“…In terms of fertiliser components such as N, P, and S, the most beneficial was the mixture of spent coffee grounds with duck eggshells, also collected on date I (SCG-DES I). The use of fresh spent coffee grounds can be toxic to plants 42 , therefore, it is proposed to compost them or treat them using another method 43 . This study showed that mixing spent coffee grounds with chicken and duck eggshells and incubating them for 3 months can give an organic-calcium fertiliser valuable to plants 39 , 44 , and such a mixture can also be a good soil improver.…”

Spent coffee grounds (SCG) as well as chicken (CES) or duck eggshells (DES) left over from the artificial hatching technology are proposed as potential soil improver and/or organic-mineral fertiliser components. Therefore, it seems interesting and necessary to evaluate the chemical composition of these wastes and their mixtures in terms of their possible use for that purpose. The study was conducted under the incubation experiment conditions using a mixture of SCG and eggshells (10:1 ratio). Macronutrients, i.e. C, N, S, were determined by the catalytic combustion method, while P, K, Mg, Ca, Na by atomic spectrometry. It was found that SCG were rich in C, N, P, and K, while eggshells in Ca, Mg, Na, and S. However, CES compared to DES were richer in deacidifying components (i.e. Ca, Mg, K). At the same time, the content of macronutrients in eggshells decreased gradually along with the embryo development. For this reason, the mixture of SCG and shells of unembryonated chicken eggs (CES I) had the best chemical and usable proprieties. To conclude, the chemical properties of the mixtures of spent coffee grounds and eggshells indicate their possible application in soil bioengineering.

“…Along with other phenolic compounds such as tannic acid, chlorogenic acid, and caffeic acid [32], caffeine is a chemical with natural pesticidal properties found in coffee grounds [28], which showed larvicidal action against Aedes aegypti (Linnaeus) (Diptera: Culicidae) [49]. Probably, caffeine and other compounds found in green and roasted coffee beans may have an adulticidal action, acting in combination or not.…”

“…The coffee oil (unsaponifiable matter) consists of various compounds in free form such as diterpenes, alcohols, cafestol, and caveol [29], and those substances are responsible for the important biological effects of coffee oil as a fungicide [30] and an insecticide. Caffeine showed high efficacy as an insecticide against coffee berry borer Hypothenemus hampei [31] and demonstrated a larvicidal effect on Aedes aegypti [32].…”

The aim of this study was to evaluate the adulticidal effects of green coffee oil (GCO) and roasted coffee oil (RCO) on two species of fruit flies (Tephritidae) include Ceratitis capitata (Wiedemann) and Anastrepha fraterculus (Wiedemann). Adult flies of both species were exposed to GCO and RCO at 2%, 3%, and 4% dilutions in water under Potter spray tower. In general, exposure to GCO and RCO at the three dilutions resulted in higher numbers of dead adults of both species compared to the control populations. The mortalities increased substantially between 60–90 minutes after initial exposure. The 2% GCO dilution reached a maximum of 77.0% corrected mortality of A. fraterculus at 360 minutes. In general, the toxic effect of coffee oils occurred more rapidly in C. capitata than in A. fraterculus. GCO (2% and 3%) and RCO (2%) showed promising results for fruit fly management.

“…The shade-dried decaffeinated coffee grounds at concentrations of 150 and 200 mg/mL caused 100% mortality of Ae. aegypti larvae after exposure for approximately 4–5 days [ 28 ]. In addition, three types of dried, roasted arabica coffee grounds (light, medium, and dark) were compared with temephos for their ability to control Ae.…”

“…A study on Ae. aegypti revealed that larvae exposed to caffeine at 2 mg/mL had 100% larval mortality in 6 days after exposure (LT 50 , 3 days after exposure) [ 28 ]. Caffeine at 1.5% and 2.0% was mixed with wheat kernels, which lead to high mortality rates in Sitophilus oryzae adults (54.43% and 55.21%, respectively) after 5 days of exposure, and at the end of the experiment (2 weeks), no adults had survived [ 42 ].…”

Aedes aegypti (Diptera: Culicidae) is a vector for mosquito-borne diseases worldwide. Insecticide resistance is a major concern in controlling this mosquito. We investigated the chemical compounds in wet and dry spent coffee grounds (wSCGs and dSCGs) and evaluated the efficacy of dSCGs, wSCGs, and novaluron on the mortality and adult emergence inhibition of Ae. aegypti. We found higher concentrations of chemical compounds in wSCGs than in dSCGs. The wSCGs and dSCGs both contained total phenolic compounds, total flavonoid compounds, caffeic acid, coumaric acid, protocatechuic acid, and vanillic acid. Complete mortality was observed after 48 h of exposure to 50 g/L wSCGs, while similar mortality was found after 120 h of exposure to 10 µg/L of novaluron. The sublethal dose was a concentration of wSCGs (5 g/L) and novaluron (0.01, 0.1, and 1 µg/L) combined that resulted in a larval mortality lower than twenty percent (at 72 h) to determine their synergistic effects. The death rate of larvae exposed in sublethal combination of wSCGs and novaluron was significantly higher than that of its stand-alone. The findings indicate that the combination of wSCGs and novaluron at sublethal concentrations had synergistic effects on the mortality of Ae. aegypti larvae and could be applied as an alternative control measure.
