The decomposition of organic waste going to landfills produces methane gas, which is 21 times worse than CO2 in its global warming potential. Spent coffee grounds (SCG) are one type that makes up a significant proportion the landfills. Therefore, it becomes imperative look for recycling solution transform this into valuable resource. concrete industry has potential contribute significantly increasing rate material. However, due high content, unsuitable be used directly structural concrete. experimental project looks at pyrolysing different temperatures (350 and 500 °C) identify suitability improving physicochemical mechanical properties raw pyrolysed forms SCG were as replacement fine aggregates (FA; sand) 5, 10, 15 20% volume levels. X-ray fluorescence (XRF), Carbon, Hydrogen, Nitrogen, Sulfur (CHNS) analysis, laser diffraction particle size (XRD), scanning electron microscopy (SEM) compressive strength tests undertaken investigate material their performance blended composites. results show leaching compounds from hinders hydration reaction cement particles, thereby hampering SCG-blended 350 °C led improvement properties, resulted 29.3% enhancement composite with biochar.

Current estimates place the amount of spent coffee grounds annually generated worldwide in 6 million ton figure, with sources being classified as domestic (i.e., household), commercial houses, cafeterias and restaurants), industrial soluble instant industries). The majority produced are currently inappropriately destined for landfills or to a form energy recovery (e.g., incineration) refuse-derived fuel. disposal allows its anaerobic degradation consequent generation emission aggressive greenhouse gases such methane CO2, processes must be considered an end-of-life stage lifecycle grounds, way delaying CO2 emissions avoiding toxic organic volatile compounds during combustion this type waste. Aside from these environmental issues, aspect that should is inappropriate product (SCG) presents unique thermo-mechanical properties textural characteristics rich diversity classes compounds, polysaccharides, proteins, phenolics, lipids alkaloids, which could recovered used applications, including food-related ones. Therefore, researchers invested studying variety possible applications products thereof, (but not limited to) biofuels, catalysts, cosmetics, composite materials, feed food ingredients. Hence, aim essay was present comprehensive review recent literature on proposals utilization focus chemical composition coffee, bioactive use ingredients components manufacture materials can packaging.

The widespread adoption of 3D printers exacerbates existing environmental challenges as these machines increase energy consumption, waste output, and the use plastics. Material choice for printing is tightly connected to challenges, such researchers designers are exploring sustainable alternatives. Building on efforts, this work explores using spent coffee grounds a material prototyping with printing. This material, in addition being compostable recyclable, can be easily made printed at home. We describe detail, including process making it from readily available ingredients, its characteristics parameters. then explore how support practices well HCI applications. In reflecting our design process, we discuss opportunities community personal fabrication. conclude set considerations others weigh when materials prototyping.
