3. OBJECTIVES
• It helps to prevent water loss in the soil.
• Increases the water retaining capacity.
• In cold climatic regions it helps to stop the freezing of water around the roots.
• We can use it for waste water treatment to absorb all the liquid excluding solid.

4. INTRODUCTION
• Water is an essential and key component of this planet and all life that exists on it.
• When a region notes at deficiency water supply either we depend on surface or underground water for an
extended period of time due to climatic conditions.
• When a region receives constant below average rainfall for a very long time droughts are said to occur.
• With increase in water scarcity it would be beneficial to look for possible avenues to mitigate consumption of
water through a combination of good management practices and efficient technologies.

5. ABSTRACT
• Droughts are the biggest concern and todays ever growing world due to various environmental
factors such as
i)Global warming
ii)Green House Effects.
An Alternative method for water management is by altering the water holding capacity of the soils.

6. WHAT IS SAP?
• Super Absorbant Polymer (SAP) absorbs water and a release to the cultivation as
far as the soil is de-watered and increased plant performances.
• Super Absorbent Polymer(SAP) is a natural non toxic biodegradable material
• It can absorb water more than 100 times of its weight.
• It is capable to maintain the moisture of the soil and can release 95% of absorbed
water in the soil.

7. WHY SHOULD WE USE SAP?
• 1.The polyacrylate absorbent is non toxic and eco friendly material.
• 2.Its easy to use while cultivation of crops.
• 3.Increases water holding capacity,water use efficiency.
• 4.Stop soil erosion and Increases plant performance , especially in droughts
conditions.
• 5.sap enables storage of water for a month.
• 6.Superabsorbent Polymers (SAP) added into high performance concrete prevents
or reduces self-desiccation (or autogenous shrinkage) of concrete.

8. SYNTHESIS OF SAP

9. • Superabsorbent polymers are now commonly made from the polymerization of
acrylic acid blended with sodium hydroxide .
• It is done in the presence of an initiator to form a poly-acrylic acid sodium salt
• It is sometimes referred to as sodium polyacrylate.
• This polymer is the most common type of SAP made in the world today.

10. CONCLUSION
• Sap has an absorption capacity of absorbing 320gms of water per 1gm of SAP.
• So if we start using in solid waste management we can reduce waste
• It should be made available for all plants while
selling in the stores ,e-commerces.
