Preparation and Extraction of Pectin from Robusta Coffee (Coffea canephora) Peel Waste as a Sustainable Agriculture Biomass

BIO Web of Conferences, Год журнала: 2025, Номер 165, С. 09001 - 09001

Опубликована: Янв. 1, 2025

Indonesia is one of the top global coffee producers. In 2023, produced high productivity up to 760.2 thousand tons, primarily dominated by robusta ( Coffea canephora ). However, this situation may raise significant environmental concerns regarding disposal peel waste. About 0.18 tons waste estimated be generated per 1 ton processed beans, which needs proper management. Meanwhile, contains a valuable component pectin that can used in various applications support circular economy and sustainability. This study aimed investigate composition characteristics extract from Coffee sample was collected Sambak Village, Magelang Regency, Central Java, Indonesia. The acid extraction method applied obtain using solvent HCl (1 M) alcoholic precipitation with ethanol (96%). 6.23 ± 2.43 % yield on average extracted 100 g dried FTIR test results confirmed presence functional groups at peak points 3320.46; 1731.69; 164.92 cm -1 . These findings showed promising sustainable ways utilize agricultural biomass.

Coffee Silverskin as a Sustainable Alternative Filler for Plywood: Characterization and Performance Analysis

Materials, Год журнала: 2025, Номер 18(7), С. 1525 - 1525

Опубликована: Март 28, 2025

Coffee silverskin, a by-product of coffee processing, was studied using microscopic (SEM), spectroscopic (FTIR), and thermogravimetric (TGA, DSC) methods to assess its use as substitute filler in the manufacturing plywood. TGA showed that material compatible with plywood hot pressing temperatures (140 °C) it thermally stable up 50 °C, notable decomposition event at 335 °C. Functional groups like hydroxyl carbonyl were detected by FTIR analysis, indicating possible hydrogen bonds chemical adaptability. DSC analysis confirmed structural alterations highlighting endothermic processes associated dehydration an exothermic transition over 150 silverskin substituted rye flour adhesive compositions different concentrations (0%, 1%, 5%, 10%, 20%). Due constraints filler, larger (10% 20%) dramatically lowered bonding strength, whereas low amounts (1% 5%) attained strengths equivalent flour, reaching 5 N mm-2, according internal bond strength tests. SEM images revealed smaller, more fragmented, porous particles than larger, compact particles, which affected mechanical interlocking adhesion. The findings point environmentally friendly performance-balancing for conventional fillers, especially medium levels.
