“…Therefore, the petrochemically derived, non-degradable and toxic plastic materials can be replaced by ecofriendly materials derived from biomass. A brief and comprehensive comparison between the properties of plastics and bioplastics is given in Table 8 [125][126][127][128][129][130][131][132][133][134].…”

Degradation of Plastics

Plastics are polymers of long chain hydrocarbons based on petrochemicals. Due to their physiochemical properties these are almost non-degradable and their complete recycling is impossible. High production rate and less disposal capacities have made plastic environmental pollutant resulting in severe impacts on the health of organisms and destruction of habitats thus effecting the biosphere in different ways. Biodegradation, thermal and catalytic degradation of plastics is widely studied to ensure a sustainable disposal of plastic waste with limited results until the present however, a new field where ecofriendly polymers obtained from natural biomass are used to make materials is flourishing. Bioplastics are polymers derived from biomass such as cellulose, starch, chitin and microbial polyhydroxyalkanoates that have the ability to produce products of daily use that can replace their counter parts made from the synthetic plastics. Bioplastics degrade easily in natural environment and replace the petrochemical based plastic polymers, thus saving the natural environment from plastic pollution and ensuring a sustainable environment.

“…Beberapa tahun terakhir penggunaan bioplastik meningkat. Bioplastik dipandang ramah lingkungan karena dapat terurai kembali menjadi CO2 (Sidek et al 2019). Saat ini, kelestarian lingkungan sudah menjadi komitmen sebagian besar industri.…”

“…Namun, kelemahan bioplastik pada umumnya adalah bersifat hidrofilik sehingga mudah rusak bila terkena air. Selulosa yang tidak larut dalam air dapat dipakai sebagai penguat bioplastik sehingga tahan terhadap air (Silviana dan Pudjirahayu 2017), contohnya plastik film, kemasan, dan alat kesehatan (Sidek et al 2019). Kristal selulosa dengan ukuran nano merupakan bahan nanokomposit kinerja tinggi yang menghasilkan produk inovasi diberbagai bidang seperti teknik biomedis, ilmu material, elektronik, dan katalisis (George and Sabapathi 2015).…”

EKSTRAKSI DAN KARAKTERISASI MIKROSELULOSA DARI RUMPUT LAUT COKLAT SARGASSUM SP. SEBAGAI BAHAN PENGUAT BIOPLASTIK FILM. Sargassum sp. merupakan rumput laut coklat yang banyak tumbuh disepanjang pantai Indonesia. Tujuan dari penelitian ini adalah mengekstraksi mikroselulosa dari rumput laut coklat Sargassum sp. yang diambil dipantai daerah Banten. Selulosa dan mikroselulosa diekstraksi melalui dua tahapan yaitu proses alkalinisasi dengan kalium hidroksida (KOH) dan dilanjutkan proses hidrolisis dengan asam sulfat (H2SO4). Variable konsentrasi optimal KOH untuk menghasilkan selulosa adalah 0,1%, 0,7% dan 1,3% (b/v), dengan karakterisasi gugus fungsi produk menggunakan Fourier-Transform Infra Red (FTIR). Hasilnya menunjukkan bahwa pola spektrum FTIR selulosa dengan alkalinisasi pada konsentrasi KOH 0,1% dan 0,7%, (b/v) berbeda dengan pola spektrum selulosa dengan konsentrasi KOH 1,3% b/v Optimalisasi proses hidrolisis untuk menghasilkan mikroselulosa dilakukan dalam H2SO4 1 M dengan variabel kecepatan pengadukan 1000 rpm, 1500 rpm, dan 2000 rpm serta variabel waktu proses 30 menit dan 90 menit. Spektrum FTIR mikroselulosa dari semua variabel menunjukkan pola yang sama. Bentuk permukaan selulosa hasil foto Scanning Electron Microscope (SEM) dengan pembesaran 100.000 kali terlihat seperti bulatan, sedangkan mikroselulosa berbentuk garis panjang. Penambahan mikroselulosa pada bioplastik pati tapioka/kitosan menghasilkan bioplastik yang lebih tahan terhadap air dibuktikan dengan sisa bioplastik lebih panjang dibanding blanko setelah direndam selama 8 hari.

“…Furthermore, the plastic recycling process is quite challenging, as different plastics require different recycling techniques. Only around 10% of the total plastic manufactured every year is recycled, with the rest dumped into the water bodies and landfills [1,2]. The indigenous microorganisms do not have inherent potential to degrade these plastic wastes.…”

Plastic has become one of the most crucial requirements of the modern-day living. The continuous reliance on the petroleum-based, non-biodegradable plastics has resulted in increased global environmental damage and rapid depletion of fossil fuels. Bioplastic, with remarkably similar properties to petroleum-based plastics is a promising alternative to overcome these emerging challenges. Despite the fact that algae and cyanobacteria are feasible alternative source for bio-plastic, there have been limited studies on strain selection and optimization of culture conditions for the bio plastic production. Naturally, algae and cynobacteria can accumulate higher amount of metabolites under stress conditions however one of the recent study on genetic engineering of Synechocystis sp. coupled with abiotic stresses showed up to 81% of increase in PHB level in the transformed lines. This chapter provides summary of various studies done in the field of algal bio-plastics, including bioplastic properties, genetic engineering, current regulatory framework and future prospects of bioplastic. Further the applications of bioplastics in industrial sector as well as opportunities and role of bio plastic in green economy are also discussed.
