Bending Strength Measurement of Composite Based on Used Coffee Ground and Coffee Husk

Jurnal Otomasi Kontrol dan Instrumentasi, 2023
Meningkatnya konsumsi kopi di Indonesia berakibat pada peningkatan limbah sekam dan ampas kopi yang mengandung tanin, alkaloid, dan polifenol. Limbah tersebut seringkali dibuang begitu saja sehingga mencemari lingkungan. Penelitian ini bertujuan untuk mengolah limbah kopi menjadi material komposit yang dapat dimanfaatkan sebagai bahan pembuatan suatu ...

Solvent‐Driven Pore Engineering in Coffee‐Derived Activated Hydrochar: Implications for Post‐Combustion CO2 Capture

Carbon Energy, EarlyView.
Solvent washing of coffee‐ground hydrochars produces activated carbons with tunable pore sizes while maintaining surface area. Removing non‐polar contaminants enhances microporosity, increasing CO2 uptake by 40%. Moderate pore sizes (9–12 Å) yield optimal CO2:N2 selectivity, whereas smaller pores reduce selectivity due to stronger interactions between ...

Fresh coffee husks as potential sources of anthocyanins

LWT - Food Science and Technology, 2007
Fresh coffee husks, comprised of outer skin and pulp, were investigated as potential sources of anthocyanins for applications as natural food colorants. The extracted pigments were analysed by HPLC with photodiode array detection. Partial hydrolysis and analysis of the resulting fragments were helpful in the characterization procedure.

Integrated and closed‐loop biorefinery strategies for efficient waste valorization and biofuel production

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Advancements in biofuel production technologies are essential for reducing global dependence on fossil fuels and addressing their overexploitation. Many valuable components of biomass, such as cellulose, hemicellulose, and lignin, remain underused in traditional biorefineries, which typically rely on a single feedstock to produce a primary ...
