Utilization of durian peel waste and young coconut waste into biobriquettes as a renewable energy source

The increase in durian fruit production in Indonesia in 2021 by 19.40% and coconut fruit production by 1.47% which will be directly proportional to the increase in durian skin waste and young coconut waste produced. These wastes have not been optimally utilized so that their availability is quite a lot in the environment. Both wastes contain large amounts of cellulose, namely 50%-60%. The cellulose element will affect the carbon value so that with this content, waste and young coconut waste can be utilized as raw materials in making briquettes. This utilization is one of the efforts in utilizing waste into renewable energy sources. This study aims to obtain the best briquette characteristics from a mixture of durian peel charcoal with young coconut charcoal in accordance with the briquette characteristics in SNI 01-6235-2000, and to determine the economic value of briquettes. This research method was conducted experimentally, by mixing durian peel charcoal with young coconut charcoal as raw material for briquettes as many as six variations, namely (90% : 10%), (75% : 25%), (60% : 40%), (45% : 55%), (100% durian peel charcoal) and (100% young coconut charcoal). The results showed that sample 3 (60% : 40%) was the best briquette with the highest fix carbon value (72.81%), calorific value (22,124 J/gr or 5,284.23 cal/gr), moisture content (13.83%), volatile content (1.69%), ash content (11.67%) and compressive strength (0.752 kgf/cm2). The SEM test results showed a clean morphological structure of the briquettes with tight voids. The characteristics of biobriquettes produced through six briquette samples meet the standards of volatile content and calorific value of briquettes, and the moisture content, ash content, fixed carbon content, and compressive strength do not meet the characteristics of briquettes according to SNI 01-6235-2000.

Technology for Producing Heat From Composite Coal Fuels in Advanced Oven for Municipal and Household Use

The problem of rational use of coal remains relevant; currently, various technologies have been developed for producing composite solid fuels, briquettes with various binding materials from brown coal deposits in Kyrgyzstan. The widespread use of composite solid fuels (CSF) and coal briquettes in industry, everyday life and public utilities, in our opinion, is limited by two reasons: excessively inflated requirements of existing standards for the physical and mechanical characteristics of briquettes as a product; poor knowledge of optimal conditions for burning briquettes. Our research shows that compressive strength in the range of 15-20 kgf/cm2 provides the necessary strength for the degree of abrasion during transportation and storage of large-sized rectangular CSFs. Reducing the strength requirement to the value indicated above makes it possible to form briquettes from unsorted culm. Among the numerous known binders for briquetting, inorganic types of clays and loams, which are ubiquitous, deserve special attention. It has been established that clays and loams provide the strength of the CSF over 20 kgf/cm2. For the purpose of beneficial use of low-grade fine coal, we carried out briquetting and combustion testing of the resulting briquettes. It has been established that when briquetting coals from the Zhatan and Kumbel deposits with a clay binder, with an increase in the content of fine coals in the composition, the burning time of the briquette increases, as well as the combustion of the combustible mass increases, and the temperature in the combustion space increases. It has been shown that with the help of appropriate minor modifications of standard household stoves it is possible to significantly increase the combustion efficiency of all types of low-grade fuel, including lignite high-ash CSF.

Variations of Coconut Shell, Rice Husk, and Bagasse as an Alternative of Briquettes Materials

The current energy condition is getting thinner meanwhile people's daily lives still use a lot of energy derived from fossil fuels so that its use is increasing with limited availability. An alternative to reduce the use of fossil energy is by utilizing waste biomass as an energy source one of them is briquetts. This study aims to analyze the characteristics of briquettes from a variety of briquette mixtures made from coconut shells, rice husks, and bagasse. The method used is survey and experimental. The survey of sampling coconut shells was carried out in the Seberang Ulu I area, rice husks in the Pegayut area, and bagasse was obtained at the ice cane traders in the Seberang Ulu I area. The data obtained were presented in graphical form and analyzed descriptively. The results obtained are the water content in the variation of the combination of briquette-making materials ranging from 4.23 - 5.13%, ash content of 7.6 - 7.86%, the density value obtained is 0.55 - 0.59 g/cm3, the compressive strength value is 25.67 - 37.33 kg/cm2, and the calorific value is 4756 - 4865 cal/gr. The results showed there is not significant differences in moisture content, ash content, and compressive strength, while the density and calorific value showed significant differences.

Potential of Coffee and Cocoa Shell Waste as An Energy Source: Analysis of Characteristics of Briquettes From Coffee and Cocoa Shell Waste Through The Carbonization Process

This research aims to compare the characteristics of briquettes as an energy source produced from coffee shell waste and cocoa waste. The briquette-making process involves carbonization to produce charcoal as the primary raw material for briquettes. Carbonization time varies, influenced by the type of waste and size of the material. After that, the charcoal is reduced and sifted into fine and coarse powder. Briquette molding uses pressure using a pipe as a mold. The characteristics of briquettes are analyzed through water content, density, burning rate, and ash content. The research results show differences in characteristics between coffee and cocoa waste. The carbonization process affects the time and mass difference of raw materials. Cocoa pod shells require the longest (±35 minutes), while cocoa bean shells require the shortest (±17 minutes). Next, making briquettes involves molding and pressing using a pipe as a mold. The results showed that waste cocoa pod shells and cocoa bean shells produced more briquettes than waste coffee pod shells and coffee bean shells. The moisture content of briquettes from all types of waste meets the standards, but the density of the raw material for coffee husk waste is low, while the briquettes have a high density. The burning rate of briquettes varies, with cocoa bean shell briquettes having the fastest burning rate and producing much smoke. The ash content of cocoa pod husk briquettes exceeds the standard, while cocoa bean husk briquettes have low ash content. The density of the raw material is correlated with the moisture content of the briquettes. The highest burning rate occurs in cocoa bean shell briquettes, influenced by low density and high water content. The ash content of the briquettes meets standards, except for cocoa shell briquettes. This research proves that cocoa and coffee shell waste can be processed into briquettes with different characteristics.

Characterization of Biobriquette from Carbonized Durian Peel Using Coconut Shell as the Binder

This research aimed to study the characteristics of carbonized durian peel biobriquette using tar as a binder. A 1:10 ratio of binder and carbonized durian peel was used. The 25, 50, and 75% (coded as P1, P2, and P3, respectively) tar were used as a binder alongside tapioca flour to produce a binder with different tar concentrations. The briquette characteristics determined moisture content, ash content, calorific value, density, and water-absorbing capacity. Moisture content ranged from 9.32% to 9,41% for treatments P1 to P3, while the ash content ranged from 12,29% to 13,09%, showing no significant difference among the treatments. Massive difference was observed in calorific value, as P1 gives 5106/35 cal g-1 calorific value while P2 and P3 give 9267.56 and 9694.53 cal g-1, respectively. The density observed was relatively low, ranging from 0.5029 g cm-3 to 0,5685 g cm-2. As for water-absorbing capacity, P3 absorbed the least amount of water, 29.43%. From this research, we can conclude that coconut shell tar has the potential to be utilized as a binder in forming biobriquette from carbonized durian peel.

Briquette Characteristics of Mixed Charcoal of Taro Peel and Rice Husk

Petroleum reserves in Indonesia are running low, as well as fossil energy. If these conditions are not handled appropriately and quickly, the Indonesian nation will experience a petroleum crisis. Biomass briquettes are made from a combination of rice husks, taro husks, and a tapioca flour adhesive, and they will be produced as a byproduct of Indonesia's extensive agricultural sector and the growing taro industry. The use of taro skin in conjunction with other raw materials gives this study an element of originality. The purpose of this research is twofold: to disseminate knowledge about the potential of biomass waste, and to analyze how different biomass waste mixtures affect the briquettes SNI-required properties. An experimental approach was used for this study. In this experiment, three different weight ratios of taro husks to rice husks (KT:50%, KT:75%, and KT:100%) were employed as the primary raw materials. Five-and-a-half percent of the briquette dough's overall weight comes from tapioca flour's role as an adhesive. Preparation of briquette materials, carbonization, briquetting, and testing for biomass briquette characteristics are the first steps in the study approach. The calorific value, moisture, ash, volatile matter, binding carbon, and density tests are all part of this battery of analyses. The highest grade briquettes have a calorific value of 3,993.92 cal/g and are made from 100% KT briquettes. KT briquettes with a 75% moisture content are the highest grade briquettes available. At 22.90%, KT briquettes have the lowest ash level of any high-quality briquettes. Briquettes made from 100 percent KT, or 0.09 percent volatile matter, are the highest grade available. KT briquettes, which have a bonded carbon content of 74.59%, are the highest grade option. 50% KT briquettes, with a density of 0.48 g/cm3, are the highest grade briquettes available.

Evaluation of physical and combustion characteristics of briquettes of palm fruit fibre and maize chaff using cassava extract as binder

The selection or choice of agro-waste briquettes for domestic and industrial cottage applications depends on the fuel properties. In this work, Palm fruit fibre (PFF) and maize chaff were separately sun dried for seven days to remove moisture. The dried materials were separately ground using electric milling machine. They were then reduced to mesh sizes of 1.18, 1.70, 2.36 and 3.35 mm respectively. Filtered liquid extract of cassava was collected and dried for five days to form the binder. Different concentration of biomass materials were prepared by blending palm fruit fibre at 20, 40, 60 and 80% concentrations with maize chaff. Shattering index, ignition time, water boiling time, burning rate, specific fuel consumption, percentage ash content and calorific values of PFF and maize chaff briquettes were investigated. Results showed that shattering index reduced with increase in particle size and increased with reduction in particle size. Highest and lowest durability were obtained at particle sizes of 1.18 and 3.35 mm respectively. The ignition time decreased with increase in particle size of briquettes. 1.18 mm particles give the highest ignition time (54.88 sec.) and 3.35 mm particles gave the lowest ignition time (24.24 sec.). Therefore, increasing the particle size increases the ignitibility of the briquettes. It was observed that the ignition time increases with increase in percentage composition of palm fruit fibre in the briquette samples with a maximum ignition time of 29.66 seconds at 80% PFF. The specific fuel consumption, shows that there was an initial increase from 50.0 g/ltr to 55.0 g/ltr, after which it decreased continuously with increase in particle size. Water boiling time, showed an inverse relationship with particle size. However, water boiling time between 2.36 and 3.35mm particle size has a more pronounced variation in comparison with preceding values. Higher calorific value 31,514.05 and 31,004.30 kJ/kg of PFF and maize chaff briquettes were recorded.

Impact of Biomass Moisture Content on the Physical Properties of Briquettes Produced from Recycled Ficus nitida Pruning Residuals

Despite its vital importance for life and societal development, energy is a source of conflict and war in many places worldwide. It is also a source of pollution and harmful natural phenomena that affect human life and the environment. These factors have led scientists to consider alternative clean, cheap, and eco-friendly renewable energies. Examples include briquettes consisting of compressed agricultural waste, such as pruning residuals. Hence, this study aimed to evaluate the characteristics of briquettes derived from the pruning residuals of Ficus nitida trees. The results indicate that moisture content was the main factor affecting the physical properties of the produced briquettes. The ideal moisture content for producing high-quality briquettes was 8%. With this moisture content, the briquette durability was 96.9%, the bulk density was approximately 0.18 g·cm3, the compressive strength was 18.5 MPa, and its calorific value was 3250.7 Kcal/kg (17.38 MJ/kg). In conclusion, our research confirms the high quality of briquettes made from the pruning residuals of F. nitida and their promising potential as an energy source.

Effect of chemical structure on mechanical-seepage characteristics of briquette under different heating temperatures

Based on the low strength and high permeability of briquette coal (BC) used in physical simulations of coal mine disasters, we propose a new briquette production method that can improve the mechanical strength and reduce the permeability of BC. The reduction of physical simulation experiments of coal and gas outburst was improved, which is of significance for the prevention and control of coal mine gas disasters. Based on this method, we developed a set of briquette hot-pressing systems and optimized the proportion of coal powder used in the briquette formation process. Mechanical property and seepage tests of the briquettes were carried out under uniaxial and triaxial compression. The effects of different temperatures on the physical (size, density, ignition loss rate) and mechanical (Poisson's ratio, elastic modulus and compressive strength) coal parameters and the effect of the permeability were analyzed using scanning electron microscopy, X-ray diffraction, and Fourier transform infrared spectroscopy analyses. The morphology and pore, crystallite, and molecular structures were used to determine the cause of the increase in the mechanical strength of BC. Based on the packing density theory, the optimal ratio of the 40–60, 100–120, and 180–200 mesh particle sizes is 91.77:5.87:2.35. With the increase in the temperature from 150 to 450 °C, the microstructure changes from loose to compact, the number of pores and cracks increase, the degree of order of the microcrystalline structure gradually increases, the distance between the microcrystalline layers d002 continuously decreases, aliphatic chains shorten, and the aromaticity increases. The rate of the change of the loss rate and density of the hot-pressed briquette first increase, then decrease, and then increase again. The mechanical parameters (strength and elastic modulus) first increase and then decrease, whereas the Poisson's ratio first decreases and then increases, and the permeability increases. Considering the density, strength, and permeability of hot-pressed briquettes, the optimal heating temperature at which the similarity between the hot-pressed BC and raw coal is the highest at 300 °C.

Characteristics of briquettes from plastic pyrolysis by-products

Pyrolysis has been proven as a method to reduce plastic waste and produce useful products, especially liquid fuels. However, plastic pyrolysis also produces gases and char as by-products which are being investigated for useful products. Therefore, our present study aims to investigate the char characteristics of plastic pyrolysis for further use as briquettes. Seven samples of char by-products from the pyrolysis process of low-density polyethylene (LDPE) plastic at various reaction temperatures and catalyst types were studied. The proximate test is used to determine the properties of char such as moisture content, ash, volatile matter, and fixed carbon while the bomb calorimeter is used to determine the calorific value. Briquettes are formed by mixing 4 grams of char and 0.5-1 gram of binder (1% starch and 90% water). The briquettes were formed into solid cylinders with a diameter of 1.75 cm and formed with a pressure of 10 kg/cm2. Furthermore, the impact resistance index (IRI) was used to test the performance of the briquettes and showed an IRI value between 100 and 200. However, of the seven char samples tested, three of them were impossible to process into briquettes because they melted during the combustion test.

Production of bio-briquettes from pineapple peels and sewage sludge as an alternative renewable energy

The need to investigate an eco-friendly and renewable alternative energy source has been prompted by issues relating to the depletion of conventional fuel resources. One of the best green energy alternatives is bioenergy, which also encourages the sustainable use of agricultural waste. This study was carried out to investigate the utilization of pineapple peels for bio-briquette production. This study aimed to determine the characterization of bio-briquette by using different variations in the composition of sewage sludge, pineapple peels, and adhesive types, and to investigate the effect of different adhesive types on briquette characteristics. This research used rejected papaya, cow dung, and starch as the adhesive. The sludge, peels, and adhesives were blended in the ratios of (90:0:10); (70:20:10); (60:30:10); (30:60:10); (20:70:10); and (0:90:10). The result shows that the optimum briquettes were produced from (0:90:10) composition which was 0% sludge, 90% peel, and 10% starch. These briquettes with (0:90:10) composition had a water content of 5%, ash content of 11%, volatile matter of 13%, fixed carbon of 76%, and calorific value of 4,753.99 Cal/g. Calorific values increased as the composition of pineapple peels increased. Moreover, briquette with starch as the adhesive had better physical properties compared to adhesive from rejected papaya and cow dung.

Fast-growing species have been increasingly developed in recent years, and among them, those cultivated to obtain combustible woody biomass have shown rapid development. The purpose of this research study is to highlight the properties of the briquettes and pellets obtained from energetic willow compared to the briquettes and pellets obtained from oak biomass. Methodologies have been based on international standards and were used to find the physical, mechanical, and calorific properties of the two types of briquettes and pellets. The results did not highlight a significant difference between the two categories of briquettes and pellets obtained from the two hardwood species (energetic willow and oak). Characteristics such as the calorific value were 20.7 MJ/kg for native pellets and 21.43 MJ/kg for torrefied pellets of energetic willow, as well as the compressive strength of 1.02 N/mm2, surpassed the same characteristics of briquettes and pellets obtained from oak biomass. Other characteristics of energetic willows, such as energetic density of 18.0 × 103 MJ/m3, splitting strength of 0.08 N/mm2, shear strength of 0.86 N/mm2, and abrasion of 1.92%, were favorably related to the oak biomass. The ecological analysis highlighted the high potential of the ecological willow in a period when the quantities of carbon dioxide released into the atmosphere by human activities are very high, and its sequestration by existing forests is insufficient. As a general conclusion of this research study, it can be stated that the two categories of briquettes and pellets obtained from the woody biomass of the energetic willow and oak species have similar characteristics, which can be used separately or together in ecological and sustainable combustion.
