    Summary:Various sizes of high-density biomass briquette, named 'Bio-coke,' were produced from spent green tea grounds. The mechanical properties at room temperature of the Bio-coke samples were investigated using a compression testing machine. From the results, the relationship between the specimen size of Bio-coke and the ultimate compressive strength at room temperature showed that the ultimate compressive strength depends on the specimen size of Bio-coke. The maximum value of the ultimate compressive strength among the different specimen sizes of Bio-coke was at 67 MPa, obtained from the 12-mm diameter sample. In addition, at 12 mm diameter or smaller, there is hardly any difference in the ultimate compressive strengths measured. Hence, the cold compressive strength properties are divided into two groups based on the uniformity of the structure of the main components along the horizontal cross section of a Bio-coke. Results indicate that the state of the structure, composed of cellulose, hemi-cellulose, and lignin, appears to be consistent resulting from uniform permeation conditions at the 12-mm diameter or smaller samples. Meanwhile, at diameters of 20 mm or larger, the condition of the periphery of the samples were not consistent with that of the middle region because of the temperature, stress gradient and number of void occurring inside the Bio-coke caused by specimen size effect.

    Summary:  People in the world have been eating rice for a long period of time, especially in Asian countries including Japan that considers rice as its staple food. Like many agricultural products, agricultural waste like rice husk and rice straw are a big disposal problem. One of the solutions for this problem is solidification. It is better to use the solid as fuel for heating and create a cycle of local production for local consumption. In this study, we established formation temperature and particle size as parameters and produced solid fuel (hereinafter referred to as BIC) from rice husk with high-density and high-hardness solidification technology. The apparent density from weight and volume of BIC and assessed compressive strength of BIC with compression test under room and high temperature was calculated. From derived results physical and mechanical properties were considered. Results showed that rice husk of small particle size had better lignin reaction than large one. However, it is also revealed that the maximum compressive strength at room and high temperature was both weak in the case of crushing the particle size of the rice husk too small.

    Summary:   Primarily, Japan has very little sources of coal, oil, and natural gas. As a result these primary energy sources are imported from other countries. The development of Japans domestic primary energy sources is necessary to reduce its dependency on foreign energy import. Above all, energy derived from biomass sources are sustainable energy resources. In this study, various sizes of high-density biomass briquette named 'Bio-coke, whose technology was based on our patent (PAT.-No.4088933), were produced from green tea grounds. The physical properties at high temperature of each size of Bio-coke were studied, and their maximum compressive strength and Youngs modulus were estimated by a compression test at a temperature of 973K. From the results obtained, the relationship between the size of Bio-coke and the maximum compressive strength or Youngs modulus could be approximated by a linear function or an exponential function.

    Summary:  Biomass is one of the sustainable energy sources and is the most suitable natural energy for storage and transport. We are suggesting a high hardness biomass briquette made from any plant biomass as an alternative coal coke. The high hardness biomass briquette is named 'Bio coke', described as 'BIC' below, and it achieves 10 to 20% substitution of coal coke for practical cupola furnace use. We, in the present study, examined the influence of composition on combustion property of BIC made from coffee residues. The coffee residues were assorted to outer skin (outer skin and pulp mixture, described as 'OS' below), inner skin (parchment and silver skin mixture, described as 'IS' below) and coffee bean grounds (instant coffee production residue, described as 'IC' below). BIC specimens were composed of IC100%, IC50%+OS50% and IC50%+IS50%, OS100% and IS100%. Measurement of ignition delay (time from heating start to flaming combustion start), duration time of flaming combustion and char combustion, and thermogravimetry were conducted under 698K air environment. As a result, the ignition delay and the duration time of char combustion were affected by not only combustion property of each component but crack generation condition during heating process. The ignition delay and the duration time of char combustion were shorten due to enlargement of reaction surface area caused by the crack generation. It is, additionally, considered that the crack generation condition could be controlled by mixing of components which have different thermal decomposition and combustion properties.

    Summary:  At present, Japan is even in a bigger energy problem since the oil crisis. Conversion to renewable energy has become an urgent need among many problems in Japan, one in particular, the carbon-dioxide emission that is increasing at an alarming rate. Bio-coke was developed in this laboratory and is reaching commercial level. This study discusses the relationship between the retention time of formed Bio-coke and its specific surface area. During the formation time of about 5 minutes, a specific surface area of 0.5 m2/g is achieved, and a cold compressive strength of 60MPa is attained. When the specific gravity reaches at least 1.395, the specific surface area is reduced to about 0.5 m2/g.

    Summary:We produced high-density solid biomass (hereafter called Bio-coke) from broccoli, dead cherry tree leaves, and seed of mango based on our patent (PAT.-No.4088933) as one of the utilization methods of various unutilized biomass. The compressive strength of each kind of Bio-coke under room temperature was measured with a compression testing machine. The experimental results showed that the ultimate strength was related to the carbon content of broccoli, seed of mango, and dead cherry tree leaves, and the relations were close to linear.

    Summary:Effective utilization of biomass resource rapidly has been promoting since the government adopted the 'Biomass Nippon' strategy at a cabinet meeting in 2002. Especially, the energy conversion technology of applying biomass has been expected from a point of view of environment and resource conservation. However, the energy conversion technologies are developed only for woody and herby biomass, and not for all of biomass. A stable supply of large quantity of biomass will be pressed in the future because the conversion technology must expand to use a variety of biomass. This study is to consider ways by various quantitative correlation analyses between the atomic composition and thermal decomposition of various biomass samples. The results found that thermal decomposition analyses of various biomass resources have correlations between atomic composition properties and exothermic properties.

    Summary:In Japan, 7.50 million tons of rice straw was incinerated and plowed under soil. This abundant resource of rice straw is useful as alternative energy for recycling-based societies and also in possibly activating agriculture that is dependent on local production for local consumption. We aimed to effectively use unutilized rice straw by producing Bio-coke, which is a new briquette (in the rest of this document referred to as the BIC) with high density and hardness, and evaluated characteristics of rice straw BIC because the relationship between specific gravity and specific surface area of BIC is not well known. Additionally, it is seems that the specific gravity and specific surface area at the periphery of BIC may affect its combustion characteristics. In this study, one of the aims is that BICs are produced with various specific gravity and specific surface area as a parameter. It was confirmed to be able to produce BIC with different specific gravity and specific surface area at the periphery of BIC by changing manufacturing conditions of BIC and be led the relationship between the specific gravity and the specific surface area. After that, it was examined that difference of the specific gravity or the specific surface area at the periphery of BICs relates the ignition delay time as one of the combustion characteristics derived from burning BIC with different specific gravity. As a result, it was led that the relationship between the specific gravity or the specific surface area at the periphery of BICs and the ignition delay time was a direct proportional relationship.

    Summary:Fossil fuel, like oil, coal, natural gas and so on, has sustained our local infrastructure on the side of Energy. However, the fossil fuel has various problems at the point of the quantity of resources and environmental burden. We need to rapidly develop sustainable energy resources to substitute for the fossil fuel. In this study, we tried to measure combustion characteristics of alga of Lake Biwa Bio-coke. Bio-coke is a fuel as an alternative energy source to coal. We derived that alga of Lake Biwa has a lot of ash, including about 25%, in comparison with other land biomass from the result of thermal decomposition characteristics. Concerning the combustion characteristics, ignition delay time for alga of Lake Biwa BIC is about one and a half times longer, and flame and char combustion time is shorter than Japanese cypress BIC. Thus, although the BIC produced from alga of Lake Biwa has many demerits for combustion performance, the research of alga BIC as adiabatic material is expected as a next step.

    Summary:Unused biomass resources are classified as those that have no value as a resource after being used and those that still have potential value. Socks, towels, pencils, miscellaneous paper wastes, etc., have potential thermal energy value. From the reduction of carbon dioxide emissions that cause global warming and the viewpoint of fossil fuel resource depletion problem, high density and high hardness solid fuel has been attracting attention as a new solid bio-energy in which self-sufficiency in Japan is possible. Assuming a pair of socks is approximately 40g, 50,000 tons of discarded socks can be collected. On the other hand, with 30 t of abandoned pencils already available, it is thought that a total of about 1,950 t can be collected annually. Mechanical compressive tests in this study revealed that the physical properties of socks Bio-coke include a cold maximum compressive strength of 84 MPa and a hot maximum compressive strength of 2 MPa at 973 K.

    Summary:In this study, we produced bio-solid fuel which has different density and observed its combustion phenomenon. Through the observation of combustion for bio-solid fuel with different density from 0.9 ~ 1.4 g/cm3, we quantitatively derived ignition limit of bio-solid fuel about the difference of density. Also, we shot the surface combustion of bio-solid fuel with the different density. Thus, we confirmed time continuing the solid combustion and observed the situation of spread of combustion into the inside of solid fuel.

    Summary:Low Carbon Society started based on a new concept by METI in JAPAN. A low carbon project has many programs, transportation or carbonization technologies and dust division motion act etc. Our projects carried out feasibility studies of alternative energy for fossil resources with the new solid bio-fuel, Biocoke. Biocoke has special physical properties of high density and hardness. One of our projects is that this report discusses the mono-fuel combustion boiler developed exclusively for Biocoke. The herbaceous plant, Itadori, is used as a biomass raw material to produce Biocoke. The Biocoke boiler has the hybrid thermal exchange system by hot water and air as itself performance. On the other hand, this project proposed a new thermal energy distribution system based on planter agriculture for high efficient utilization of thermal energy. The total thermal efficiency of Biocoke boiler is 75% over at the maximum. In winter, Biocoke boiler worked in high performance condition during 5 months under the extremely cold environment at -30℃. This project suggested Biocoke is able to completely substitute for fossils resources such as kerosene/heavy oil. Accordingly, this project found that Low Carbon Society can realize by high value added industry and low carbon agriculture under economic action in the winter season.
