The term biochemical can refer to any chemical compound which is part of the makeup of living cells. Biopolymers are ecologically safe alternatives to polymers due to their biodegradability and their origin from renewable resources. he natural polymers refers to macromolecules that occurred naturally or synthesized by living organisms. Biopolymer is widely designated for biodegradable polymer or biobased polymers whether natural or synthetic. Recent discoveries in the field of bacterial polymer biosynthesis have opened up new avenues for the rational engineering of bacteria towards the production of biopolymers suitable for industrial and medical applications. Selection of a suitable composition substrate is an important factor for the optimization of biopolymers production and properties. Since, the high cost of substrates is a major factor in biopolymers production economics, thus the usage of waste biomass could significantly reduce the total production cost.
Investment in biochemicals and biopolymer production capacity is starting to increase from a very low base. Rapid technical progress is also being made in regions such as the US, Asia and Brazil, with a particular focus on facilities using readily available sugar and starch feedstocks.
The global chemistry market was estimated at the € 3127 billion in 2012 and to $4012 billion by 2020. In 2014, the European chemical industry made a market of €673 billion, of which € 558 billion in the European Union. There are several bio-based products on the market and in the EU. In 2011, the chemical industry has used about 8.6 million tonnes of renewable raw materials (Cefic, 2014). The renewable raw materials include vegetable oils and animal fats, carbohydrates, sugar and starch, natural rubber, etc.
The sales of chemicals based on industrial biotechnology were estimated at around € 135–150 billion Euro in 2012 (9% of chemical market) and to € 515 billion until 2020. The percentage of products derived from biotechnological processes will increase in all market segments: base chemicals will increase from € 16 billion in 2010 to € 71 billion in 2020, polymers and fibers will increase from € 19 billion to €167 billion, specialty chemicals will reach €89 billion from € 22 billion, consumer chemicals will grow from € 18 billion to € 104 billion and active pharma ingredients from € 16 billion to € 83 billion. The share of biochemicals was estimated to be 3.5% in the case of biobased products, 9% in the case of specialty chemicals, 12% for consumer chemicals and 34% for active pharma ingredients. For the EU, it was estimated that up to 30% of oil-based chemicals and materials would be replaced with bio-based ones by 2030 (Scarlat et al, 2015).
