ABSTRACT Each year‚ the oil industry generates millions of barrels of wastes that need to be properly managed. For many years‚ most oil field wastes were disposed of at a significant cost. However‚ over the past decade‚ the industry has developed many processes and technologies to minimize the generation of wastes and to more safely and economically dispose of the waste that is generated. Many companies follow a three-tiered waste management approach. First‚ companies try to minimize waste generation

1. INTRODUCTION 1.1 GENERAL Water recycling or the reuse of treated wastewater is becoming a necessity in today’s world. Under constant threat due to climate change‚ explosive population growth‚ and wastage‚ there is tremendous pressure on water‚ a basic and valuable resource. While industrial growth and unplanned water utilization for agricultural use have depleted ground water levels in many parts of India‚ the growth of urban clusters have brought pressure on available water.

Landfill gas is generated during the decomposition of organic substances in municipal and industrial wastes. Since it is made up of powerful greenhouse gases‚ primarily methane gas and carbon dioxide‚ the prevention of escape to atmosphere is desirable and has the added benefit of being utilised as a renewable energy source (Clarke Energy‚ 2014). One such company focussed on dealing with this issue is Landfill Gas Industries Pty Ltd (L.G.I. Pty Ltd) they are ‘a specialist designer‚ supplier‚ installer
