The continuous extraction of natural non-renewable resources such as lime and natural aggregates for the production of concrete, the introduction of sustainable development to overcome the issues of natural resource depletion has been gaining increased attention. The main objective of this research is to address the potential use of both agricultural and industrial wastes namely Rice Husk Ash (RHA) and Expanded Polystyrene (EPS) respectively as raw material for the production of ‘Green’ lightweight concrete bricks. RHA was used as partial cement replacement, while the EPS was used as partial aggregate replacement in the mixes. Five different mix proportions were prepared. Sample A acts as the control sample (without RHA) and has a Cement: Sand: EPS ratio of 1.0∶ 1.5∶ 1.5, while samples B, C, D and E have RHA replacements of 5%, 10%, 15% and 20% respectively. The samples were tested for fresh concrete namely slump, fresh concrete density and air content while the hardened concrete properties tested were sorptivity, compressive strength and thermal conductivity. It was determined that EPS RHA concrete brick gives promising results.

ECO-RUBBER is a project aimed to implement a real industrialization of an eco-friendly tyre recycling and rubber sintering production system to place on the market high-quality recycled-rubber urban products. To reach this main objective, the optimization of the existing grinding and sintering lines is being carried out in order to enhance mechanical properties. Furthermore, functional and emotional criteria have been taken into account to prepare an initial design of the bollard, the selected urban furniture to demonstrate the advantages of an application made of recycled rubber. Then, finite element analyses have been implemented in order to optimize the design and minimize the amount of material to be used. Further work is yet to be done: a first prototype will be sintered and tested. Moreover, in order to enhance the perceived quality of sintered tyre rubber crumb products, an eco-label will be proposed.

The study found construction and demolition (C&D) waste comprising more or less a homogenous composition from various sources either construction or landfill sites or Klang Valley. The largest components of C&D waste are concrete, aggregate and rubbles followed by soil, wood, metals and roofing materials. In Klang Valley, 88% of the C&D waste generated is from residential buildings while 9% from commercial and 3% from government buildings resulted from increased demand of housing and commercial buildings. A majority of C&D waste dumps to the private land or illegal dumpsites while only 20% of them disposed in legal landfills. This is due to most of the legal landfills are reluctant to accept C&D waste because of their limited space. This paper attempts to document a profile of C&D waste generation and disposal into a one record to allow industry-wide dissemination though it has a limitation of facts and figures for representing the country as a whole. Therefore, there is a need for an authorized body in Malaysia to be responsible for collection, classification, analysis and storage of all types of C&D wastes and a centralized database of C&D wastes to serve a paradigm shift of good waste management practices in the construction industry.

High quality transformer oil is required to increase the reliability and the life time of the transformer. This oil carries information about the operating condition of the transformer. Therefore, the transformer oil properties should be monitored in order to give early warnings and maintain the transformers efficiency. When the oil quality is decreased, it should be either changed or regenerated. Transformer oil regeneration is carried out using adsorption on Activated Carbon (AC) produced from waste date-pits. After adsorption, drop in density, viscosity, neutralization index and metallic contents were observed, whereas adsorption resulted in an increase in interfacial area. The properties of the regenerated oil after adsorption was found to approach the acceptable standards, which clearly demonstrate the potential of using locally made AC from waste date-pits as an adsorption agent for transformer oil regeneration.

This paper presents an abstract model for production facilities which is supposed to serve as a universally applicable base for the simulation of energy flows in a manufacturing company. Its goal is to enable integrated analysis and simulation, considering production processes, machinery, systems, and buildings as a whole in order to find the best leverage to optimize overall energy consumption. The requirements on the model and its general structure are explained as well as how its parts relate to specific aspects of a production facility. Furthermore, considerations for implementing a complex simulation on its basis are discussed.

TG-FTIR was used to study the pyrolysis of cellulose with catalysts. The three zeolites (HZSM-5, H-β, USY) all inhibit the main decomposition of cellulose and reduced the formation of oxygenated compounds (such as aldehydes, acids and esters) effectively. HZSM-5 has the best deoxygenation activity. USY catalyzes the conversion of oxygenated compounds into iso-alkanes, and H-β promotes the formation of CO2 significantly.

Wireless Senor Network (WSN) is an advanced sensing network consist of mini-nodes having abilities of sensing, processing and wireless connectivity. Due to distinguish capabilities, it is highly demanding network for reliable monitoring and analysis of physical parameters over any geographical area. Designing of routing protocols faces many challenges due to limited resources of WSN nodes like short memory, limited energy and limited processing. This paper has a qualitative study on four multicast routing protocols with energy-efficiency perspective. MAODV (Multi-cast Ad-hoc On-demand Distance Vector) is a tree based routing protocol with loop free routing. TEEN (Threshold-sensitive Energy Efficient sensor Network protocol), SPEED and MMSPEED (Multi-path Multi SPEED) are cluster based routing protocols with individual effectiveness in different performance parameters. Finally a summary of these protocols is presented with a table of different performance parameters.
无线传感器网络(WSN)是一种由具有感知、处理和无线连接能力的微型节点组成的先进传感网络。由于能力的区别，对网络的要求很高，可以对任何地理区域的物理参数进行可靠的监测和分析。由于无线传感器网络节点的资源有限，如内存短、能量有限、处理能力有限等，路由协议的设计面临许多挑战。本文从节能的角度对四种组播路由协议进行了定性研究。MAODV (Multi-cast Ad-hoc On-demand Distance Vector)是一种基于树的无环路路由协议。TEEN (Threshold-sensitive Energy Efficient sensor Network protocol)、SPEED和MMSPEED (Multi-path Multi SPEED)是基于集群的路由协议，在不同的性能参数下具有各自的有效性。最后对这些协议进行了总结，并给出了不同性能参数的表。

The use of agricultural industrial wastes to obtain value added products is an issue of utmost importance today, since solutions to problems of environmental pollution are crucial in order to achieve a sustainable development. In this respect the contribution of the so called “Renewable Raw Materials” from agricultural wastes can be a promising starting point. Further, given their provenance, these materials can be also considered as “Ecomaterials”. This issue is now considered as one of the main scientific goals at an international level, given their benign environmental impact Using waste materials avoids the expense of other often non-renewable materials, among many other benefits, with groups which are working in this philosophy called “cradle to grave” under which industries may be able to turn waste into useful materials for themselves or others, thus closing a cycle with obvious benefits. The renewable raw materials developed in our group are value added materials prepared from agricultural industrial wastes, avoiding the use of toxic substances to the environment, as well as achieving maximum economy and reduction of energy expenditure. Some of the processes developed are: immobilization of enzymes for biocatalytic processes, design of scaffolds for tissue engineering, conversion of liquid renewable raw materials into fine chemical intermediates avoiding the use of petroleum derivatives and catalysts for environmental protection.

Surface of activated carbon can be functionalized with amine groups to enhance their capacity for CO2 adsorption. Amine functionalized solid sorbents were prepared by anchoring two types of amine compounds, namely ethylenediamine (EDA) and 2-chloroethylamine hydrochloric acid (CEA) on the surface of palm shell based activated carbon (PSAC). Samples of PSAC were first oxidized by nitric acid using three different available setups to ensure about creation of a significant amount of oxygen containing groups on the surface. At the second stage, the best oxidized sample was modified by anchoring EDA and CEA on the surface to produce a superior CO2 adsorbent. Several quantitative and qualitative methods were used to characterize the prepared samples: Nitrogen adsorption at 77K, proximate and ultimate analysis and temperature programmed desorption (TPD). Moreover, CO2 adsorption study was carried out using CO2 adsorption isothermal profile at 30°C and temperature-programmed (TP) CO2 adsorption test. All modified samples had a lower surface area than the virgin PSAC. The best modified sample presented an increase of 45% in CO2 capture capacity at 100°C. On the other hand, on the basis of unit surface area, CO2 capture capacity of amine modified samples was much higher, compared to the parent sample. Furthermore, the modified samples showed a less dependency of their CO2 capacity on temperature indicating chemisorption of the adsorbate on the PSAC surface.

An advanced image processing approach integrated with communication technologies and a camera for bin level detection has been presented. The proposed system is developed to overcome the environmental situation of bin and variety of waste being thrown inside it. Gray Level Aura Matrix (GLAM) approach is proposed to extract the bin image texture. The GLAM parameter such as neighboring system is investigated to determine the best parameters values. To evaluate the performance of the system, the extracted image is trained and tested using MLP and KNN classifiers. The results have shown that the bin level classification accuracies reach acceptable performance levels for class and grade classification with rate of 98.98% and 90.19% using MLP classifier and 96.91% and 89.14% using KNN classifier, respectively. The results demonstrated that the proposed system is a robust and can work with variety of waste and various bin situations.
