(Universidade Tecnológica Federal do ParanáToledoBrasilTecnologia em Processos QuímicosUTFPR, 2017-06-05)
Conventional plastics are produced from petroleum derivatives, a non-renewable natural resource, in which they present various environmental problems mainly due to their difficult decomposition. Because of their characteristics, ...
Valorization of Spent Coffee Grounds as Precursors for Biopolymers and Composite Production
(2022-02-01)
Spent coffee grounds (SCG) are a current subject in many works since coffee is the second most consumed beverage worldwide; however, coffee generates a high amount of waste (SCG) and can cause environmental problems if not ...
Effects of Extractives on the Surface Chemistry and Wettability of High Temperature Chemithermomechanical Pulps
(2004)
The effect of extractives on surface chemistry and fiber wettability of high temperature chemithermomechanical pulps (HTCTMP) was studied in a model system. Dispersions of abietic acid, oleic acid and a mixture of both ...
