1 Optimized recovery of organic waste Compost Council of Canada Annual conference - Calgary September 19, 2017

2 Feedstock, over 260 Mt/a produced in the US alone (almost 1 t per capita) Green waste Wood Manures Food scrap Biosolids (20% DM) 2 I Source: BioCycle January 2017, no data for agricultural waste

3 Organic flows, a deficit in rural areas Animal breeding Agricultural waste Forestry Agriculture Manures Food industry Wood industry Wood & preconsumer food waste? Parks and gardens Food scrap Biosolids Green waste Wood waste 3 I Optimised recovery of organics

4 Integrated recovery routes Protein production Energy generation Soil amendment production 4 I Optimised recovery of organics

5 Returning organics to land 5 I Optimised recovery of organics

6 Direct land spreading Manures Agricultural waste Usually uncontrolled, directly managed at primary production site (farm, plantation ) Pre-consumer food waste Regulated Biosolids Post consumer food waste & green waste In some countries 6 I Optimised recovery of organics

7 Producing compost Organic flows, blended to achieve required moisture content, C/N ratio 7 I Optimised recovery of organics 1- Preparation 2- Composting In vessel Static Forced aeration 3- Maturation Piles, windrows Static 4- Refining Compost (-10 to +20 $/t delivered), depending on feedstock & application

8 Producing enriched compost Organic flows, blended to achieve required moisture content, C/N ratio + enhance final quality requirements 1- Preparation 2- Composting 3- Maturation 4- Refining Compost + Blending product to obtain required properties (drainage, nutrient value ) Dedicated application with higher value (20 to 40 $/t) 8 I Optimised recovery of organics

9 Energy generation 9 I Optimised recovery of organics

10 Anaerobic Digestion Organic flows, blended to achieve required moisture content 1- Preparation 2- Anaerobic digestion Wet/dry Static/with agitator 3- Biogas cleaning, electricity generation Biomethane, electricity, heat Digestate Direct spreading Composting 10 I Optimised recovery of organics

11 Producing an alternative fuel Biosolids Dewatering & drying & pelletizing Alternative fuel, e.g. for cement kilns Clean wood (class 1) Waste wood (class 2), poor quality MSW compost Torrefaction / low temperature pyrolysis & pelletizing Alternative to coal 11 I Optimised recovery of organics

13 Insect farming is becoming a reality Agriculture Biowaste sources Animal Feeding Biowaste Eggs of Black Soldier Fly (BSF) Fertilizer Larvae Oil Protein Green Chemistry 13 I Optimised recovery of organics

14 Black Soldier Fly process cycle in a nutshell BSF: 2 weeks (feed period) Few days (no feed) 5-10d (no feed) Eggs Born larvae Grown larvae Pupas Adulte phase <2% few mm length mm length Hosting the nympha >98 % Harvesting + extraction of final products to be marketed PREPARED INPUT (biowaste or specific organics) 14 I Optimised recovery of organics

15 Animal Content free With Animal content Input material requirements Strong regulation restraints regarding feedstock origin Technical applications (glue ) Feed applications Not addressed for time being Current composting, AD solutions For the time being (in Europe) Protein fraction : PetFood and Aquafeed are allowed to use insects derivate Oil fraction : all animal can be fed with oil derived from insects PRE-CONSUMER POST-CONSUMER Within the next few years (in Europe) Protein fraction use should be extended to other non-ruminant animals (poultry, pork ) Certain Post-Consumer flows coming from traced and safe origins should be added to Pre-Consumer flows 15 I Optimised recovery of organics

16 Process mass balance One single stage for : Processing/transforming the input material Evaporating excess of water Producing up-graded materials from larvae (namely protein & fats) & a fertilizing material 16 I Optimised recovery of organics

17 Oilseed Meal Meat Bone Meal (PAT) Protein consumption and shortage forecast - World population is projected to reach 9,6 billions by Protein production will have to grow by 50% (+265mt) to feed people and to meet the demand from the feed market mainly in dynamic sectors with active growth over the 2 next decades such as Poultry, Aquaculture, PetFood - 2/3 of the total protein world output supply for the animal feeding (more than 1bnt per year) and 1/3 for human food - Current production methods are not able to cope with this growing demand. Around 300mt of protein should be supplied by alternative routes by 2054 for feed, out of which 12% (~30mt) are expected to come from Insect route (Source Lux Research 2016) - Insect Proteins are expected to address few niche (ktpy) application with significant growth perspective within a global and tremendous commodity market (oils & proteins) Range of magnitude of material use in animal nutrition in the world : Oilseed meal (soybean mainly) : 300mtpy MBM : 14mtpy Fishmeal : 7mtpy Others : 100 to ktpy Market size Targeted market applications Fish meal Targeted application markets consuming different protein quality, sourcing and prices Non-feed use Hydrolysates from high grade proteins /kg 17 I Optimised recovery of organics

27 Summary Compost value is currently underestimated as are the long term needs of our agricultural areas. However, with the required quality, demand will grow in the future Recovery routes for organics are mostly complementary Anaerobic digestion allows to: Generate energy Maintain the return to land option Protein production by harvesting insects is a promising route that allows to Produce a high value commodity Preserve the energy & nutrient value of the initial product for further energy generation and land use Fuel substitution options offer a solution to current existing concerns but usually preclude land application options Platforms such as Organix will allow to optimize the recovery of organics and the capacity of processing capacity as well as raise awareness on feedstock and product quality 27 I
