“…Physical analysis and determination of exact waste materials compositions are key factors in designing a management strategy in terms of considering recycling, reuse, transformations and final disposal (Aparcana, 2017; Park, 2014). In the case of ISW, manufacturing technology and extent of reuse and recycling directly affect the compositions of generated waste materials (Adazabra et al, 2017; Thomanetz, 2012). As shown in Figure 4, the major components of waste materials generated in the Savojbolagh industrial zone were as follows: plastic (28% w), which was comprised of 1.81 t d -1 ; different types of plastic, paper and cardboard (22% w), which was comprised of 1.45 t d -1 ; and metals (15% w), which was consisted of 1.329 t d -1 different ferrous and non-ferrous metals.…”

The main objective of this research was to investigate the waste characteristics and management activities in the Savojbolagh industrial zone, Iran, in order to rank the active industries from environmental perspectives using an innovative index. First, the industrial categories with over 50 employees were identified and classified according to their production process. Then, 54 industries were selected and all industrial processes, the types and quantities of products, per capita industrial waste generation, physical analysis and management activities in terms of minimisation, storage, processing, recycling and disposal were evaluated. The required data were obtained through questioners, interviews and field observations. A scoring system was prepared for evaluation of environmental status of waste management practices. Results indicated that the total industrial waste generation rate was 67,258 kg d-1, in which 4528 belonged to hazardous waste. Furthermore, the per capita waste generation rate was 5.51 kg d-1. Plastic, paper and cardboard and metals constituted the most fractions of wastes, respectively. Food and beverage, metallic and chemical/plastic industries were the biggest waste generators. Metallic industries with total score of 502.5 and non-metalic-mineral industries with the total score of 114 were categorised as the best and worst industries in terms of waste management practices.

“…However, agricultural biomass additives such as straw improve the properties of mud bricks [1].Consequently, studying these properties is a first step in evaluating the impact of the material not only on energy consumption, but also on indoor comfort [3]. The use of organic additives has increased worldwide, mainly due to their availability and also for their thermal, mechanical and environmental impact [4][5][6][7][8][9][10].As a result, the incorporation of biomass additives into clay bricks can reduce thermal conductivity and enhance compressive strengths. In our case, we used the argan shells as additives to the clay blocks; Argan trees are located mainly in the sous massa region.…”

This research investigated the impact of agricultural biomass additives (Argan shell) on the thermal and physical properties of fired clay bricks for building application. The objective of the study is to characterize the selected materials from molecule up to the final materials used in buildings. The materials used in this study, are soil and Argan shells, locally available materials for brick making. The Argan shells were grinded and then added to the clay mixture. The Clay brick shows a formation of pores during the firing process up to 1050°C. As results, the bulk density of the clay bricks decreased due to the pores formation. On the other hand, the thermal conductivity of the clay bricks was reduced by 53% using 20wt% of the biomass additives.

“…Currently, incorporating waste as building material is getting importance and benefiting construction sector by improving the functional properties. Recycling of various waste materials like corn cub, rice husk, wine waste, glass powder, marble powder, shea waste, fly ash, ciggerate buds, granite waste, sugarcane baggage [7][8][9][10][11][12][13][14][15] were utilised in manufacturing of bricks. Each additive has its own process and functional advantages like light weight, increased water absorption and energy efficient.…”

The disposal and waste management of solid high energy propellant (HEP) is a considerate conservational problem. HEP waste is currently disposed in open or confined burning which may cause environmental hazards. In this paper, we examined and discussed results on recycling of HEP waste into fired clay bricks baked in different orientation. HEP modified bricks with 1.5%, 3% and 5 wt. % HEP waste content were manufactured and tested, and then compared against virgin clay bricks without HEP content. The effect of directional orientation of bricks baked with varying HEP content on acoustic properties were experimented and discussed. The sound transmission loss decreases with increase in HEP waste due to formation of independently closed directional pores. The transmission loss of horizontally baked during firing of bricks is nearly 5dB lower than vertically baked bricks. Results of the experimental studies indicate that HEP waste can be utilised in fired clay bricks and different orientation baking further enhances the acoustic properties.
