This measuring system has a lot of unknowns, but it covers some of the main factors in evaluating a town’s process for dealing with waste. Nature has no waste and many ways of turning one entity’s waste into another’s food.
As a society, the industrial world has been characterized by an extraordinary human plunder of stored “assets” and a parallel destruction of the possiblity of growth or even survival for other forms of life.
Juan de Fuca, who is certainly not an invented character, was one of the first European visitor to the Salish Sea. He was Greek, however, from a displaced family of earlier upheavals and the Spanish never rewarded him for his explorations.
The goal of this scale is to show what an ideal, truly sustainable system for “waste” would accomplish. There are models all along the scale, but many systems (old, new and planned) fail utterly when using this scale.
1. CAPITAL COST:
Norm. $1,500 per capita. 10 points. Lose points down to $3,000 which is zero.
2. OPERATING COST.
Norm. 5% of capital costs per year.
5 points if less than 5% of capital costs.
Lose 1 point for each 1% increase above that.
3. WATER DISCHARGE QUALITY.
Norm: Better than average the population now drinks.
35 points for norm.
Some scale that takes it down down to zero for water than can only be used for irrigation.
Irrigation needs to be defined. Irrigation for human food crops? Or for pasture for cows that produce milk?
4. HEAT CAPTURE.
Norm: capture some percetage of potential available heat.
10 points for capture and reuse of at least 70% of potential available heat.
Zero if all heat wasted.
5. METHANE CAPTURE.
Same as above.
20 points for capture and reuse of at least 70% of potential available methane.
Zero if no methane captured. Although this may. Up to negative ten points if methane created and flared or allowed into atmopsphere.
Norm: everything back into the natural world.
20 points for recyling of all biosolids in a fashion that does no damage to health or the environment.
Down to zero for landfill that generates leachate.
