Engineers in Australia say they're using spent coffee grounds to make stronger and more sustainable concrete, as producing it accounts for around 7% of the world's greenhouse gas emissions.
It’s also possible to sprinkle used coffee grounds for plants or combine them with water for a liquid fertilizer. Add banana peels or eggshells for even more effectiveness. Eggshell Liquid vs Granular Fertilizer Options Most growers have a preference for liquid or granular fertilizer; this selectio...
A promising technological approach to modifying concrete with plant waste is the introduction of components based on the processing of coffee production waste into concrete. This study aims to investigate the use of biochar additives from spent coffee grounds (biochar spent coffee grounds鈥擝SCG) in ...
Used coffee grounds make good soil amendments. That’s the buzz among gardeners lately. But what do your coffeepot’s leftovers really add to the soil? Sunset Adding Compost To Soil See how to improve your soil for healthier plants and a better harvest. ...
Soxhlet and accelerated solvent extraction, using propanol as a solvent, and supercritical CO2 extraction methods presented statistically insignificant differences in the crude oil yield obtained from spent coffee grounds. Supercritical CO2 extraction method was selected to recover the oil. The optimal ...
Coffee grounds contain 2% of nitrogen, but plants can not use this until it breaks down. As these grounds decompose, the low nitrogen level in them acts as a long-acting fertilizer. Coffee grounds also provide a healthy and slight dose of other basic nutrients like phosphorus and potassium. ...

The pavilion incorporates reusable design into its structure — via the use of organic elements such as orange peel and coffee grounds in the construction materials — and has a natural climate mitigation system that uses shading, misting and ventilation to replace air conditioning. There are no co...
Mn (manganese) exists in various oxidation states in soil, and Mn2+ is the most mobile species of Mn, which is toxic to plants and restricts their growth. When soil is contaminated with trivalent chromium (Cr3+), Mn oxides in the soil are reduced to Mn2+
