The need for plastic solutions has increased as a result of the expansion in the usage of plastic-based items, adding pressure to the waste management system. The use of plastics derived from petroleum, which significantly harm the environment, is being reduced with great interest. Substituting biodegradable plastic made from natural resources such as unprocessed agricultural waste, aquatic life, and even microbes for traditional plastics made through the petrochemical process is one way to address the problems. The worldwide bioplastics and biopolymer targets are the focus of all these initiatives. The focus of this study is on the sea grape, or Caulerpa lentillifera. The Caulerpa lentillifera plant, which is widely distributed along Sabah's east coast and in the Malacca Strait and is significant economically in Malaysia, was also mentioned. It possesses antibacterial qualities and is found in abundance there. The goal of the innovation project is to create biodegradable plastic from Caulerpa lentillifera and test the anti-microbial capabilities of the plastic. It is anticipated that this novel product will benefit society and have a high likelihood of being commercialized. Due to its remarkable biodegradability, the use of biodegradable plastic has recently become more popular. It is very simple to stretch and can lessen the environmental impact because it does not release carbon dioxide. Additionally, it does not produce a lot of hazardous emissions and has the potential to biodegrade into a natural component that blends into the soil. Additionally, biodegradable packaging has found use in several industries such as consumer goods and medical technology. The Sustainable Development Goals (SDGs) established by the United Nations, particularly SDG 14 which focuses on the conservation and sustainable use of marine resources, are also in line with this unique idea.
