MY IDEA OF PARADISE ON EARTH


2

Did you know that…•We all leave behind – in our homes, at work, on travel, in leisure activities – renewable organic material (ROM) in residues and waste

• ROM originates from plant and animal kingdom - can be used for production of many valuable products by biorefinery

• Biorefinery is conversion processes and equipment to produce value-added chemicals from ROM

ORGANIC WASTE TO BIOENERGY AND BIOFERTILIZERS

Each individual in the Western countries create at least 2 kg Renewable Organic Material (ROM) per

day • liquid as toilet waste (urine and faeces without

water) and • wet or dry in household waste

The mixture can be used as a feedstock for the production of

biogas and biofertilizers in local biogas plants

How to get paradise on Earth?

With help of biotechnology – by biological conversion of renewable organic material in residues and waste by microorganisms

•when bioenergy is used efficiently •plant nutrients are returned to the fields

That will increase soil fertility promote production of safe food

while pollution and costs can be reduced

You and I can influence decisions

that result in more sustainable management of Renewable Organic Material

to lower costs while reducing the negative impact

on health and environment

Chemical elements that are necessary for plant growth

There are 16 essential plant nutrients (according to Professor Sune Petersson, 1984)

Carbon (C) and oxygen (O) are absorbed from the air

Other 14 elements are obtained from the soil solutionThey are: hydrogen (H), nitrogen (N), phosphorus (P), potassium (K),

calcium (Ca), sulphur (S), magnesium (Mg),

boron (B), chlorine (Cl), manganese (Mn),

iron (Fe), zinc (Zn), copper (Cu),

sodium (Na), molybdenum (Mo)

2013-07-12

Each of the 14 elements should be returned to cultivated soils

We need Sustainable Closing Loops

Local bioconversion – ecologically, economically and socially

sustainable

16 chemical elements & bioenergy

• Are found in all living things and in material derived from living

• Should be used more efficiently

• Technology should help create optimal conditions for microorganisms2013-07-12

Challenges for sustainable management of waste and wastewater

Motivation according to Birger Sölverud, BAS Consultant

Do not release into the air that you do not want to breathe

Do not contaminate water with stuffs you do not want to drink

Do not lay on the ground substances you do not want in your food

Two systems for management of waste and wastewater per person per year in Sweden 1998

FUTURE

Household waste (solid) 350 kg can be treated as follows (according to report

”Reforsk, FoU 145, 1998”):12 % recycling 6 % waste incineration 6 % land filling 76 % can be treated biologically

Liquid waste430 litre (urine and faeces) can be collected

in novel equipment using modern logistics and treated biologically in local facilities together with organic solid waste

Grey water can be cleaned locally by biological processes.

Results: biogas and biofertilizers two locally created valuable products

PRESENT SITUATION

Household waste (solid) 350 kg

12 % recycling50 % waste incineration (create ca 25 % toxic ash)38 % land filling

Liquid waste430 litre (urine and faeces) ends up in about 73 000 litre wastewaterIn wastewater treatment plants• nitrogen disappears out• phosphorus is binding by chemicals• sludge contain various toxic substances

Results: emissions that are polluting and also losses of energy and plant nutrients

Some short definitions

Bio – inspired by the Greek word βίος, bios, = “life”

Biology is study of lifeBiomass – mass of living organismsBioenergy – suns energy bound in biomass Bioconversion - processes involving living organismsBiofuel – food, feed, substrate, biogas, ethanol Biogas – methane + carbon dioxide + other gasesBiofertilizers – fertilizers that contain beneficial microorganisms, plant nutrients and humic substances important for soil fertility / productivity
