What is Waste?
‘Waste’ in relation to the utilization of material is in some senses a misnomer. The only waste that can really happen in the production of anything from material is in the gradual entropy that occurs in the transfer of energy from one form to another. That is – material is still material even if it is not used – but:
· in not using it there is an expenditure of energy that is not capable of being included in the ‘outcome.
· There is a gradual degradation /decay / disappearance of material through a process of transference from one form to another
Deciding that something (material) is not useful is not ‘waste’ unless it is not recaptured and put into another system (ie: it gets suspended in land fill)
In short – There is no such thing as “waste material” – only neglected material resources.
This “waste material” can be categorized simply in three main ways:
1. Virgin Material waste
2. Pre-consumer material waste
3. Post-consumer material waste

In each of these categories the material type can further define its capacity for being integrated into a production system. The complexity of the material and its processing systems generally increases as the material / product goes from:
virgin material - product - Pre-consumer material waste (from product manufacture) -- distribution (product to market / packaging etc) --
poiint of purchase (additional materials) --wear and tear in use-- end of life -- post consumer waste --- being mixed with other waste materials.
Dealing with waste
Sources: where do you find a reliable source – this stage requires you to think like a miner – waste material is valuable, and its scarcity can elevate its materal value. (eg. Highly recyclable materials are generally put back into the system rapidly.)
Collection:
Collecting can be difficult and the input needs to be included in the actual calculation of the value of the material.
The quantity collected needs to have some relationship to the end product value and the waste stream.
Collected material may need to be sorted (infrastructure implications)
The source and process of collection needs to have some relationship / position in the identity of the end product (ie. it becomes part of the product story)
Processing
There are over arching two ways to process materials:
1. Low Input: simple ways of either – cleaning, re-forming, recontextualizing the material in the form in which it is collected
2. High Input: returning the material to a base state so that a manufacturing process can be used to treat the material as a virgin material might be treated (ie: grinding it up into a material with no real form and forming it / Melting it down / Crushing etc)
Systems:
The systems designed and deployed are as important as the product you are designing. Without a robust set of systems for: sourcing / supply, collection, materials sorting, manufacture, distribution (taking the product to market) – you don’t really have a product to mention. In all systems there is a process of “loss” – not all material can or will be used (scrap). Energy inputs will be needed to service the systems which must be incorporated into the product cost / business planning.
So how do you do it?
You need to project the perceived value / retail price of your design and then compare that against the estimated costs incurred form your processes and systems needed to “make’ the product. You need to think of inputs: Time, cash, infrastructure, utilities, expertise etc as all having a dollar value.
If your ‘perceived value’ is less than the cost of delivering it then you need to rethink the product and the systems deployed.
The trick is to aim for minimal inputs and maximum return.
