    1. Polypropylene containers are autoclavable. The recommended autoclave cycle for empty containers is 121°C at 15 psi for 20 minutes. Care must be taken to allow free air circulation into and out of vessels during the autoclave cycle, especially during the venting and cooling stages. If the container is not properly vented, collapse or implosion (sometimes confused with melting) can occur. When autoclaving bottles and carboys, the cap threads must be completely disengaged from the container; the cap can be set loosely over the mouth opening at a rogue angle to ensure the threads don’t inadvertently engage. Once the container is completely cooled, the cap can be aseptically tipped into place and tightened down.

      This is virtually identical to pressure cooker conditions. Thus these tips likely apply equally to cooking. Moreover, I take this as evidence that is appropriate for cooking food in the pressure cooker, though it may warp under stresses (so stacking containers may cause warping).

    1. Take “biopolymers” for example. These naturally-derived materials are biodegradable, but they typically require the searing heat of an industrial composting facility to fully decompose. In many U.S. cities, these facilities do not exist – and placing them in the recycling bin isn’t the solution, either.
    1. we are changing all our traditional teabags into a new type of paper that is entirely plant based and fully biodegradable when placed into local authority composting.

      Oddly specific type of composting...

    1. Dictators and tyrants routinely begin their reigns and sustain their power with the deliberate and calculated destruction of art

      Art terrifies tyrants! Here's one tiny small example, but there are unfortunately hundreds of thousands examples of this.

    1. Although ostensibly inert, like Chernobyl’s ‘undead’ isotopes, plastics are in fact intensely lively, leaching endocrine-disrupting chemicals.

    1. Ecoaxis introduced industrial IoT solution for plastic processing machines which help to improve efficiency, productivity and quality. Our IoT (Internet of Things) gateway helps connect your various plastic processing machines and utilities to capture and securely transfer accurate data to the cloud for advanced analytics.

    1. Plastic time is described as unanticipated, un-reflexive and fluid, as the “experience of temporal ‘scraps’, of gapsin the schedule”, and as “the negative space of busyness”[p. 233]. Plastic time flies under the radar, being unplanned and non-immersive, and associated with neither productivi-ty nor leisure. It is interruptible, but can also expand until some other activity presents itself.

      Definition of plastic time.

      Adds nuance to the idea of digital time as plastic -- morphable in some ways. rigid in others, asynchronous but also rhythmic in its own way (especially around the examples of web surfing and TV viewing) when the experience of time is lost.

      Does plastic time also hint at kind of materiality?? Time as tangible?

    2. Accord-ingly, and in the interests of exploring how broader shifts in time use have may coevolved with digital technologies, we now look to work by Rattenbury et al. [37], which relates the always-on quality of digital technologies to more gen-eral shifts in the organization of everyday life. These are changes that have resulted in a temporal experience that they describe as plastic, a temporal experience that is both shaped by and shapes the use of digital technologies.

      Look up Rattenbury paper

      Again, seems to indicate a socio-technical temporal experience where temporal experiences influence and are influenced by digital technologies.

    1. This problem of plastic has to be solved – and quickly. This guide for kids gives a good run down and should make anyone think twice before using plastics frivolously.
