“…In the project area, the wet method is widespread. This method generates the following wastes: pulp (43%), mucilage (27%) and husk (6%) [14,15]. Incorporation of new alternatives sources of energy allows the transition toward sustainable social and economic progress, reducing emissions stemming from energy production and consumption that depend, for the most part, on fossil fuels such as coal, oil and gas.…”

Coffee is one of the most representative agricultural products in Colombia; several factors related to how it is produced, processed and marketed make it particularly important in post-conflict situations. The cultivation of coffee has acquired a very important role in the post-conflict stage that Colombia is experiencing. The rural areas hit hardest by violence are now seeing how improving agricultural conditions can help promote sustainable development and build peace in their regions. In coffee processing, women play an important role, with between 20% and 30% of coffee farms around the world being female-operated and up to 70% of labor in coffee production being provided by women. Women not only contribute to coffee processing, but they are also responsible for family activities such as cooking, and those activities are often made in wood stoves, thereby increasing their health risk. Against this background, this study presents the design and implementation of a biodigester fed by waste produced at Coffee Production Units (CPUs) located in the rural area of Tolima department in Colombia (an important scene of the armed conflict) in order to produce biogas for domestic cooking activities. Results show that implemented biodigester can produce between 1362 and 1597 kg/day (1.1704 and 1.3604 Nm3/day), which is enough energy for domestic activities for a family of four. Furthermore, it demonstrates benefits in the economic, social and environmental context of CPUs. Additionally, due to the importance of women in coffee production, this paper also evaluates the impact of the implementation of biodigesters in farms, which has shown that biodigester implementation positively impacts the production activities and activities performed by women, thereby increasing their life quality.

“…Employing a biogas digester should result in double benefits: a renewable energy source for coffee production (i.e., drying, lighting, power) and organic solid and liquid fertilizers for coffee cultivation (Abdullah et al, 2020;Novia et al, 2021;Setyobudi et al 2021aSetyobudi et al , 2021bSusanto et al, 2020). Various types of the digester are advised by certain experts: Mulato and Suharyanto (2010) utilized a floating drum in Indonesia; Centro Nacional de Investigación del Café (CENICAFE) developed a Modular Anaerobic Treatment System (MATS) for coffee farms in the Colombian mountains (Bermeo-Andrade et al, 2020);Hernández-Sarabia et al (2021) proposed tubular, or bag biodigester (Taiwan type -PVC 1005 geomembrane) in Colombia; Bombardiere (2006) reported the use of thermophilic Continuous Stirred Tank Reactor (CSTR) in Mexico. Rattan et al (2015) suggest Upflow Anaerobic Hybrid Reactor-continuous (UAHR) and intermittent aeration system.…”

The research aimed to reduce the amount of coffee pulp (CP) as a pollutant and turn it into Coffee Cherry Fluor (CCF) as a functional food. CCF is expected to serve a function as a non-heme iron source to treat anemia. Further, reusing CP should be able to boost the circulation of economy. Six CP samples from three Arabica coffee areas (highlands of Mount Batur, Mount Ijen, and Mount Arjuno) in Indonesia were compared to La Boite CCF, a commercial product made in Brazil. Variables observed were iron contents which is determined by Inductively Coupled Plasma Optical Emission Spectrometer, vitamin C contents as enhancers by Iodimetric titration, total phenol contents as inhibitors by Folin-Ciocalteu method, tannin contents by spectrophotometry method, lignin contents by Van Soest method, total plant count by ISO 4833-1, and antioxidant capacity by IC 50 in the DPPH scavenging assay. Sample disparity significance was statistically determined by ANOVA, followed by Tukey test at 95 %. Sample resemblance with La Boite CCF was tested using Principal Coordinates Analysis (PCoA) and then presented in Heat Map. Conclusively, Mengani CCF and Mengani CP Estate samples are similar to La Boite CCF regarding vitamin C and inhibitor contents. It is suggested to reduce the temperature of the artificial drying device in Mengani. Further research should cover heavy metal contents, proximate analysis, and the detail of amino acid contents as research observed variables; expanding this research in vivo to study non-heme Fe's bioavailability should also be conducted.

“…It is also known that large volumes of water are used during coffee washing, generating associated socio-environmental impacts on water bodies (Ruiz-Najera et al, 2021). In this sense, economic and easy-to-apply technologies should be adopted (Hernández-Sarabia et al, 2021). An important factor is training in good coffee washing practices, through modified tanks that provide good water use during washing (Lopez Blanco, 2014).…”

The objective of this research was to determine water quality in small-scale coffee production units in the Amazon Region, Peru. The characterization of the factors associated with coffee farmers was collected through surveys. The Standard Methods for the Examination of Water and Wastewater (APHA) method was used to determine the physicochemical and microbiological parameters of the incoming water (AE) (water for human consumption) and the outgoing water (AS) (wastewater from coffee washing). The results indicated that the coff ee growers do not have adequate technology for washing the coffee and that they use water for these activities. In the characterization of the water, significant differences were found between the parameters of the AE and the AS, where the pH of the AE ranged from 7.00 to 7.32 and the pH of the AS from 3.76 to 4.44. The turbidity of the AS showed high values of 1814.47 NTU. Total Coliforms (TC) and heavy metals such as copper and chromium all increased in value up to 0.20 and 0.15 ppm in the AS compared to the AE. The characteristics of the water quality consumed by the coffee growers are poor and values above Peruvian standards were found.
