Abstarct: By growing the need for reduction of energy consumption to reduce the environmental pollutants as a measure of sustainable development, numerous researches have been conducted in optimal management of solid wastes in various sectors of society. In this regard, this research was to choose and examine some common, high volume waste which occupies a considerable capacity of landfills to produce brick, a widely used building material. The present study aimed at investigating the effect of adding plant residues (orange leaves and potato peels) on the physicochemical properties of brick, such as compressive strength, water absorption, dry bulk density, saturated bulk density, porosity and sound absorption is performed. To achieve the optimal properties of brick, 3, 5 and 7% weight of the brick paste was replaced with the powder of the above wastes. The moisture in the paste was adjusted to 19% while a hydraulic jack was used to exhaust the air from it. The bricks were dried in the oven prior to firing that took place in a laboratory furnace at 1100 ° C for 4 hour. Properties of soil used in bricks were investigated through X-ray diffraction (XRD). The results of the comparison of ordinary (no additives, made with the same procedure) and composite bricks (with the addition of the above wastes) showed that by increasing the percentage of orange leaf to 7%, compressive strength, dry bulk density and saturated bulk density bricks reduced to 77%, 34%, 4/6% respectively while porosity, water absorption, the percentage of soluble salts and sound insulation were increased up to 4/32% 6/51%, 21/34% and 68/13%. Also, with increasing potato peels to 7%, compressive strength, bulk density and bulk density bricks were reduced to 88%, 31%, 7% respectively and porosity, water absorption, the percentage of soluble salts and sound insulation were increased to 27%, 46%, 32/26% and 62/18 with respect to the ordinary bricks. Reducing the dead load of building and its weight, and the volume of waste plant as well as improving the sound insulation in common frequencies, along with the improved waste management are the advantages of brick made in this study. This brick is recommended to be used in parts of building where the compressive strength of the brick is not important, i.e. the bricks are used as room divider and partitions.
