“…Several studies investigated the feasibility of waste materials as a clay replacement in clay brick manufacturing. Some of them used organic wastes, such as Ghorbani et al 2021 [9] that investigated the use of potato peel powder and sour orange leaf powder in brick production. It was found that adding 7% of sour orange leaf powder decreases the compressive strength, apparent density, and thermal conductivity by 77%, 12.5%, and 76.2%, respectively.…”

The present work investigates the effect of using olive pomace bottom ash, the by-product of the clay brick industry, as an additive in the manufacture of fired clay bricks. Furthermore, it aims to improve the properties of clay bricks by using naturally available materials and also to develop an innovative way of recycling the waste resulting from the brick firing process. Olive pomace bottom ash was added to clay with multiple proportions (0%, 5%, 10%, 15%, and 20%) by weight. Bricks were molded by compression at 6.5 MPa, using a hydraulic brick press machine, and fired in an industrial scale furnace. The physicochemical, mineral, and geotechnical properties of raw materials were identified to study raw materials' effect on the final fired products' performance. The quality of fired specimens was determined by bulk density, linear shrinkage, water absorption, porosity, compressive strength, and thermal conductivity. In fact, samples with 5% olive pomace ash represent the highest compressive strength level, 11.5 MPa, compared to 9.65 MPa of reference samples. On the other hand, additions up to 20% increase the brick sample's porosity from 18.28% to 34% for the reference mixture and the brick incorporated with 20% of additive, respectively, and decrease the brick's bulk density from 1522 kg/m 3 to 1431 kg/m 3 for the reference mixture and the brick incorporated with 20% of additive, respectively. The incorporation of ash also improves the thermal conductivity of brick specimens. Expressly, thermal conductivity went from 0.41 W/m.K to 0.33 W/m.K for the reference mixture and the brick incorporated with 20% of additive, respectively, showing 37% of gain in thermal insulating properties of brick. Unfortunately, the capillary water absorption coefficient increases to 28% when 20% of additive is incorporated, which is not desired in the properties of construction materials. ASTMC67-07a standards: 2003, recommend water absorption level less than 17% for bricks with moderate weathering resistance. It was concluded that the addition of olive pomace bottom ash should not exceed 10% since it can be helpful in fired clay brick production based on standards requirements, leading to remarkable ecological gains without a loss of brick's performances.

This study aims to design a smart closed reactor of vermicomposting to convert sewage sludge and any organic waste to high-quality vermicompost. In this reactor design, all aspects of growth and reproduction of Eisenia Fetida worms, such as aeration, temperature, light, and moisture, were considered. We analyzed the physicochemical, bacterial, and microstructural of produced vermicompost and growth rate of worms in a substrate of 70% sewage sludge, 20% cow manure, and 10% sugarcane bagasse in a container and the smart reactor. The results show that vermicomposting in the smart reactor took 50% less time and 30% more worm growth rate to produce the same quality as in a container. After vermicomposting in the reactor, the parameters of pH, fecal coliform, phosphorus, organic matter, and C/N decreased whereas the parameters of carbon, nitrogen, nitrate, ammonia nitrate, and EC increased, slightly. Although, the EC amount of the reactor production is more than the container one, the amount of moisture, phosphorus, and organic matter of the vermicompost in the container is more than the reactor one.Based on the odor absorption and leachate elimination of this reactor, we recommend that it be utilized for vermicompost production, including out of smelly organic wastes such as sewage sludge, even in any public zone and personal houses.

“…The majority of landfills are filled with waste from plants, and these materials have a tendency to accumulate and cause problems with the collection of leachates from landfills. Another issue that might have repercussions on a worldwide scale is the pollution of the air that is caused by the waste products of plants [100]. A solution to this issue may be found, however, in the form of utilizing this waste material as an alternate material for the clay used in bricks [101].…”

“…In addition to this, the product, the procedure, and the route of transit all need to be validated by an environmental agency. Because of their durability and the cheap cost at which they can be manufactured, these bricks are an excellent choice for use in constructing partition walls [100]. PPP was studied by Mona et al [100], who looked at how different replacement rates (3%, 5%, and 7%) affected the soil's clay concentration.…”

This study investigates energy use in the construction sector and the potential for reducing energy consumption by improving the thermal efficiency of various building components, including walls, windows, roofs, and floors. The evaluation included a discussion on the prospects of reducing energy use. The building envelope is one of the most important factors to consider in terms of the heating and cooling energy efficiency of buildings. Walls are the fundamental component of a building's envelope and should provide thermal and acoustic comfort without compromising the aesthetic features of the building. The walls have a heat transfer area that is substantially higher than average, and the amount of heat gained or lost depends on the temperatures of the wall's inner and outside surface areas. Therefore, walls have a vital role in reducing the energy consumption of buildings. Bricks are a necessary component of highperformance thermal insulation, and lightweight bricks are especially useful in this regard. Bricks that are specifically manufactured for use in wall construction play an essential role in the management of energy consumption. The study has, as a result, provided a synopsis of the production of lightweight bricks in accordance with the source of the raw materials (e.g. Agriculture and industrial waste, etc).
