Personally I’d advise avoiding caustic use. Being a galvanizer I know that caustic soda is very harmful to the environment and is a substance only to be used when a complete knowledge of using and proper  disposal has been attained. I soak plastic in chlorine rich water for a day then sit in the high uv australian sun for a day and labels and glue come off so easily. Then put through a strip cut industrial paper shredder, this stretches the plastic loosening and dirt and ready for the final rinse , dry, and then through the pp shredder.  Cheers

Hey people, just reading through and thought I’d share what I’m doing. So first bottles get soked in a chlorine rich water. Killing all bacteria cleaning and loosening labels. Then I remove labels and rings. Then use a guillotine to cut in half and then straight into a strip cut industrial paper shredder. This makes it easier to handle and literally stretches every bit of plastic so any stubborn dirt automatically gets detached ready for a final rinse and dry. Then finally put through the precious plastics shredder. simplistically the easiest way I’ve found to clean large amounts of plastic at once. Cheers

If all that fails to accomplish what you are trying to do. Maybe look at a chain rock crusher, With a fine screen. Should turn them into powder. No more words and easily extruded plastic.

Heating up the label will make most of the glue soft enough to be removed with the label. Sign writers use this method and it works well. Hairdryer or heat gun.

I have at the moment an Ibc about one third full of water with a pool chlorine tablet in it. This over doses the water and cleans the plastic just by soaking it. I also strip shred my milk bottles for the washing process, easier to handle, clean, and dry.  I tried soaps and disinfectants, chlorine seems to be the cheapest and the longest lasting. So far I’ve cleaned about 5 months of plastic milk bottles still good. At the end I plan on filtering the water through a sand filter and reusing.

Something for you to think about, maybe even try:- rough up the plastic a little in the area to be welded then run two small grooves parallel. As the weld then goes over top. The heat will penetrate further into both pieces and create a much stronger bond. If you were to angle the groove in a different  direction this may also add or detract strength.

In the link above I think it touches broadly on this, explaining that the list of chemical additives in any given product doesn’t have to be majorly extensive. Mainly because plastics are already toxic when burnt, so the use of a hazardous material suit would be a given.  But I can totally see where you are coming from. Maybe it’ll be up to our community to leed the way, with a world wide registry of plastic additives and a simple stamp system to identify them. I’ll be adding uv stabiliser to my products and want to ensure that the next person knows what they are dealing with.

Here is a link to an in depth explanation, including how to formulate msds. or sds as we’ve started calling them. Check first your own countries regulatory authorities, but if they are not as comprehensive, put in that little bit more information. There is not a country on the planet that has this perfect, yet. Even mine. where we fall down is that we only make a few key people in our business’s responsible , safety works when everyone is involved. Gaining different perspectives will ultimately evolve the process much quicker.

I’ve had much experience with occupational health and safety and will share as much as I can so we can all get home to our families at the end of the day.
I’ll post some general msds, jsa and swms.
Just to give an idea where to start. I received an email from a company that my partner works for recently and the safety slogan at the bottom reads ” safety, it’s what we do when you are not looking “

Pleased to help and never a bother. Basically any synthetic man made items that you may have lying around from cleaning products to oils or lubricants. Looking at this very simply a main register of anything that could be dangerous when not in its intended state of rest. For example if you have some fertilizer in your business its ok just sitting there but in a fire the oxidizing chemicals in the fertilizer will make the fire burn faster and bigger because those agent’s feed the fire o2, quicker than the atmosphere surrounding the fire can do it naturally. If getting fire extinguishers for your business ensure to get powder type that will extinguish all types of fires. Hang so easily accessible and clearly marked. Anyone in countries that don’t have regulatory bodies for this kind of safety can use this model, anything can be replaced except your worker’s and friends. As for plastics don’t really have to go into detail just list the types on your msds. Any more questions please feel free to ask.

I have been thinking about this all day long it’s just how my mind works, and is just a suggestion to the entire pp community.
Dave is an inspirational leader, and I believe in my heart that project kamp is the most important thing for him to concentrate on. You just suffered through record breaking heat wave, and down under we are getting record breaking summer’s year after year. So I think  (personal opinion ) that instead of bringing everyone to you and the expense of that whole process. We the precious plastics community get together and build V4. Agree on what we want as a collective, have different people working on the process in a given time limit then bring every version together. Take the best from everyone and then the design should suit everyone, everywhere.
And by that time Dave may have jumped over the major hurdles that confront him to get Base kamp setup. I know he’s excited about v4 and I want him to be apart of it. But the sense of urgency to live sustainably has to take priority. As we need to save ourselves and the planets fragile balance of life. Please don’t get me wrong, once we’re all on that right path we the precious plastics community will still be cleaning up and restoring balance that way for generations to come.

When it comes to dimensions, everywhere and everyone may find something similar in something unexpected. Work with what suits you best . For example I am a tall person so this suits my  height. BUT PLEASE LET ME SAY AGAIN THIS IS NOT THE FINAL UNIT. I will be modifying this unit into something that will benefit the entire pp community. Everything except the pump, piping and sump was sourced from recycled materials.

I’ve tried to get a vid of the label removal process. Might be quicker just to check it out on facebook precious plastics Albury Wodonga. Below I will post some pics of the first version of my wash station. I mostly have hdpe milk bottles, and this version was mostly aimed at cleaning those. But to benefit the entire pp community I designed it so I could easily modify it. The two stage cleaning process is mostly about rinsing shredding then washing. The label removal process was just to answer a question I received. Thanks

I’ve had a similar idea all my adult life. The following is just a different perspective on your pitch for this project . We as a growing collective of intelligent , passionate and driven human beings and need your help. Our aim is to provide a template through open source, how to sustainably build a fully self sufficient community with minimal impact on the land or environment.
To accomplish this goal we are looking for land. The parameters we are looking for are….fill with what you want. But I’d suggest land that has flat and undulating qualities also. Just cause people live on all types of terrains and environments and they will be looking for answers from you long-term.
It would be awesome to meet someone who has been very successful at what they do, but just want to change their way of living. Has thought about it and realized I have too much wealth and I want to make a real difference in the world. But how?
If you are a passionate person like this come join us. Unfortunately the major hurdle we face is the land. If anyone has land you can donate to the cause please let me know. This would allow our think tank of motivated people to concentrate on the major research, building , perfection and roll out a sustainability model for everyone, everywhere.
The following is just my opinion but leave out any reference about you individually.
And what you want personally, first time I watched this I saw straight through to your goal. Others might miss interpret what you want to accomplish over you wanting to setup your own little paradise escape. Who knows you might just engage with people who have not thought about it enough.
Like I said earlier just a different perspective from the other side of the world.

I went out and got my hands on a few different strip cut paper shredders, of various sizes. Took them apart to understand the mechanisms inside. Most shredders are specifically designed for one type of material made with the cheapest parts . This means that the motors in them are barley powerful enough for their intended purpose. (Planned  obsolescence )  They also have built in duty cycles, sometimes a 5 min operation will take 20 mins to cool the heat sensors. Here are some pics of the mechanics at work inside.

If you can’t get one of those heaters, as they are expensive to source new. Here is a relatively cheaper option. Runs on butane gas. Safety note, the perforated sheet pictured has a galvanised coating. When the galvanised coating burns off, the smoke caused is a mixture of zinc aluminum and maybe even lead. If inhaled will cause what we aussie’s call gal sickness. Not pleasant at all and can effect you for days. Source non galvanised steel, I just added it for reference.

Major rivers have a lot of traffic, not only man made but also biological. But every river starts from small tributaries. This is the best place to start. I live near the beginning of the lower Murray river system. The tributaries that flow through our city have been paved over and are now classed as storm water drains. Local council has installed metal grates that are highly ineffective . Rain and major storms then use these drains and rubbish that people carelessly throw away ends up flowing through the gutters into these once natural water ways, straight into the river.
Don’t wait for anyone else, grab some friends and start cleaning up the rubbish. Start locally and share ideas with residents down river.

Here’s some pics of the filters I use in my half face respirator . You will find many different types for different applications so read carefully when buying replacements. But look at this from a different perspective build a simple extraction hood above your machines have multiple rows or  patterns with these easy attainable and easy to replace filters. The kind of fan to use would be a centrifuge for the high volume of intake through your filter system and quite running. The best part is they are made from mostly plastic. Take one apart and understand the simple construction of these. And use different ways to accomplish your goals.
Also easy to see when you need to change. In the 2nd pic notice the colour difference in the filters.

This will be one of many products that Precious Plastics Albury Wodonga will research, build, perfect and share. locally we have a green bin service that does the on a large scale. When the mounds of composting material get turned over by bull dozers or front end loaders, (speeding up the composting process) the foul smell can travel for long distances. Garbage collection of this type weekly. If this was taken care of by ourselves in our own back yard, Imagine how much safer our roads would be with less heavy vehicles running around cleaning up after us. not to mention the green house gasses those heavy vehicles produce weekly in our community.

This is the fastest and easiest solution to remove the labels I have found for myself. Heat gun or hairdryer will work also but will consume more energy and take a little longer.The day I shot this the temperature was about 6 degrees Celsius between small showers of hail and a light breeze.  The first is Hdpe milk bottle , the labels are much thinner than the containers therefore they react faster to the heat and the adhesive mostly stays on the label There are 2 layers to the label the printed information on 1 and the 2nd is the adhesive layer.The 2nd container is also hdpe, but has much thicker walls, used for chemicals. Different kind of label with only 1 layer.note the time difference.The third is Pet softdrink bottle and only has 1 strip of adhesive , and the quickest to remove. https://www.facebook.com/preciousplasticsalburywodonga/videos/531213340656055/

The whole point to the precious plastics community is education through sharing of knowledge. It gets me down sometimes with some of the negatives I see. I understand that every human being sees things from their perspective based on your own experience. But please, positivity goes so much further as it gains momentum like a snowball effect. Fact :- all synthetic man made substances are subject to out gassing that can literally last year’s after being made. Do you like that new car smell?  That’s out gassing every time you get into your new car and smell that you are breathing in those chemicals. But over time you’ve associated that smell with new, hence people admitting I love that  new car  smell. Perception. I’ve been trying hard to change my own perceptions I’m just as guilty but here are some positive suggestions. Research, if you come to a dead end share and discuss with open minds. If this fails don’t give up ask an expert in the field. There are literally panels of scientists who love information and sharing it . If they can’t answer it they usually don’t give up till their thirst for that information has been satisfactory quenched. If you are that concerned, we are humans and are very good at jumping hurdles. Air filtration systems. Plants are some of the best. Masks. We’ve all seen hazmat suits.learn love share. Dave started a movement, doesn’t mean he is all knowing and responsible for all out comes. This community is now massive and starting to evolve like one global entity. Thanks Dave for stepping out onto the road less travelled. And thanks to all the positive forward thinking people that keep us moving forward into the great unknown.

I’ve been using hill culture for the past year and is awesome. But it’s not about creating something new to fail, that’s called planned obsolescence. Unfortunately every product you buy especially new technology has planned obsolescence designed into it. That’s how our petrol dollar society was designed. It’s about introducing tried and true techniques and educating the mass population that just because some new tech or device comes out we don’t throw away the working technology we all have cause it’s not the newest. Dealing with our own waste in your own backyard instead of letting it flow down hill for the next person or generation will be better for everyone. We had so much knowledge once upon a time. People  in all different parts of the world who understood the natural world around them living in unison with nature and what did we do as a species? Slowly and surely exterminated the knowledge because on the outside there where subtle differences in their physiology where their body’s adapted to their natural surrounding environments. But in the end we are all one people, one race of human beings of planet earth. I fully admit that I was young and stupid and just as guilty but when you change your own perceptions. That’s when you start to grow as a person.

The best part about this idea is it doesn’t need power. When the bottom of the screw fills it can be turned by hand using nothing more than a gear ratio to compensate for weight. The reason it’s called a biomass composting screw is that there is a complete ecosystem of microscopic life forms living in the screw not only worms. Working together in unison , as the human race should. If you believe that we are an intelligent species, time to use that intelligence and work together and leave our animalistic tendencies in the past . It’s not the world leaders that change the world, history proves that it is the dreamers who think beyond what they are taught that have the greatest impact.

I feel v4 would benefit from a portable multi function hand held device that can join plastic sheets using a thin heated plate. While also be used as a plastic welder and heat gun. Maybe a frame to fit in the compression machine or build a slightly bigger one for rotational molding. Washing machine. Detailed air extraction unit for microfine particles. Finally a hand held extruder with the hopper attached to the roof and connected with a flexible pipe. This would be awesome from an artistic veiw.
