Are They Really a Solution?

by Sarah (Steve) Mosko

Bioplastics are simply plastics derived from renewable biomass sources, like plants and microorganisms, whereas conventional plastics are synthesized from non-renewable fossil fuels, either oil or natural gas. It’s a common misconception, however, that a bioplastic necessarily breaks down better in the environment than conventional plastics.

Bioplastics are nevertheless marketed as being better for the environment, so how do they really compare?

The Problems with Petroleum-Based Plastics

The push to develop bioplastics emerges from alarming realities starting with the staggering quantity of plastics being produced, over 20 pounds a month for every U.S. resident, according to the latest numbers from the American Chemistry Council. Conventional plastics do not biodegrade (defined below) within any meaningful human timescale — they just break apart into smaller plastic fragments. This means that, except for a tiny fraction of plastic that is combusted for energy production, all plastic eventually ends up as trash, either in landfills or as litter. (more…)

  • GONE, NOT FORGOTTEN

    Since launching in 2010, we featured many inspiring writers on cutting-edge issues. In times of escalating crises, we sought to remain proactive rather than perpetually reactive, to not give more power to those who would co-opt the agenda, and to try turning visions in practice. We can critique what is and offer insights into what could be, without becoming embittered in the process. We weren't partisan, but we'll always stand on the side of those who desire peace with justice. We're not posting anymore new content as of 2017, but our archive will remain up and you can still find us on social media. We'll see you in the interwebs...
