Re: [greenlifestyle] Kemasan Hoka2 Bento dari styrofoam

Tentang Pampers dan Pembalut,

sebetulnya ada yg ngga sekali pakai, jadi bisa dan mudah dicuci. Biasanya untuk orang yg allergi. Harganya memang mahal tapi karena untuk pemakaian jangka panjang ya hitungannya jadi murah.

Produk ramah lingkungan dalam arti yang sebenarnya kan seperti itu. Mahal karena produknya organis bukan produk dengan berbagai gel yang membuat bayi gatal2. Selain itu mahal karena belum diproduksi masal.
Tapi kalo mau itung beneran (harga mahal : lama pemakaian) , jatuhnya malah murah.

Susah juga pak, sebenarnya kita sendiri juga butuh plastik. Yang diperlukan adalah material pengganti plastik yang memiliki kekuatan ikatan unsur yang setara dengan plastik namun ramah lingkungan. Styrofoam dan Plastik sama2 mengkhawatirkan. Salah satu sampah yang jadi masalah juga sampah pampers dan pembalut yang justru berbahaya karena kandungan biologisnya. Apakah pemecahannya yang ideal?

Dear kawan2,
Informasi ilmiah mutakhir ini semakin meyakinkan kita bahwa gerakan anti plastik harus makin digalakkan. Setiap org harus mulai risau / semakin merasa bersalah menggunakan dan membuang plastik yang nyata-nyata meracuni planet. Ketergantungan akan plastik harus terus digugat dengan semangat yang makin militan.

Bayangkan, sdh muncul sekelompok orang yang berjuang untuk 'melegalkan ganja' karena alasan2 yang ilmiah, katanya. .

Jadi untuk plastik, mari kita tidak kurang militannya berjuang mengurangi konsumsi plastik, sampai akhirnya masyarakat kita bebas plastik !

Ayo siapa akan mulai ?

Salam,
Bintang.

Dapat terurai setelah penggunaan (dg wkt yg lama) bukan berarti aman saat memanfaatkannya!...

Beberapa hari y.l., Ibu Yuyun kirim link yang sangat menarik ke artikel di majalah "Nature" mengenai aditif yang bikin plastik cepat terurai.


"Eco-friendly plastics memang bisa terurai tapi prosesnya sangat lama dan lambat. Tidak bisa dicampur dengan komposting karena akan mengacaukan hasil dan proses kompos Kesimpulan scientists: oxo-degradable plastics itu gak ada manfaatnya buat lingkungan... "
 
Eco-friendly plastics disintegrate, but might just linger in the environment.
Although it is clear that 'degradable' plastic bags, for example, will fall apart in the environment, the resulting fragments can persist for a long time, and there are no long-term studies on these pieces. A key issue is that products can be described as biodegradable without reference to the timescale it takes them to fully biodegrade.

"There are a tremendous number of papers about degradable polyethylene but no one has really shown a high degradation," says Ann-Christine Albertsson, a polymer researcher at the Swedish Royal Institute of Technology (KTH) in Stockholm and lead author on the critical review. "Of course they degrade in one way – they are losing part of their properties. But if you mean it as a positive for nature, that has not been proved."

The Defra report suggests that oxo-degradable fragments left outside in the United Kingdom would become small fragments over two to five years. The biodegradation of these small fragments then proceeds "very slowly", it notes.

These plastics should not be composted, as their breakdown fragments will ruin the resulting compost.

"Our conclusion was there is no benefit to the environment of oxo-degradable plastics," Thomas told Nature.
