Answer 1

1. Bioplastics adalah plastik yang diproduksi dari bahan-bahan yang berasal dari sumber-sumber terbarukan seperti tanaman atau mikroorganisme, berbeda dengan plastik berbasis minyak yang berasal dari fosil.
2. Bioplastik dapat membantu mengurangi masalah limbah plastik dengan menguretergantungan pada plastik berbasis minyak dan menyediakan alternatif yang lebih ramah lingkungan. Bioplastik dapat terurai secara alami dan lebih mudah didaur ulang, sehingga mengurangi jumlah limbah plastik yang berakhir di tempat pembuangan sampah atau lingkungan alam.
3. Bahan ment dapat digunakan untuk membuat bioplastik termasuk gula dari tanaman seperti tebu dan jagung, serta mikroorganisme seperti bakteri. Keuntungan dari menggunakan gula tanaman adalah bahwa mereka merupakan sumber daya terbarukan dan dapat diproduksi secara berkelanjutan. Keuntungan dari menggunakan mikroorganisme adalah bahwa merekahasilkan bahan kimia yang lebih kompleks dan berharga, seperti polimer, yang dapat digunakan untuk membuat bioplastik.
4. Dua tantangan yang disebutkan dalam artikel adalah bioplastik yang mahal dan memerlukan fasilitas khusus untuk pembuangan yang tepat, serta bioplastik yang tidak cukup tahan l digunakan. Untuk mengatasi tantangan pertama, peneliti dapat bekerja untuk mengembangkan proses produksi yang lebih efisien dan murah, serta mencari bahan baku alternatif yang lebih murah dan mudah didapat. Untuk mengatasi tantangan kedua, peneliti dapat bekerja untuk mengembangkan bioplastik yang lebih tahan lama dan tahan terhadap kondisi lingkungan yang keras, sehingga lebih praktis untuk digunakan dalam berbagai aplikasi.
