Introduction
Renewable materials are compounds obtained from natural resources that can be renewed or regenerated reasonably quickly within a time range that is important to humans.These materials are obtained via renewable or regenerative processes and are commonly utilized in diverse industries because of their environmentally beneficial and sustainable characteristics.The key characteristics of renewable materials encompass sustainability, biodegradability, low environmental impact, reduced dependence on finite resources, diversity in sources, versatility and applications, lifecycle consideration, regenerative processes, and eco-friendly properties.Renewable resources are vital elements of sustainable development and environmentally friendly practices.Their attributes aid in lessening the environmental effect, diminishing reliance on limited resources, and promoting a more sustainable and circular economy.
Green Chemistry is a discipline that concentrates on creating chemical goods and procedures that minimize or eradicate the use and production of dangerous substances.The concepts of Green Chemistry, as established by Paul Anastas and John Warner, prioritize sustainability, efficiency, and environmental responsibility in the domains of chemical research, development, and manufacture.These principles serve as directives for developing chemical processes that are safer, less hazardous, and more sustainable.Preventing waste generation is more preferable than the subsequent cleanup or treatment of garbage.Developing strategies to limit trash generation is crucial; Efficiently synthesize compounds by utilizing all the atoms in the reactants, therefore reducing the production of waste byproducts; Develop synthetic methodologies to utilize and produce compounds that exhibit minimal or negligible toxicity towards human health and the environment; Create compounds with less toxicity while preserving their efficacy in their designated uses; Employ more secure solvents and auxiliary chemicals in chemical operations, while minimizing the utilization of volatile, poisonous, or environmentally detrimental elements; Integrate energy-efficient techniques into chemical processes to minimize energy usage and advance sustainability; Employ renewable raw materials or feedstocks obtained from sustainable sources to reduce dependence on non-renewable resources; Develop methodologies that reduce the utilization of superfluous derivatives, which necessitate supplementary reagents and produce waste; Employ catalytic agents in processes to optimize reaction efficiency, decrease energy demands, and minimize waste generation; Create compounds that undergo complete breakdown into harmless byproducts upon usage to prevent any accumulation in the environment.Furthermore Integrate analytical approaches that enable immediate monitoring and regulation of chemical reactions to reduce the production of dangerous chemicals.
The study primarily examines the utilization of renewable materials in green chemistry, specifically focusing on biomass-sourced renewable materials, as well as other renewable materials such as food waste, recyclable plastics, and paper.This paper provides a thorough examination of the advantages and challenges related to renewable materials in the realm of green chemistry.

Application of renewable materials from biomass sources
The author's objective is to categorize the use of renewable materials in green chemistry into several sections, including biomass-based recyclable materials, the repurposing of biomass waste, the utilization of food waste, the recycling of plastics and paper, and the implementation of renewable energy.2.1.2.Reuse of biomass waste.Biomass waste reuse is transforming organic matter derived from plants, animals, and microbes into valuable commodities or sources of energy, instead of allowing them to be disposed of as waste.These waste items frequently comprise agricultural residues, food waste, wood residues, municipal solid trash, and other similar substances.Below are several techniques for the repurposing of biomass waste.Bioenergy production involves the conversion of waste plant materials, such as wood chips, straw, and maize stalks, into bioenergy sources, which include biomass fuels like pellets and biochar, as well as biodiesel.Biological fermentation is a process that can transform organic waste into valuable biochemicals such as bioethanol, acetic acid, lactic acid, and other compounds that are utilized in various industries and pharmaceutical applications.Anaerobic digestion is a process in which organic materials are broken down without the presence of oxygen to produce biogas [2].This biogas can then be utilized for the creation of power and heating purposes.The resultant digestate can also function as an organic fertilizer.Biodegradable Plastics and Packaging Materials: Biomass waste can be employed to make biodegradable plastics and packaging materials, reducing reliance on regular plastics and lessening environmental impact.Utilizing biomass waste for the production of organic fertilizers enhances soil quality and stimulates crop development, hence fostering soil vitality and ecological equilibrium.Utilization of Biomass Waste for Biomass Chemical Production: Biomass waste can be employed to synthesize bio-based chemicals that find applications in diverse products, such as bio-based cleansers, pharmaceuticals, cosmetics, and more.Utilizing biomass waste helps decrease reliance on limited resources, mitigate environmental degradation, and promote sustainable development.However, the adoption of these reuse methods necessitates examining technological feasibility, economic viability, as well as the environmental and societal implications to ensure sustainability and efficacy [3].

Other renewable material applications
The predominant method of harnessing food waste appears to involve categorizing it as kitchen garbage and employing it as fertilizer.Occasionally, it also entails a degree of ingenuity.In addition, the utilization of trash in a more advanced manner has already been implemented.Kitchen garbage, also known as food waste, mostly consists of carbohydrates, dietary fiber, and animal fat.It constitutes a significant portion of municipal waste.The nutritional value of kitchen trash is utilized by using the lactic acid fermentation broth of kitchen waste as a raw material.A catalyst is employed to prepare and extract lactic acid fat from the lactic acid fermentation broth.Polylactic acid, a biodegradable polymer substance, is produced by directly synthesizing lactic acid fat through melt/solid phase polymerization [2].
Regarding plastic recycling, it is important to understand that plastics are classified using resin identification codes (RICs) ranging from 1 to 7, typically located on the bottom of containers.The most often recycled types of plastics are PET (Polyethylene Terephthalate, #1), HDPE (High-Density Polyethylene, #2), PVC (Polyvinyl Chloride, #3), LDPE (Low-Density Polyethylene, #4), PP (Polypropylene, #5), and PS (Polystyrene, #6).Recyclability of plastics varies depending on the location.Consult the local recycling standards to ascertain the specific categories of plastics that your recycling facility is capable of accepting.Plastics labeled as #1 and #2 are commonly and widely acknowledged as recyclable materials.To prevent contamination, it is advisable to thoroughly clean containers before recycling them, as any food remains present can diminish the quality of the recycled plastic.Besides, it is necessary to minimize plastic usage whenever feasible, and contemplate repurposing plastic containers for storage prior to discarding them.When recycling paper, it is important to categorize it into commonly recyclable types such as newspapers, magazines, cardboard, office paper, and corrugated cardboard boxes for subsequent processing.These can be utilized not just for reproduction, but also for several other purposes.Waste paper fibers have a beneficial coagulation assist effect when used in FeCl3 treatment of water with low turbidity.By enhancing the settling speed of flocs, they can improve the turbidity treatment effect [3].
