Sustainable bioceramics, biopolymers, and composites for bone applications: From bench to production

open access: yesInternational Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract In response to environmental challenges and primary resource scarcity, sustainable approaches that rely on recycling and reusing waste materials are becoming highly valuable and appealing options in modern society. These strategies have started being applied in biomaterials science, too, leading to the advent of new synergies between ...

Biowaste energy potential in Kenya

open access: yesRenewable Energy, 2010
Abstract Energy affects all aspects of national development. Hence the current global energy crisis demands greater attention to new initiatives on alternative energy sources that are renewable, economically feasible and sustainable. The agriculture-dependent developing countries in Africa can mitigate the energy crisis through innovative use of the ...

Sustainable 3D printing of bone scaffolds using animal biowaste feedstocks

open access: yesNext Sustainability
Numerous 3D printing feedstocks are currently being studied for the 3D printing of bone scaffolds for bone regeneration, with differing degrees of success. Most of these feedstocks are produced using ceramics, polymers, and composites.
