One of the main goals of sustainable solid waste management is to maximize the ability of its recycling and reusing. The most common waste materials are metal and plastic which are available in enormous quantities in the world. The productive use of waste material represents a means of alleviating some of the problems of solid waste management (Davis and Cornwell, 1998). Therefore, the use of this waste is very important from the environment and sustainability aspects. This leads to the saving of natural resources and resulting in a decrease in environmental pollution The waste generated during various operation and their by-product is one of the major problem arising in the world today. Plastic waste is one of the major contributing agents to polluting the environment.

The central pollution control board has estimated the generation of 15,342 tons per day of plastic waste in India. Out of which 9205 tons were reported to be recycled and leaving 6137 tons uncollected (UNEP, 2009). In landfill or in environment plastic bags take up to 1000 years to degrade. The threat due to non-biodegradable materials like waste plastics may contaminate the soil and groundwater. Disposal of the large quantity of plastic bag may cause pollution of land, water bodies, and air. Therefore, to reduce these impacts on the environment these materials can be suitably used in other industries (Hassani et al., 2005).

Brick is one of the common and widely used construction material in the world (Sudarshan and Vyas, 2017). To reduce the burden on environment brick industry, conduct a lot of experiments to utilize this waste (Singh et al., 2016). Reuse of solid waste as partial replacement of aggregate in construction activities result in reducing the demand for extraction of natural raw materials as well as saving landfill space. Thus utilization of plastic waste in brick mixes reduces the demand for natural resources and as a result, leads to sustainable development.

Normally practice of making brick in industries by vertical position during the placing of the mixture. This method was applied by press the material in mould at a certain pressure. Actually, the stress maximum of the brick is at the bottom and the top of brick while the centre of brick is the minimum value. In this study the method of placing the material in a horizontal position with the three-layer method. By using this method, the material uses at the centre of the brick can be minimized with the stress minimum at the centre.

1) Plastic bag, polybag or pouch is a type of container made of thin, flexible, plastic film, non woven fabric or plastic textile.

2) Plastic bags are used for containing and transporting goods such as foods, produce, powders, ice, magazines, chemicals and waste.

3) In this study the plastics used as sand replacement material to produce sand cement brick grade 5 N/mm² and 10 N/mm².

4) The effect of plastic to compressive strength and density of brick containing plastic compared containing river sand was identified and discuss in this paper.

5) HEB can be produced as new type of brick in construction industry as it reduce the application of sand and cement in order to produce a good quality bricks with followed requirements.

6) HEB range size 220mm x 102.5mm x 65mm

Plastic bag, polybag or pouch is a type of container made of thin, flexible, plastic film, non-woven fabric or plastic textile. Plastic bags are used for containing and transporting goods such as foods, produce, powders, ice, magazines, chemicals and waste.

About 99.5 tons of plastic waste contaminating, the coast, 31.9 million tons of plastic waste were poorly managed and estimated at 4.8 to 12.7 million tons into the marine ecosystem.

This is huge amount and with the increase in production, the use of plastics and the poor management of plastic waste, the amount of plastics entering the sea is a major threat to marine life and humans. Plastic waste mismanagement has led to several impact to human life and environment. It has been found that aquatic life and livestock has the tendency to eat plastic waste as they assume is their food source. Livestock then fall sick and eventually die, thus at the same time affect the food source of the world's population.

Due to the fact that plastic is non-biodegradable, it is essential that it is recycled as part of the global efforts to reducing plastic and other solid waste in the environment. Projection by the Department Of National Solid Waste Management Malaysia in 2012 stated that the solid waste produce by Malaysia is 25000 tons/day and 24% of it is plastic waste. Furthermore only 5% of this waste is recycle properly.

In this study the plastics used as sand replacement material to produce sand cement brick grade 5 N/mm2 and 10 N/mm2 called Hybrid Environmental Brick (HEB) The effect of plastic to compressive strength and density of brick containing plastic compared containing river sand was identified and discuss in this paper.

From results obtained is found that plastic is highly potential to be use as sand replacement material in a production of sand cement brick. Even though, compressive strength of sand cement containing plastic is lower but the properties are still satisfied to use in industry. Finally it can be conclude that the HEB can be produced as new type of brick in construction industry as it reduce the application of sand and cement in order to produce a good quality bricks with followed requirements.
