A pool construction using ramie fabric composite in eco-resin matrix: a cost of goods sold analysis (COGS)

Abstract

One of the oldest and most traditional products made with resin and fiberglass is swimming pools; however, this product consumes large quantities of fiberglass mat and resin, both raw materials are based on non-renewable products and contribute significantly to carbon footprint and environmental damage. The increasing environmental concern has raised awareness in the industry and academia for the search of environmentally friendly materials. Natural fibers are attracting interest in engineering sectors due to specific advantages such as low density and cost, as well as renewability, biodegradability, recycling, and CO2 emission neutrality. In particular, the fiber extracted from the stem of the ramie plant is currently recognized as one of the strongest lignocellulosic fibers. In addition to natural fibers, eco-resins such as water-based acrylics have gained great attention from the industry due to their carbon footprint and environmentally friendly characteristics. The aim of this work is to calculate the cost of goods sold (COGS) for a pool constructed with composite ramie fabric in a water-based eco-resin matrix, for this purpose, a 1:30 scale prototype will be made, from which all manufacturing costs will be collected, then we will perform a mathematical extrapolation for comparison of values with products currently available in the market.
