilizing materials that are readily available locally, and implement these measures. One of the most typical agricultural waste ashes, rice husk ash, is currently being studied to see how engineering disciplines may use it.

In addition to being used as filler in thermoplastics and rubbers, a reinforcing agent, an adsorbent in polymer composites and an epoxy thermo stable polymer for refractory materials, these applications also include wastewater treatment, an additive for the cement industry, alkali-activated materials, as an additive for the production of glass, silicate, pure silica, silicon carbide, and refractory materials. The current study looks at how rice husk ash, one of the most common agricultural waste ashes, is activated and how engineering disciplines can utilize it. Reducing food waste and by-products is the best method to safeguard the environment, the economy, and society.

Despite the fact that many countries have laws in place to reduce food wastes and byproducts and that there are many management approaches available to use agricultural food wastes, they are nevertheless produced on an annual basis. In this overview, these techniques are covered in detail with examples. Another way to valorize consumable food waste is to use it in the creation of functional foods. Agricultural wastes (agro wastes) are often discharged in the environment after being burned as fuel, solid fuel, or for other comparable purposes, which results in environmental issues.

Alumina and silica, two precious elements found in large amounts in these materials that are landfilled, are prospective substitutes for components used in expensive engineering items. Researchers have always been interested in finding the best ways to utilize these wastes, and employing them for a variety of tasks is an effective management tactic. Despite the recent attention paid to agricultural waste ashes by numerous academics in a number of engineering fields, different types of ashes are produced based on preparation conditions and activation techniques. The rapid industrialization and population growth are the main causes of the increased demand for ethanol on a global scale.

Conventional crops like corn and sugarcane cannot meet the global need for bioethanol production due to their primary usage as food and feed. Agricultural waste and other lignocellulose materials are thus suitable feedstocks for the production of bioethanol. Agricultural trash is affordable, plentiful, and regenerative. Using agricultural waste to make bioethanol has the potential to be a successful technology, but there are a number of challenges and limitations with regard to managing and transporting biomass as well as using efficient pretreatment methods for full lignocellulose delignification. Appropriate pretreatment methods can increase the amounts of fermentable sugars after enzymatic scarification, improving the efficiency of the entire process.

Due to the scarcity of natural resources, growing urbanization is leading to a shortage of traditional building construction materials. On the other side, the energy used to produce traditional building materials pollutes the air, water, and land. Another significant difficulty in developing nations is the disposal of solid waste, both agro industrial and otherwise.

Conclusion

The current study investigates the potential use of agricultural waste as a component of sustainable construction materials. As a result, based on the makeup of the finished product, several uses are taken into account. Sustainable building materials are analyzed for their physico-mechanical qualities, production processes, and environmental impact based on the availability of agro-waste resources. The utilization of agro-waste for environmentally friendly building materials offers a solution that saves energy and natural resources.
