Green-speak: what does it mean?
Do you sometimes wonder what on earth the terms biodegradable, compostable, degradable, recycled, post-consumer recycled, grey-water friendly and other such terms mean? Or what the actual difference between them is?
It is easy to be confused when they are bandied about without accompanying explanation – but we hope this guide will help you understand them a bit better so you can apply them to your purchasing decisions.
Degradable / Biodegradable / Compostable
'Degradable' is a broad term given to natural and manmade substances that can be broken down by natural processes into smaller parts.
Things can be photodegradable (broken down by ultraviolet light), oxidative (broken down by thermal exposure) or biodegradable (broken down by the action of microorganisms). The term ‘degradable’ in itself does not specify any time frame in which something will break down…for instance, a large tree trunk will biodegrade over the space of many years. A tin can is degradable too; it will break down over a long period of time through oxidation, and weathering. An EPI plastic bag (regular plastic that has been treated to make it degradable), will begin to degrade after about 12-18 months, and the time it takes will depend on how much light and stress (movement) it experiences.
Biodegradable is a term given to material that, as a result the of biological activity of microorganisms (bacteria, fungi and algae), breaks down completely into the raw materials of nature (CO2 , H2O, inorganic compounds and biomass) from which it was made, and disappears into the environment.
Compostable is a term given to biodegradable materials that biodegrade within in a certain time frame under typical composting conditions (which require heat and moisture; and are consistent with the composting conditions required for other known compostable materials like cellulose).
So…when you are choosing what to buy, choose ‘compostable’ (which is therefore also biodegradable) wherever possible, or biodegradable (but not necessarily compostable) as a second choice. And remember that everything is degradable (will fall apart into smaller pieces) eventually, even if it takes a century – this term does not actually tell us much about how long the material will linger in our environment or the effect the resultant ‘smaller pieces’ might have.
Recycled / Post-consumer recycled
Recycled content in paper refers to material that has been reclaimed from the waste steam during the paper manufacturing process. Contrary to what many people think, it is not made from recycled paper waste (such as we put out with our recycling each week), but from paper factory waste (offcuts etc). Therefore, whilst it is a much better choice than non-recycled paper, it still made from tree pulp.
Post-consumer recycled content in paper refers to the portion of the material that is made from material that has been used at least once as a paper product and then recycled. This means that no trees are directly cut down to make this content of the paper, and a second great benefit is that post-consumer recycled content creates demand for waste paper (a large portion of which is still dumped in landfill as supply is larger than demand).
So…when you are choosing which paper to buy, choose the highest post-consumer recycled content you can find, or the highest recycled paper content you can find as a second choice.
Grey-water friendly
One of the best places to find independent information about what products are suitable for grey-water usage is Lanfax Laboratories – who are an independent, commercial and research organisation with special interests in soil, water and wastewater analysis. For full information on grey-water suitable products, have a good look at the Lanfax website where they test a multitude of laundry products on the resulting water quality after a test wash, and then present product results based on consideration of multiple criteria together (the combined results are what tells us whether a particular product is or is not suitable for use in grey-water).
The combined criteria Lanfax test on are:
pH: less than 8 (for liquids) and less than 10 (for powders)
sodium load less than 10gms (liquids) and less than 20gms (powders) per wash
phosphorus load less than 1 gm per wash and
electrical conductivity less than 1 dS/m per wash
If the product tests below these levels on all four criteria, then it is considered the least hazardous to plants and soil microbes. Please note that even if you are not using your laundry water on your garden and it is going into the sewer, the less treatment it needs before being non-hazardous to our waterways the better.
So…when you are choosing a laundry product, don’t just go for one that makes claims to be ‘low-sodium’ or ‘phosphate free’. Check the Lanfax Labs website to see how it rates on meeting ALL FOUR of the above criteria.

Foodswapping
Do you have…….
• lemons rotting on the ground in your backyard?
• more figs, apples, plums, olives on your trees than you can use?
• too many homegrown herbs or veggies ripening at the same time?
Would you like to meet other foodgardeners in your community? Then you could think about starting a neighborhood food swapping group!
Inspired by the success of CERES Urban Orchard project www.ceres.org.au, foodswapping groups are starting up around the country.
Why?
• To create opportunity for people to exchange otherwise-wasted fruit, veggies, herbs, seeds, seedlings
• To seed local friendships and strengthen community
• To reduce greenwaste and pressure on landfill
• To provide more healthy in-season food in the community
• To reduce the need to transport produce from outside the area, thus reducing fossil fuel use, pollution, greenhouse gases

LED lighting - the way of the futureAre you confused by the different types of lighting available? Here is a quick overview:
Incandescent bulbs (old fashioned bulbs) are very cheap to buy, however they use a high wattage of energy, and 95% of the energy they consume is lost as heat (only 5% becomes light!). They also only have a lifespan of about about 1000 hours, after which they burn out.
Halogen bulbs are basically a modified form of incandescent bulb, however halogen lamps are filled with gasses at high pressure, and operate at a very high temperature (300+ degrees). For this reason, halogens are vacuum-sealed in a glass or plastic shield to guard people/objects in case they explode. This is also why they become so hot and can be a fire-hazard when used as down lights. Typical halogen down-lights use 50 watts of energy, however are expensive to operate because you need several bulbs on one room, each of which has a lifespan of only about 2500 hours.
Compact Fluorescent Lamps (CFL’s) fit into many conventional light fittings, and have a lower wattage use than Incandescent or Halogen lamps (often about 12 watts). CFS’s have a lifespan of around 10,000 hours, however they have a charge up time of about 10 mins, during which they use about 5 times the rated wattage of the bulb, making them inefficient (energy wise) in areas where they will be frequently switched on and off.
Light Emitting Diodes (LED’s) do not use a filament like a halogen lamp does, but use a semi-conducting crystal which creates a fine band of light. By enclosing the crystal in hard plastic instead of vacuuming inside glass, a LED is a very durable lamp (can be dropped without breaking) and produces very little heat. Light from an LED down-light replacement is equivalent to about half the light of the halogen it replaces, however the energy savings are huge, with most LED down-light replacements using between 2.5-5 watts (instead of 50). We replaced our halogens with LED’s and got used to the slightly dimmer light within days. LED’s are all designed to fit straight into conventional light fittings, so you don’t need to make any changes – just take out your old bulbs, put in the LED’s and start saving energy!

All of our PLA cups and bowls, sugarcane cups, plates, and bowls, and our cornstarch cutlery are compostable in a commercial composting facility, however the process requires a certain amount of moisture and heat (which is a commercial facility is controlled to get best results).
If you will be composting at home (or school) and want to choose a cup - for example - that will break down most easily in your own compost, we would recommend the sugarcane fibre, because it is very much like paper fibre. PLA breaks down quite quickly in a commercial facility, but this is due to the high temperatures reached. If your compost is very hot, PLA should work fine. The cornstarch cutlery will take longer to break down because is it is thicker. However it is always just a matter of time…if you leave them long enough in your home compost, all of these items will eventually compost completely.
