This document discusses biodegradable materials and measuring their degradation rates. It explores using biodegradable plastic bags, chairs, drinks bottles, and cans to help the environment. An activity measured the degradation of foam peanuts, gelatin capsules, films and gels in acid, base and boiling water. All biodegradable materials degraded fastest in boiling water, and acidic solutions caused faster degradation than basic solutions. The document also proposes using bioplastic pipes for irrigation to water soil periodically without landowners, apply in gardens and homes, provide a cheap product, and help save money for state farms by acting as compost.

3. Introduction

5. Hunting for Biodegradable objects
Should be
Biodegradable
Reasons Should not be
Biodegradable
reasons
Plastic bags It being using a lot , to
help environment and
decrease polliotion .
Chairs Because it will
degrade in wet
weather .
Drinks bottles
or cans
Because it used daily
by enormous amount
, to reduse garbage.
cars Because we buy it
with a lot of money so
it will be a waste to
lose it , it will degrade
in raining .

7. ACTIVITY 4 : measuring the
degradation rates of Biodegradable
Materials
We measured the degradation rates of different Biodegradable
Materials in different solutions
HCL 0.0001 m NaOH 0.0001 m Boiling water
FOAM PEANUT 5:45 7:55 7 sec
GELATINE CAPSULE 5:47 8:50 19 sec
5% FILM 1:56 2:35 2 sec
20% GEL 3:42 5:35 8 sec
CONCLUSION : ALL Biodegradable Materials DEGRADE FAST IN BOILING WATER , AND
IT DERADE IN ACIDIC SOLUTIONS FASTER THAN BASE SOLUTIONS .

14. 1-water the soil periodically without the need of
land or farms owners to be available.
2-you can apply it for gardens at homes and farms.
3-this product is cheap.
4-Also it will help to save money if it applied in
State farms.
5-The bioplastic will be a compost for the soil.
