Sains membuka jalan ke arah ekonomi pekeliling, sifar pelepasan

Sains membuka jalan ke arah ekonomi pekeliling, sifar pelepasan

Oleh Federico Citterich

Jul 12 2023

Sebagai sebahagian daripada usaha untuk mengurangkan pemanasan global dan pencemaran, penyelidik dari University of Cambridge telah berjaya menukar karbon dioksida (CO2) dan sisa plastik dalam bahan api boleh diperbaharui dan bahan kimia berguna lain menggunakan cahaya matahari sebagai sumber tenaga tunggal.

Satu pasukan saintis dari Universiti Cambridge telah membangunkan teknologi berkuasa cahaya matahari yang menukarkan CO2 dan plastik dalam bahan api boleh diperbaharui dan produk lain yang berkenaan.

Pasukan itu, yang kajiannya diterbitkan dalam jurnal Joule, berjaya menukar CO2 kepada syngas, komponen penting bahan api mampan, dan plastik kepada asid glikolik, bahan kimia yang terdapat dalam buah dan digunakan dalam industri farmaseutikal.

Para penyelidik berharap teknologi inovatif ini akan membantu mengurangkan pemanasan global dan pencemaran dengan menurunkan tahap CO2 atmosfera dan jumlah sisa plastik.

Tambahan pula, pengeluaran bahan api boleh diperbaharui daripada CO2 boleh membantu melawan krisis tenaga hari ini dan boleh membuka jalan ke arah pembangunan ekonomi pekeliling, sifar pelepasan.

Penukaran CO2

Untuk mengurangkan tahap karbon dioksida di atmosfera, CO2 biasanya ditangkap dari udara dan disimpan di bawah tanah. Ini, bagaimanapun, mempunyai kesan jangka panjang yang tidak diketahui.

Sehubungan itu, teknik penukaran CO2 telah dibangunkan untuk mengubah karbon dioksida kepada sebatian lain.

Biasanya, kebanyakan teknik penukaran CO2 menggunakan pengoksidaan air sebagai tindak balas balas, proses yang memerlukan tenaga yang memerlukan input tenaga daripada sumber yang berbeza untuk dijalankan.

Helah dalam sistem: komponen plastik

Para penyelidik Cambridge, bagaimanapun, percaya mereka telah menemui helah yang boleh meningkatkan keperluan tenaga dengan ketara: menggunakan plastik dan bukannya air.

Vatican News bercakap dengan dua daripada penyelidik, Sayan Kar dan Motiar Rahaman, yang menjelaskan lebih lanjut mengenai proses dan matlamatnya.

“Pengoksidaan plastik membolehkan kita menggunakan tenaga suria sebagai sumber tenaga tunggal untuk keseluruhan proses, yang tidak mungkin berlaku jika air digunakan dan bukannya plastik,” jelas Motiar Rahaman dari Universiti Cambridge.

Implikasi daripada perkara ini adalah jelas: CO2 boleh ditukar kepada bahan api boleh diperbaharui tanpa memburukkan lagi jejak karbon kita.

Ke arah ekonomi pekeliling

Pasukan berharap teknologi ini boleh digunakan pada masa hadapan untuk membangunkan ekonomi pekeliling dan pelepasan sifar yang menghapuskan sepenuhnya penggunaan bahan api fosil.

“Matlamatnya adalah untuk merangka proses yang boleh menghasilkan bahan api yang boleh diperbaharui daripada sisa industri, bahan api kemudiannya akan digunakan semula oleh industri itu sendiri,” jelas Sayan Kar dari Universiti Cambridge.

“Penggunaan bahan api dalam industri tidak dapat dielakkan membawa kepada pelepasan CO2 ke udara, tetapi jika kita boleh menukar CO2 ini kembali kepada bahan api boleh diperbaharui, maka kita boleh berfikir tentang mewujudkan ekonomi pekeliling bersih sifar,” tambah Kar.

Ini juga akan melibatkan penjanaan produk berguna daripada sisa plastik, dengan tujuan mengurangkan pencemaran plastik.

Percikan optimisme

“Teknologi ini masih di peringkat awal,” kata Rahaman. “Untuk mengeksploitasi proses pada skala perindustrian, setiap komponen perlu dioptimumkan, termasuk penangkapan karbon, penyerapan tenaga suria, atau mekanisme penukaran CO2.”

Para penyelidik menganggarkan bahawa ia akan mengambil masa sekurang-kurangnya satu dekad untuk teknologi itu digunakan pada skala perindustrian.

“Kami sedang berusaha untuk meningkatkan kecekapan dan kelajuan tindak balas,” kata Kar. “Ini sudah pasti akan mengambil masa, tetapi kami yakin dan sangat optimistik.”
