Natural fibers are dominating many composite industries due to their unique properties such as reusability, biodegradability, and environmental safety. Tamarind fruit fiber (TFF) stands out among the various fruit fibers and has been discovered in large quantities being discarded from the food processing industries. However, many natural fibers are extracted from their sources, which results in deforestation and environmental degradation. As a result, in today's world, recycling waste into new useful products is the primary concern in any field of engineering. In light of this, the current study used TFF obtained from agro industries and processed into fibers, which were then mixed with an unsaturated polyester matrix to create a natural composite material. Furthermore, by considering process parameters and their levels for conducting experiments, an orthogonal array has been achieved using Taguchi's design approach.

Stainless Steel 304 (SS304) is a nickel–chromium–based alloy that is regularly used in valves, refrigeration components, evaporators, and cryogenic containers due to its greater corrosion resistance, high ductility, and non-magnetic properties, as well as good weldability and formability. Multiple regression analysis was used to establish empirical relationships between process variables. Additionally, the established regression equations are employed to predict and compare experimental data. Due to the increasing demands for high-quality surface finishes and complex geometries, traditional methods are being replaced by non-conventional techniques such as wire EDM. This process, which emerged from the electrical discharge machining concept, mainly involves creating intricate components. WEDM results in a high degree of precision and excellent surface quality. Due to the complexity of WEDM, the processing parameters cannot be selected by using the trial-and-error method.

The corrosive properties of the weldments were evaluated using various mediums, such as nitric acid, ferric chloride, and Oxalic acid.

An oil spill refers to the accidental or deliberate release of petroleum or other petroleum-based products into the environment. These spills can occur on land or in water bodies, such as oceans, rivers, or lakes, and can have devastating impacts on the environment, wildlife, and human health. Oil spills can harm aquatic and terrestrial ecosystems by contaminating water and soil, and by affecting the food chain. They can also cause economic losses, such as the loss of fisheries, tourism, and property values. Cleaning up oil spills can be a difficult and expensive process, and the effectiveness of the response can depend on various factors, such as the type and amount of oil spilled, weather conditions, and proximity to sensitive ecosystems. Preventing oil spills is critical to minimizing their impacts.
