Bio-based drop-in chemicals are bio-based versions of existing petrochemicals which have established markets. Bio-based drop-in chemicals usually differ from their petrochemical counterparts in price (mostly more expensive)and in environmental footprint (mostly lower).Regarding the ease of implementation, bio-based drop-in chemicals are easy to implement technically, as existing infrastructure can be used. However, due to their usually higher price compared to their fossil counterparts they are often not competitive. The drop-in bioplastics are more expensive than the original fossil based plastics, this may be due to Economy of scale, R&D and Price of raw material

Oceans are polluted through plastic debris ranging in length from huge unique cloth consisting of bottles and bags, right all the way down to microplastics formed from the fragmentation of plastic cloth. This cloth is simplest very slowly degraded or eliminated from the sea so plastic debris are now extensive during the floor ocean and are recognised to be having deleterious consequences on marine life. At least 14 million lots of plastic emerge as within the ocean each year from floor waters to surface of oceans. Thousands of seabirds and sea turtles, seals and different marine mammals are killed every yr after consuming plastic or getting entangled in it. When merchandise or substances are marine degradable, this indicates they may disintegrate (bodily smash down) into portions smaller than 2mm in simply three months, and can be absolutely biodegraded (chemically damaged right all the way down to harmless factors and compounds) in beneath 6 months. This makes those substances a great deal much less possibly to damage marine wildlife
