Single-use plastic pouches are still the default packaging choice for Indonesian food SMEs that sell oily products suchas fried snacks, traditional chips, and pastries, even thoughthis kind of packaging is difficult to recycle once it has beenin contact with oil and keeps adding to the plastic wasteproblem. Meanwhile, two waste streams in West Java are rarely put to use: oncom dregs left over from the soybean and peanut fermentation industry, and ramie fabric scraps from Majalaya's small-scale weaving businesses. This business ideacombines both waste streams into a single oil-barrier bio-packaging pouch instead of processing them separately. The oncom dregs are formed into a protein-based film, reinforcedwith shredded ramie fiber, and finished with a natural waxcoating so the pouch can resist oil and grease in a waycomparable to conventional plastic. Production follows a solution-casting method using glycerol as plasticizer, CMC/chitosan as binder, and citric acid as a natural preservative, with tensile strength, oil resistance, and biodegradation rate as the main properties to be tested. A techno-economic feasibility study was also carried out, covering CapEx, monthly OPEX, break-even point, and a twelve-month cash-flow projection; the cost estimate has beenexpanded to include not only production equipment but alsobusiness licensing, product testing, branding, and an initialworking-capital buffer. At a pilot capacity of 1,000 pouchesper month, the cost of goods manufactured comes to IDR 5,369 per unit against a proposed selling price of IDR 12,000, giving a gross margin of 55.3% and a break-even point of around 386 units per month, or 38.6% of capacity. By targeting oil-based food SMEs as the primary market, this dual-waste approach offers a scalable alternative to conventional plastic packaging that is rooted in the local economy, supporting SDG 8, 9, and 12.
