Anaerobic digestion of spent coffee grounds

Biomass, 1983
Anaerobic digestion of spent coffee grounds (3 kg m−3 day−1) with efficient solids recycling achieved 99% conversion of solids and gas yields of 0·54 m3 kg−1 (56–63% methane). Gas production declined steadily over the test period and after 80 days had fallen from an initial value of 1·70 litre litre−1 day−1 to 0·45 or 0·33 litre litre−1 day−1, with or ...

Spent Coffee Grounds for Energy Generation

2022
Em face da necessidade do desenvolvimento de novas tecnologias para geração de energia, têm surgido propostas que visam a adoção de biomassas alternativas para tal finalidade. No presente trabalho, é proposta a utilização da borra de café, um rejeito urbano doméstico geralmente descartado, para produção de biocombustíveis e geração de energia. Uma rota

Study of Valorisation Routes of Spent Coffee Grounds

Waste and Biomass Valorization, 2020
The energy crisis is an eminent problem that needs to be dealt with urgently. Thus, alternative routes for the production of biofuels are sought. This paper investigated experimentally the possibility of biodiesel and bioethanol production from spent coffee grounds (SCG), aiming at the same time to manage an emerging waste stream.

Green nanocomposites filled with spent coffee grounds

Journal of Applied Polymer Science, 2015
ABSTRACTThis study evaluated physical properties of the nanocomposites reinforced by used coffee grounds. Coffee grounds were ball‐milled and filtered in an effort to secure nanoparticles for the fabrication of polyvinyl alcohol (PVA)/coffee nanocomposites.
