RECYCLING SPENT COFFEE WASTE FOR INNOVATIVE THERMO-PLASTERS: DEVELOPMENT OF A PROTOTYPE
2022
This paper presents an experimental study aimed at testing the real energy performance of a thermo-plaster prototype made of an ordinary mortar boosted by various percentages of spent coffee ground. That is one of the wastes of the brewing process that are usually disposed of in landfill with great concerns for the possible environmental footprint due to its organic nature and possible harmful components. In this paper, the mortar was manufactured froman ordinary Portland cement and sand, partially substituted by the waste. Specimens characterization is briefly outlined and a careful examination of the thermal properties is carried out. A plastering prototype was manufactured and placed in …
Novel green bio-composite geopolymeric thermo-plasters for innovative building applications: upcycling spent coffee ground
2022
This study proposes the reuse of spent coffee ground and biomass fly ash in the development of green geopolymeric thermo-plastering for innovative building applications. The former waste is the major residue of the brewing process, that is usually used as fertilisers or disposed of in landfill with extreme harmfulness for the natural environment. The latter is an industrial waste generated during the Kraft paper-pulp process, that is usually landfilled. The mortar is produced with a combination of metakaolin (30 wt.%) and biomass fly ash (70 wt.%), and natural siliceous sand filled with spent coffee ground (up to 17.5 wt.%). The high amount of reused waste makes the material an optimum cand…
Architectural technologies for life environment: Spent coffee ground reuse in lime-based mortars. A preliminary assessment for innovative green therm…
2022
Spent coffee ground, the residue obtained from the brewing process, is the primary unavoidable (inedible) waste from the coffee consumption. As coffee production and beverage consumption are increasing worldwide, a more sustainable waste management is required since the usual disposal in landfill is a liability to both humans and the environment. This paper is aimed at showing a possible alternative reuse of coffee ground wastes in novel green building materials intended for thermo-plastering applications in construction, in a circular economy context. Coffee waste was used in various percentages (up to 17.5%) to assess the engineering performance of the produced bio-composite mortars. The …
The coffee-house: Upcycling spent coffee grounds for the production of green geopolymeric architectural energy-saving products
2023
This study investigates a possible alternative reuse of spent coffee grounds (SCG), the major residue of the brewing process, to manufacture green geopolymeric materials for innovative building applications in energy-saving construction, in line with the European Green Deal towards zero-energy building. Specimens were prepared by a combination of biomass fly ash from the Kraft paper-pulp process, as raw material (70 wt%), and SCG (up to 17.5 %), as filler. The high amount of reused bio-wastes makes the material fit the requirements for the Minimum Environmental Criteria (MEC) certification, in light of the Circular Economy (CE) approach. Sustainability is also boosted by the manufacturing p…
