Micro-Plastic
Extremely small Pieces of plastic debris in the
environment resulting from the disposal and
breakdown of consumer products and
industrial waste.
TINY PLASTICS EQUAL BIG
PROBLEMS
Micro plastics may be tiny but they represent a less than tiny problem,
especially to marine life in the sea. When we wake up in the morning and
wash our face with a gentle exfoliating face-wash, or even when we simply
brush our teeth, we could be inadvertently washing tiny particles of
plastic down our drains. And although water gets treated at wastewater
treatment plants, these facilities generally have not been designed to filter
out micro plastics. These microbeads have been added to hundreds if not
thousands of products and with each use, these ingredients are beginning
their journey from our clean, exfoliated faces to the sea.
Micro plastic Mainly MADE OF
▪ Polyethylene (PE) .
▪ polypropylene(pp).
▪ Polyethylene terephthalate (pet).
▪ Polymethyl methacrylate (pmma).
▪ Nylon.

Consequences of micro plastics
The presence of micro plastics in the environment has a
number of negative consequences for humans and the
natural environment. If animals ingest pieces of plastic,
large or small, mistaking them for food, a permanent
feeling of satiety can result – and they starve to death.
In experiments feeding mussels with micro plastics,
researchers demonstrated that plastic particles could
penetrate the stomach lining and enter the bloodstream.
Many plastic parts contain chemicals like softeners or
flame-retardants. Some of these additives are harmful to
fertility or imitate natural hormones.
BIO-PLASTIC
Stop the production of non-biodegradable
plastics
Replace with
PHB (polyhydroxyburate)
My Opinion
PHB• PHB is produced by microorganism Bacillus megaterium.
• Microbial biosynthesis of PHB starts with the condensation of
two molecules of acetyl-CoA to give acetoacetyl-CoA which is
subsequently reduced to hydroxybutyryl-CoA.
• PHB-derived plastics are attractive because they are
compostable and derived from renewables and are bio-
degradable.
PROPERTIES
• Water-insoluble and relatively resistant to
hydrolytic degradation.
• Good oxygen permeability.
• Sinks in water
• anaerobic biodegradation
• Nontoxic.
Repair
WASTE ALREADY DRAINED TO OCEANS
The synthesis of pre organised bioinspired compounds is
advancing in order to produce functionalized
hybrid silica gels in a further step.
These gels have the ability to remove stressors such as micro
plastics from waste water.
By means of the sol-gel process, bioinspired silane compounds
can be permuted to macromolecules and examine with respect
to their properties as fixation and filter material in order to
remove the hydrophobic anthropogenic stressors sustainably.
