"Kotoron" Anjing Mampu Terangi Jalan Siapa yang menyangka kotoran binatang seperti anjing, bisa menyalakan lampu jalan dan memperlihatkan kecantikan satu lokasi. Anjing pejalan kaki di Bukit Malvern, Worcestershire, menyimpan kotoran hewan peliharaan mereka di digester anaerobik, kemudian mengubahnya menjadi metana sebagai bahan bakar pada lampu.
Sebuah lampu membutuhkan 10 kantong kotoran untuk memberi lampu dua jam. Penemuan ini dilakukan Brian Harper yang memasang lampu di luar rumahnya setelah melihat alat serupa yang digunakan di Boston, Amerika.
"Saya melihat dan saya pikir ini adalah sampah. Pasti ada cara untuk mencoba mengubah kotoran pada anjing sehingga orang bisa melakukan sesuatu yang masuk akal dengan itu," katanya.
Kotoran itu dimasukkan ke dalam bio-digester yang dipecah oleh mikroba dan kemudian selama dua hari diubah menjadi bio-gas, yaitu 60 persen metana dan 40 persen karbon dioksida.
Kawasan Malvern Hills dari Outstanding Natural Beauty mendanai proyek tersebut dan Brian mengatakan kepada BBC bahwa kekacauan yang ditimbulkan anjing di perbukitan telah berkurang.
"Masyarakat memiliki tempat yang sangat masuk akal untuk menaruhnya. Mereka tidak membawa barang itu, mereka bisa melihat kotoran anjing sangat berguna dan cahaya membantu mereka jika turun dari bukit nanti malam," tutur Harper. [Metro]
