Human needs for wood as building materials or furniture continue to increase along with the increase in population, while the availability of wood in the forest is both limited in number and quality. This affects the particle board industry which is increasingly difficult to get good quality solid wood. One alternative to replace wood particles is Oil Palm Empty Bunches which has enormous potential to be used in the engineering field, especially as raw material for making particle boards, by utilizing acacia bark as an adhesive (matrix). To make particle board energy is needed in the manufacturing process. The energy needed in the process of making particle boards is 47,446,211.61 Joules for 25 particle boards or for 1 board for 1,897,848.46 Joules. If converted to Rupiah, the value of one particle board is Rp. 5030. When compared with factory-made prices with a size of 120 cm x 250 cm with a thickness of 1.2 cm at a price of Rp. 90,000, the particle boards that have been made are more expensive than factory-made ones.

The raw materials of the timber industry, especially furniture, are increasingly difficult to obtain in the quantity and quality needed. The development efforts carried out were utilizing Nipah coir waste as a raw material for making particle boards. Particle boards are panel boards made of wood particles or materials containing lignocellulose. Nipah plants contain 27.3% lignin and 36.5% cellulose which has the potential to be used as raw material for particleboard production. This study aims to reveal the physical and mechanical properties of particleboards made from Nipah fruit fibre with adhesive using tapioca flour. The making of particle board is done with a ratio of 90%: 10%, 80%: 20%, 70%: 30%, 60%: 40%, by giving a pressure of 100 kg / cm2. Particle testing is carried out according to the JIS A 5908 standard (2003). From this study, the optimum results were obtained in variations of 60%:40%. The particle physical properties which have an average density value of 1.15 gr / cm3 and an average moisture content of 5.8%. While the mechanical properties obtained by the value of Modulus of Elasticity an average of 21,188.93 kg / cm2. This shows the particle board variations of 60%: 40% produced to meet the JIS A 5908 (2003) standard. Based on the analysis of the quality variations 60%: 40% of particle boards can be recommended as raw materials for interior furniture.

Shortage of solid wood supply as the main raw material for the wood-based industries is cute problem faced by the world wide wood industry. Agricultural residues especially from oil palm plantation are abundantly and is therefore hoped to solve the above problem. In this context, this study would like to venture into the utilization of oil palm frond (OPF) as the potential agricultural residues for the manufacture of biocomposite panel. Raw material (OPF) mixed with the binder urea formaldehyde at three resin levels (8%, 10%, and 12%) to produce board of two density levels (550 kg/m3 and 650 kg/m3). The boards produced were tested for the mechanical strength (MOE & MOR) in accordance with the European Standard (EN 310). The results showed that the MOE values increased as the resin content increased for both board densities. The values are 1755.54 MPa to 2147.44 MPa for 550 kg/m3 and 2351.81 MPa to 2810.34 MPa for 650 kg/m3. Respectively, similar trend of increment was exhibited for the MOR values 12.18 MPa to 14.98 MPa for 550 kg/m3 and 16.62 MPa to 19.90 MPa for 650 kg/m3. In conclusion, the utilization of oil palm frond for the production of strong biocomposite material stands a great potential.

Crushed Brick

Demolition activity plays an important role in the total energy consumption of the construction industry in the European Union. The indiscriminate use of non-renewable raw materials, energy consumption, and unsustainable design has led to a redefinition of the criteria to ensure environmental protection. This article introduces an experimental plan that determines the viability of a new type of construction material, obtained from crushed brick waste, to be introduced into the construction market. The potential of crushed brick waste as a raw material in the production of building precast products, obtained by curing a geopolymeric blend at 60 °C for 3 days, has been exploited. Geopolymers represent an important alternative in reducing emissions and energy consumption, whilst, at the same time, achieving a considerable mechanical performance. The results obtained from this study show that the geopolymers produced from crushed brick were characterized by good properties in terms of open porosity, water absorption, mechanical strength, and surface resistance values when compared to building materials produced using traditional technologies.

The paper presents the results of ferriferous wastes modification process research carried on the basis of JCS “Leninobad rare metals Plant” located in the Republic of Tajikistan. The wastes for the study were taken from the western tailing. The article presents the justification of the chosen wastes as a filling material in the development of new radiation protective composite building materials. The data on the initial ferriferous chemical composition of the tailing wastes and the chemical composition of the material that passed the enrichment process is presented. The study contains microphotos of ferriferous haematite raw material particles surface before and after completing the modifying process. The paper presents and describes the study of X-ray phase analysis diffractograms of enriched iron-containing wastes before and after the modification process. The current research proves that the enrichment ferriferous wastes particles modification process is possible and as a result it can be used as a filling for the development of new kinds of radioprotective composite materials.

This paper describes the preliminary results of my PhD research within the ERC pro­ject “HisTochText”. The aim is to perform macroscopic analyses of archaeological papers from the Pelliot Collection. They are stored in the National Library of France (Bibliothèque nationale de France). Most were discovered in the oasis kingdom of Kucha, inscribed in an ancient Indian writing, brāhmῑ. The language was unknown in France. Kucha was a meeting place for many influences both western and eastern, insofar as paper analysis seeks to determine technological influences and local adaptations. Macroscopic analyses rely on traces found in the material of the paper which may be the result of the many stages in the life of the document: the raw material, the manufacturing process, the conditions of use and the storage conditions, both ancient and modern. To this day 350 fragments have been observed. Little is known about papermaking in Central Asia. As a consequence, every shred of information must be examined in order to deter­mine the differences from and similarities to paper manufacturing in Xinjiang.

Insulation Materials

 Energy consumption for residential use in Malaysia is keep increasing yearly in order to maintain the internal thermal comfort of the building. Roof insulation material plays a vital role in improving the thermal comforts of the building while reduce the cooling load of the building. Oil palm industry in Malaysia had grown aggressively over the past few decades. Tons of oil palm waste had produced during the process such as empty fruit bunch fiber. Another waste material that available and easy to obtain is paper. Paper is a valuable material that can be recycled. Waste paper comes from different sources such as newspaper, office and printing papers. This study will take advantage of the available resources which could contribute to reduce the environment impact. The aim of this study is to investigate the thermal performance of roof insulation materials using mixture of oil palm fiber and paper pulp with different ratio and thickness. This study found that the thermal performance of the paper pulp is slightly better compare to the oil palm fiber. Thermal conductivity of the particle board reduces around 4.1% by adding the 10% of paper pulp into the total density of the particle board. By adding 75% of paper pulp, the thermal conductivity of the particle board could be reduced to 24.6% compare to the oil palm fiber board under the similar condition. Therefore, from this study, it could be concluded that paper pulp has high potential to be used as a building insulation material.
