1 20 th Congress Soroptimist International of Europe Berlin 12-14 July 2013 Ruzena Svedelius AgrDr 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 2013-07-12Ruzena Svedelius AgrDr 2

4 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 2013-07-12Ruzena Svedelius AgrDr 4

5 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 2013-07-12Ruzena Svedelius AgrDr 5

6 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 solution They 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) 2013-07-12Ruzena Svedelius AgrDr 6 Each of the 14 elements should be returned to cultivated soils

7 2013-07-12 Ruzena Svedelius AgrDr 7 We need Sustainable Closing Loops Local bioconversion – ecologically, economically and socially sustainable SOILS RENEWABLE ORGANIC MATERIAL  Collection  Transport PRODUCKTION LINE Biological treatment  Local  Efficient  Hygienic  User friendly Biogas Biofertilisers Electricity/Heat/Fuel PRODUCERS  Plants CONSUMENTS  Animals  Industries  Households

8 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 microorganisms 2013-07-12Ruzena Svedelius AgrDr 8

9 2013-07-12Ruzena Svedelius AgrDr 9 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

14 Ruzena Svedelius AgrDr 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 waste 430 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 % recycling 50 % waste incineration ( create ca 25 % toxic ash ) 38 % land filling Liquid waste 430 litre ( urine and faeces ) ends up in about 73 000 litre wastewater In 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 UNSUSTAINABLESUSTAINABLE 14 2013-07-12

15 Some short definitions Bio – inspired by the Greek word βίος, bios, = “life” Biology is study of life Biomass – mass of living organisms Bioenergy – suns energy bound in biomass Bioconversion - processes involving living organisms Biofuel – food, feed, substrate, biogas, ethanol Biogas – methane + carbon dioxide + other gases Biofertilizers – fertilizers that contain beneficial microorganisms, plant nutrients and humic substances important for soil fertility / productivity 2013-07-12Ruzena Svedelius AgrDr 15
