The plastic waste is the hazardous problem in today’s world. This is most dangerous problem in front of society. The most hazardous type of wastes are HDPE and PTE and the plastic below 50 micron is also causing a serious problem like plastics wastes, non degradable, environmental pollution. These plastic mixed in the soil, it directly effects on fertility of the soil. Nowadays, the large amount of plastic is deposited into sea. This plastic wastes gives hazardous effect on the aquatic life and quality of seawater also polluted by this plastic. By recycling and reuse we try to find efficient way to solve this problem of plastic waste. So by various test trials in the project we added this plastic wastes into the bricks and create the bricks by using plastic wastes. It is most economical solution present in the construction industry and it is also economical and environment friendly solution of the plastic wastes. Plastic brick is another type of brick which can be made from the plastic waste. This bricks are the solution of the pollution from the waste plastic. This bricks are easy to make and the pollution from the brick kilns can also be stopped using these bricks as there is no requirement further for the brick kilns. This brick have more strength than normal bricks and having light weight which can give further benefits to sustainable structures In our project we are making bricks by using waste recycled plastic due to shortage of cement. Waste plastics are widely available in all areas. We are using recycled PET bottles, carry bags, HDPE, LDPE and to make plastic bricks. Primarily recycled plastic PET bottles, carry bags, HDPE, LDPE was collected in nearly areas. It was converted into grains.A handmade wooden mould is taken and the mixture was poured in that and compacted. It is allowed to dry for a period of 24 hours. The curing period was 7 days and 28 days. By this process plastic bricks are obtained and it is compared with conventional bricks. To check its properties several tests were conducted. They were Compression test, Water absorption Test, Efflorescence test, Hardness test and Soundness test. Plastics which are used in our day to day life are 1. (PP) Polypropylene 2. (HDPE) High density polythene 3. (LDPE) Low density polythene Above plastics are the plastics which are used in our day to day life and due to this big amount of scrap waste gets in environment which cannot be decompose and nor can be destroyed so we try to put it to use in most efficient way possible.
Plastic is the very hazardous material and very difficult to decompose it is main problem in the world. Use of plastic is high in our daily life such as polythene bags, disposals, furniture’s, packing food packets and other accessories. Plastic is very in large and various types according to their chemical composition. So, to separation of plastic wastes and mainly big problem in front of us. Nowadays, In the world plastic deposited by burning procedure. They emit large amount of hazardous and toxic gases. These gases effect on the human health and also living animals. Human suffers by the toxic gases such as cancer, high blood pressure, Asthma. etc We are not completely able to stop the use of plastic but we are able to recycle and reuse it by many ways and minimum effect on environment. We use such recycle plastic in the various industries such as construction, transportation, manufacturing. etc. In construction industry, larger cost of project is include in materials up to 60% to 70% of the total cost of the project. So, construction industry large amount of bricks are used and they available in various forms such as clay bricks, concrete bricks, fly ash bricks and foam bricks. In this project, we try to use wastes plastic to manufacture the bricks and increase the strength. Plastic is one of the daily increasing useful as well as hazardous materials. At the time of need plastic is found to be very useful, but after its use, it simply thrown away, creating all kind of hazards. Plastic is non-biodegradable, so it will continue to be hazardous for centuries.
The idea of this paper is to use the Waste Plastic as a Building Materials such as Bricks. So as to reduce the Plastic Waste and Save the natural resources like Yamuna which is degrading due to Waste Plastic. As more the cities become industrialized surplus problem of the plastic waste management comes along with it. Technological and economic advancement has made the type and kind of plastic very diverse and their management much more complex. The Outbreak of disease like cholera, diarrhea etc. is becoming more due to this waste Plastic. Furthermore the changing economic trends and rapid urbanization disarrange plastic waste management in developing countries. Also various tests we are going to perform on bricks like

IV. PROCESS OF MAKING PLASTIC GRAINS
V. SELECTED POLYMER GRAINS
A. HDPE (High Density Polythene)
High Density Poly Ethylene (HDPE) is a thermoplastic polymer made petroleum. AS one of the most versatile plastic materials around ,HDPE plastic is used in a wide variety of applications, including plastic bottles ,milk jugs , shampoo bottles , bleach bottles, cutting boards, and piping . Known for its outstanding tensile strength and large strength to density ratio, HDPE plastic has a high impact resistance and melting point.
Beside its use foe food applications, it can be found in unusual places, including:
High-density polyethylene, or HDPE, is a type of plastic that’s tougher and stronger and can endure higher temperatures than most other polymers. This durable plastic is used in a wide variety of applications, from transporting water to storing school books while students are in class. But those who aren’t familiar with this versatile material or who have had negative experiences with other materials in the past might be concerned about the product’s safety.
B. LDPE (Low Density Polyethylene)
Low density polyethylene (LDPE) is a thermoplastic made from the monomer ethylene . It was first grade of polyethylene , produce in 1933 by Imperial Chemical industries (ICI)using a high pressure via free radical polymerization. Its manufacture employs the same method today. LDPE’s lower density and branched molecules give it somewhat different properties than HDPE, although they do share some similar uses, such as packaging. LDPE/HDPE differences typically cause them to be collected separately for recycling … but not always LDPE is resistant to impact (doesn’t break easily), moisture (water proof), and chemicals (can stand up to many hazardous materials). What happens to all that LDPE collected for recycling? When recycled, LDPE is given a second chance to live on as other useful products, such as:
(PP) also known as polypropylene is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene . Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar. Its properties are similar to polyethylene, but it is slightly harder and more heat resistant. It is white, mechanically rugged material and has a high chemical resistance. Polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene. Polypropylene belongs to the group of polyolefins and is partially crystalline.
PP has become a material of choice, especially when you are looking for a polymer with superior strength (e.g., vs Polyamide) in engineering applications or simply looking for cost advantage in blow molding bottles (vs. PET).
Depending how it is produced and formulated, polypropylene can be:
VI. PROCESS FOR MAKING POLYMER BRICKS
1) Waste plastic, which is available everywhere, may be put to an effective use in brick making Plastic bricks can help reduce the environmental pollution, thereby making the environment clean and healthy. 2) Plastic bricks give an alternative option of bricks to the customers. 3) Local people of these areas will be free from the hazardous issues of waste around them and this brick will be used for redesigning their houses which used to get washed away in the monsoon season. 4) This project is an innovative and new idea in itself because it deals with the problem at a very macro level but solves it in a very micro perspective view. 5) This project can be further implemented in the other parts of the world after its success in india. 6) We conclude that the plastic sand bricks are useful for the construction industry when we compare with Fly Ash bricks and polymer brick.
