From a Metabolic Rift

Towards a Metabolic Shift

Present Human Organized Metabolism

- Open-Flow System

- Premised on Nature as Indefinite

- Exhausting its Sources of

Nourishment

- Without Paying its Bills

Could Human Beings in Politics

Reorganize Humanity in Nature

& Nature in Humanity?

Ancient Rome versus

Ancient China & Japan

Arne Backlund

Main Objectives of Sustainable Sanitation

•To Reduce Health Risks related to Sanitation,Contaminated Water and Waste

•To Prevent Pollution of Surface and Ground Water

•To Prevent Degradation of Soil Fertility

•To Optimise Closing the Loop of Human Excreted Nutrients, Organic Material and The Water Cycle Considering Energy & CO2 Balances

•Economically and Ecologically Sustainable and

Culturally Acceptable Systems

Experienced Problems From Rural Area

Work In Eastern Germany 1989 - 1993

•High Subsidies Building CWWTP

•Very High Subsidies Establishing Sewers - Up To 95 %

•Costs - Up to Euro 50000 to Connect one House

•”HOAI” 10 % of Total Cost

•Mastering the Art of Tendering

•PPP ”Betreibermodelle” & ”Kooperationsmodelle”

•Not Supporting Innovation & Visions about Ecological

& Economical Sustainable Sanitation

My Way - Innovative Production and Waste

Reducing Handling Systems in

Garnment Industri

•Karl Marx stated in Capital in 1867 on England's

Ecological Imperialism toward Ireland: "For a

century and a half England has indirectly exported

the soil of Ireland, without even allowing its

cultivators the means for replacing the

constituents of the exhausted soil.“

•Describing the Ecological Contradiction

between Nature and Capitalist society as "an

Irreparable Rift in the Interdependent Process of

Social Metabolism."

A Rift in the Metabolic Relation

between Humanity and Nature

•A Sustainable Solution to the Global Environmental Rift

requires, a Society of “Associated Producers" who can

“Govern the Human Metabolism with Nature in a Rational

Way, bringing it under their Collective Control instead of

being dominated by it as a Blind Power”.

•Solutions requires Rational Regulation of the Metabolic

Relation of Human Beings to Nature in line with the Needs

of Future Generations. "Even an entire society, a nation, or

all simultaneously existing societies taken together," Marx

stated, "are not owners of the earth. They are simply its

possessors, its beneficiaries, and have to bequeath it in an

improved state to succeeding generations as boni patres

familias [good heads of the household].

Tentative Holistic Reflection

•We Can´t Solve Problems by Using More of

the Same Kind of Thinking (Paradigm) we Used

Creating Them!

•Conventional Waste Water Solution – with

Mixing & Dilution – Best Solution to Polution?

•Why do Human Beings with Two Outlets

Design and Use Toilets with Only One Inlet?

•When the Solution is Simple,

God is Answering!

Flow or Stream of Material

•Human urine contributes to about

80 % of the load of N and 50 % of

the P load of conventional domestic

wastewater

•Human Urine treated conventional

requires large amounts of energy

producing problematic sludge

Flow or Stream of Materials

•We Excrete most of the Nutrients we

Consume

•Human Urine contributes with only 1

% of the Volume of Household

Wastewater but contains 80 % of N, 55

% of P and 60 % of K and less than 0.6

% of Cadmium and 0.06 % of Lead

Phosphorus

•One Person Excrete 1 KG P/year.

•0.7 KG in Urine and 0.3 KG in Faeces.

•Human Phosphorus Returned to Soil

Would Cover 80 % of P Demand

•In Agriculture Short of Phosphorus

Human Excreta could be a Golden

Opportunity.

•In 100 years Phosphorus Could Be Gone.

A Way Out

New Paradigm of Closing The Loop With Alternative Sanitation

•Alternative Questions and Answers

•Different Streams and Flows

•Source Control

•Nutrients, Organic Material, Water etc.

•Diversion and Concentrated Collection

•Reuse of Resources to Plant Growth

•Re-Defining

•Re-Designing

Alternative Approach and Design

•Human Urine (Yellow Water or

Golden High Quality Anthropogenic

Nutrient Solution) and Human Faeces

•Diverted and Concentrated Collection

•Waterless or Reduced Water Flush

•Alternative Sanitary Components

•Alternative Sanitary Systems

Alternatives in Recycling

Nutrients and Water

•Nutrients Directly From Toilet

•Direct Local Use or After Transport

•Household Wastewater Directly into

Willow Evapotranspiration System

•Transported Septic Sludge

•Wastewater and Sludge from CWWTP

Selected Components

•Waterless Urinals

•No-Mix/Diverting Toilet Stools

•Vacuum Toilet Systems

Composting - Organic residuals and harvested willow are

composted

Closing the loop - By taking human urine and compost back to

agriculture based on permaculture principles.

application to EWSRP

•Reduces Demand for Chemical Fertilizers

•By far Most Important Public or Private Cost

Reduction - Allocating Nutrient Removal to EWSRP

•Cost kg N Conventional N-Removal Often 10 Times
