Production and Characterization of Coffee Husk Fuel Briquettes as an Alternative Energy Source

Biomass energy accounts for more than 92 percent of overall energy consumption in Ethiopia. As a result, Ethiopia is one of the world’s most biomass-dependent countries. The high reliance on wood fuels and agricultural residues for fuel harms society’s social, economic, and environmental well-being. This study aims to create and test the quality of fuel briquettes made from the coffee husk. Also built and produced are a carboniser/charcoal kiln, a manually operated molder system, and a briquette stove for burning the manufactured briquette. The carboniser converts 15 kg of raw coffee husk into 6 kg of carbonised char in 25 minutes, and the manually operated briquette molder can press 30 kg per hour. The efficiency of converting raw coffee husk into carbonised char content was 40.12%. In the geological survey of Ethiopia, the geochemical laboratory directorate received triplicate samples of the fuel briquette charcoal for analysis. Moisture content, fixed carbon content, ash content, sulfur content, and calorific value were determined using a bomb calorimeter and a ceramic lining furnace. Physical properties of fuel briquettes ranged from 10.03% moisture content, 970 kg/m3 density, 81% fixed carbon, 5.15% ash content, 0% sulfur, and 30.54 Kcal/kg higher heating value, according to laboratory results. The results of the study revealed that the coffee husk fuel briquettes produced have more positive characteristics. Fuel briquettes were cost-effective and environmentally friendly and reduced deforestation compared to firewood. This study clearly shows that briquettes made from coffee husk could be used as an alternative energy source when this kind of waste is well managed.

Analysis of the Negative Impacts of Coffee Husk on the Local Environment

In a locality wherever intense low process is completed while not appropriate waste management measures, low effluents area unit the principal reason behind organic pollution. Low husk contains caffeine, tannins, and chlorogenic acid, creating it a dangerous exposed husk. The low method has been delivery environmental issues to the environment thanks to the discharge of pollution with a large quantity of organic waste. the target of this work is to research the negative impacts of low husk on the atmosphere to scale back environmental pollution in step with the planet Health Organization, one among the foremost vital problems that enterprises confront as they look for ways to limit their use of the artifact by changing it into value-add products/applications is that the harmful impact of low husk on the atmosphere (WHO).The significance of the experiment is to form low husk as an alternate resource to switch fiber. Methylene chloride liquid-liquid extraction was developed to avoid caffeine, tannin, and CGA spectral overlapping within the three hundred -700 nm wavelength vary. The results indicated increment deadly materials that have an effect on the atmosphere. From the experiment performed low husk are often used as an alternate resource for getting composites for might applications and solve the environmental issues.

Identification of antioxidant components of Gayo Arabica Coffee Cascara using the GC-MS method

Approximately half of the coffee will become by-product in coffee processing. This by-product needs a special focus because of its content can be pollutant for nature. One of the coffee by product that underutilized is cascara, composed by pulp and husk. The major by-product of dry process is husk whereas pulp is the major by-product from wet process. Nowadays, there are various ways to utilize coffee by-product. Previous studies have shown that coffee has a potent antioxidant activity which can be a solution in dermatology problem. This research aims to identify the antioxidant component of coffee arabica husk and pulp of Gayo, Aceh Tengah, Aceh using GC-MS method. One of the compounds that identified in both coffee husk and pulp is caffeine. Caffeine is a potential natural antioxidant and it also has anticellulite effect to skin. The other compounds found in coffee husk and pulp also have benefit in dermatology. We conclude that coffee arabica husk and pulp can be a potential natural source to eradicate dermatologic problem.

Scientometric Overview of Coffee By-Products and Their Applications

As coffee consumption is on the rise, and the global coffee production creates an excess of 23 million tons of waste per year, a revolutionary transition towards a circular economy via the transformation and valorization of the main by-products from its cultivation and preparation (Coffee Husk (CH), Coffee Pulp (CP), Coffee Silverskin (CS), and Spent Coffee Grounds (SCG)) is inspiring researchers around the world. The recent growth of scholarly publications in the field and the emerging applications of coffee by-products published in these scientific papers encourages a systematic review to identify the knowledge structure, research hotspots, and to discuss the challenges and future directions. This paper displays a comprehensive scientometric analysis based on 108 articles with a high level of influence in the field of coffee by-products and their applications. According to our analysis, the research in this field shows an explosive growth since 2017, clustered in five core applications: bioactive compounds, microbial transformation, environmental applications, biofuels from thermochemical processes, and construction materials.

SISTIM PERTANIAN TERPADU PETERNAKAN KAMBING DENGAN LIMBAH HASIL PRODUKSI KOPI DI DESA TRIBUDISYUKUR LAMPUNG BARAT

Coffee husk waste has not been used optimally from the by-product of coffee bean processing production (green bean) and there is no integrated farming system between agriculture and animal husbandry. The purpose of the PPPUD service is to utilize coffee skin waste as animal feed, (2) to design healthy goat cages to optimize livestock manure waste. The implementation method is the extension and demonstration method with the stages of initial implementation, implementation of activities, and final implementation. The result of the activity is the transfer of innovation in animal feed processing training by utilizing coffee skin waste and other fiber materials, as well as the concept of a goat drum with a waste disposal site that can be used for processing waste into compost so as to increase income.Limbah kulit kopi belum dimanfaatkan secara optimal dari hasil samping produksi pengolahan biji kopi (green bean) dan belum adanya sistim pertanian terpadu antara pertanian dan peternakan. Tujuan dari pengabdian PPPUD memanfaatkan limbah kulit kopi menjadi pakan ternak, (2) mendesain kandang kambing sehat untuk mengotpimalkan limbah kotoran ternak. Metode pelakasanaan dengan metode penyuluhan dan demontrasi cara dengan tahapan pelaksanaan awal, Pelaksanaan keiatan, dan Pelaksanaan akhir. Hasil deari kegiatan adalah transferinovasi pelatihan pengolahan pakan ternak dengan memanfaatkan limbah kulit kopi dan bahan serat lainnya, serta konsep kendang kambing dengan tempat pembuangan limbah dapat dimanfaatkan untuk pengolahan limbah menjadi pupuk kompos sehingga meningkatkan pendapatan.

Polyethylene-coffee husk eco-composites for production of value-added consumer products

The annual worldwide production of coffee exceeds 10 million tons, and more than 90% of this production is waste, including the husk. On the other hand, plastic consumption increases every year, and sustainable alternatives are necessary to decrease it. This work arises to solve these two problems, and seeks to produce products at an industrial level from polyethylene/coffee husk eco-composites. Both Low Density Polyethylene and High Density Polyethylene were used, and the amounts of coffee husk added as filler were 20 and 40 wt%. The composites were characterized by different morphological, thermal and mechanical techniques. Scanning Electron Microscopy images showed husk particles embedded in the polymer matrix, but with some gaps between the polymer and the filler, because no compatibilizer agent was used. The addition of large amounts of natural filler negatively affected the tensile strength and elongation at break, but increases eco-composites crystallinity, and hence, their Young modulus and hardness. The industrial applicability of the eco-composites was verified through the production of five different consumer products by extrusion and injection processes, using mixtures with 40 wt% coffee husks. All products were obtained without significant defects. If only 3.25 wt% of the polyethylene products produced each year in Colombia did so with the eco-composites developed in this work, all the coffee husk produced in the country would be used, and the emission of about 5.390 million m3 of greenhouse gases would be avoided.
