Evaluation of Waste Cooking Oil as Sustainable Binder for Building Blocks

Abstract

Increasing depletion of material resources and concern for the environment has led to the great quest for degradable and environmentally sustainable material in various industries in recent years. Application of Waste Vegetable oils as a renewable and biodegradable binder material was explored in this work. Block samples were prepared with 10% liquid binder of vegetable oil, compacted with 75 impact blows and thermally cured in a conventional oven at temperature ranges of 160-200°C. This study explores the effectiveness of waste cooking oil as a novel binder in the production of building block, called WasteVege block. Important parameters such as optimum binder content, optimum curing temperature, and optimum curing age were established. The mechanical and physical properties of the product were examined, the result shows that compressive strength in ranges of 5 - 34 MPa was achieved, initial rate of absorption (IRA), water absorption, efflorescence, and wet/dry durability of the product exhibit acceptable values within the threshold of required standards.

Assessment of the Environmental Impact of Solid Oil Materials Based on Pyrolysis Oil

“…Based on the results obtained from the dependence of the applied standard force on the strain of the specimen, it can be concluded that the higher the annealing temperature of the oil blocks, the higher the strength of the material. For comparison, blocks based on waste cooking oil obtained at 170 • C had a compressive strength of about 34 MPa and stiffness of almost 20.16 MPa, while blocks obtained at 200 • C had the lowest values of these parameters due to high porosity [25]. Oil blocks obtained by the polymerization of waste cooking oil in the presence of an acid catalyst differed in mechanical strength depending on the process parameters in which they were obtained.…”

“…Attempts have been made to create unconventional building materials based on waste oils. The literature has mainly focused on vegetable waste oils from the thermal processing of food [24][25][26]. No data were found on the acquisition of oil blocks based on post-pyrolysis oil; therefore, an attempt was made in this work to produce solid composite materials (oil blocks) based on pyrolysis oil.…”

Preparation and Characterization of Polyurethane Rigid Foam Nanocomposites from Used Cooking Oil and Perlite

“…In particular, at treatment plants, a thin impermeable layer is formed, which prevents the exchange of gaseous with air that results in increasing wastewater pollution indicators (Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS)), and a reduction of the efficiency of pumps and filters at the station [9,10]. The recent increase in the number of publications and patents underlines the enormous potential that UCO (when recycling) goes beyond its use only in the production of biofuels, as it can be used as value-added green chemicals such as surfactants [11,12], binders for building blocks [13], plasticizers [14,15], lubricants [16], and biopolymers [17]. Environmentally being polyols, which naming as biopolymers, can be obtained from either transesterification of oils or ring-opening of epoxidized oils processes by using a wide range of reactive materials such as alcohols in wide ranges of hydroxyl numbers as well functionalities and viscosities [18].…”

Effect of Waste Cooking Oil-Based Composite Materials on Radish Growth and Biochemical Responses

“…Vegeblocks were cured at 160-170 • C for 12-48 h. An increase in mechanical strength was observed when the annealing time was extended beyond 24 h. In addition, it was shown that the material does not pose a fire hazard and does not ignite when exposed to 500 • C for 2 h [18]. Adebayo et al [19] obtained a polymer binding material from vegetable oils. The composite materials were formed by annealing a mixture of sand and waste cooking oil at 160 to 200 • C, and their compressive strength was up to 34 MPa.…”
