Definitions

  • the present invention is related to a process of producing soil amendment from organic waste, in particular a process of producing semi-finished products which can be mixed and matched to form specified fertilizer and soil improvement products from organic waste as raw materials.
  • Composting is a technology for treatment of biodegradable (organic) waste.
  • the main advantages of successful composting are a decrease in waste volume; the elimination of most organic toxic compounds, pathogens and pests (potentially present in the original waste) and a transformation of organic matter and nutrients into a stable product that acts as a soil amendment.
  • Composting is a biological aerobic process in which microorganisms convert organic materials and utilize primarily N and C compounds to grow and convert the biomass to a more stable earthy organic material.
  • In-vessel composting is to some degree introduced to ensure hygienization (two days above 60 °C) and to kick-start the composting process.
  • In-vessel residence time varies from a few days to a month, followed by weeks to months of maturing at lower temperatures, typically in windrows.
  • Britannica defines 'fertilizer' as "natural or artificial substance containing the chemical elements that improve growth and productiveness of plants. Fertilizers enhance the natural fertility of the soil or replace the chemical elements taken from the soil by previous crops.”
  • Chemical fertilizer on the other hand, made for an agricultural revolution by making fertilizer with balanced amounts of nutrients available in the end-product.
  • the content of nutrients is designed in accordance with the needs required for different crops and soil, and in a repeatable manner.
  • chemical fertilizer can easily replace the amount of nutrients removed by crops.
  • the chemical ones contain low to none amounts of carbonaceous material.
  • crops, and some soil with them are removed, the levels of organic matter in the soil have dropped significantly the last decades.
  • the ability of the soil for storing and buffering the nutrients from chemical fertilizer is reduced, leading to eutrophication and high run-off levels. As a consequence, more and more attention is given to soil degradation as a big, future challenge within agriculture.
  • WO 2010/139028 A1 describes a method of producing electric power and fertilizer from combustion of biomass, e.g. straw from cereal crops, by producing a liquor from compounds extracted from the exhaust gas, and a fertilizer by composting organic materials in the presence of the liquor.
  • the main object of the invention is to provide a process of treating organic waste to produce valuable products that can be recycled to increase plant growth with high degree of efficiency.
  • wet organic waste is meant to include wet waste (e.g. dry matter (DM) 2-50 %) as such, but also dry waste obtained through some drying process.
  • DM dry matter
  • structural material is meant to include a carbon-rich bulking material which serves as carbon source for microorganisms, providing porosity and air movement through the mass as well as high level of gas diffusion and is typically wood chips preferably in a dry state.
  • biomass is meant to include carbonaceous material of biological origin converted to char by a pyrolytic process, typically shredded, wooden material.
  • “Third generation composting” is meant to describe an aerobic microbial process in a closed reactor where decisive parameters (e.g. composition of feedstock mix, retention time and speed through drum, addition of other substances such as oxygen and gas exchange rate) are monitored and adjusted to obtain desired output in a predictable and repeatable way.
  • decisive parameters e.g. composition of feedstock mix, retention time and speed through drum, addition of other substances such as oxygen and gas exchange rate
  • compost is used to describe the wet mass coming from the drum outlet after the composting process, excluding the gaseous phase.
  • the present invention is related to a process of producing fertilizers and soil amendments from organic waste, ideal feedstocks typically have 55 - 65 % moisture, high nutrient levels, well balanced C/N ratio and functional structure material size distribution, said process comprising the steps of: feeding wet organic waste including added biochar together with structural discontinuous shredded or similarly treated wooden material to form a feed mixture in conduit to a composting drum, subjecting the mixture in said composting drum to a controlled process of microbial aerobic conversion for a prolonged period of time and at an elevated temperature to produce: a solid phase comprising wet compost with biochar, and a gaseous phase comprising substantially humid air with elevated levels of CO2 and ammonia.
  • the process further comprises the steps of: feeding the solid phase to a dryer to remove water from the solid phase and produce dry compost in conduit, feeding the dry compost to a solid-solid separator to extract the structural material from the dry compost fine fraction having a desired maximum diameter range, and then: feeding dry compost substantially free from structural material in conduit to a mixer, feeding separated structural material in conduit to a structural material reception, feeding said gaseous phase from the composting drum to an ammonia absorber to perform gas scrubbing producing: a gaseous phase substantially free from ammonia, and a liquid phase comprising ammonia salts, feeding the liquid phase comprising ammonia salts the mixer, and feeding ammonia enriched compost from mixer to a fertilizer reception.
  • the scrubbing step is advantageously performed by means of an acidic fluid, e.g. an aqueous solution of nitric acid HNO 3 (aq), an aqueous solution comprising sulfuric acid H 2 SO 4 (aq), or an aqueous solution of phosphoric acid H 3 PO 4 (aq).
  • an acidic fluid e.g. an aqueous solution of nitric acid HNO 3 (aq), an aqueous solution comprising sulfuric acid H 2 SO 4 (aq), or an aqueous solution of phosphoric acid H 3 PO 4 (aq).
  • the process further comprises the steps of feeding structural material, ideal feedstocks have 10 - 20 % moisture and high lignin content, such as field residues or woody biomass, to a pyrolysis reactor to produce: a solid carbonaceous material in conduit, and feed the solid carbonaceous material to said mixer as a carbon supply to the fertilizer end product in fertilizer reception, and a gaseous phase, and feeding the latter to the dryer, serving as a heat source to the dryer.
  • ideal feedstocks have 10 - 20 % moisture and high lignin content, such as field residues or woody biomass
  • At least a part of the solid carbonaceous material can be used in a filter to extract ammonia from the gaseous phase from composting drum. Suitable amounts of biochar is added to the composting process, as it contribute positively to the composting process and binds up more nitrogen in the solid phase and the biochar itself gets activated.
  • the invention is also related to a fertilizer for use in agriculture, produced by the process according to the process steps above as well as a product-by-process stemming from separating the fine fraction of the solid phase, for example ⁇ 2 mm.
  • Fig. 1 is an overall process flow diagram of the process in accordance with the present invention.
  • Fig. 1 illustrates a simplified flow sheet of the process in accordance with the present invention, indicated by reference numeral 100.
  • Wet organic waste 101 together with of structural material 102 and biochar from 118 or other source is fed to a composting drum 107 via a hopper 103 and a screw conveyor 104.
  • the wet organic material should ideally be pre-treated by size reduction to a D max of 12mm for sanitation purposes.
  • the structural material is typically shredded wood material with several purposes: Large pieces increase stirring/cavitation and gas distribution, smaller units has large relative surface and serves as good carbon sources for microbial activity in the composting drum 107.
  • Particle size distribution of structural material is ideally of a wide range, from dust particles to larger material.
  • the carbonaceous material commonly known as biochar has an overall positive impact on the composting process as well as retention of nitrogen. Addition of 2 - 10 % dry substance mix have significantly positive properties, with typically 5 % of DS giving good results.
  • the biochar added should ideally be in particle size range D mm 0,5 mm to D max 2,0 mm for optimal separation and effect.
  • the mixture of wet organic waste with biochar and structural material is subjected to microbial aerobic conversion to form compost in a manner known per se. While feeding and unloading is typically done batchwise (e.g daily) the composting process conditions are of a more continuous nature with a steady movement from loading side to unloading end of the reactor. While expertise in the field normally advise against temperatures over 65C a desirable process parameter here is a relatively steep increase in temperature to reach 70-75°C in a section of the reactor. Contrary to common practice present method facilitate for such high temperature conversion until the microbial population change and temperature is reduced.
  • the composting drum 107 is typically a rotating (inclined) drum with flights, preferably equipped with sensors, at least for temperature control, and with possibility for forced ventilation to ensure aerobic conditions.
  • the resulting compost in conduit 108 is fed to a dryer 109 where remaining humidity is evaporated and rejected to the surrounding air via a purification device, e.g. a cyclone (not shown).
  • the resulting dried mixture in conduit 110 is then fed to a solid-solid separator 111, e.g. in the form of a sieve, where the majority of structural material, having relatively coarser structure than the compost fines fraction, is separated from the dry compost in separator 111 and fed to a structure material reception 117 via conduit 116.
  • FFaB fine fraction from composting and activated biochar
  • FFaB may be applied as a standalone soil amendment product.
  • FFaB also serves as a highly efficient base/intermediate for composing a wide range of nutrient specific organic based fertilizers; thus competing with the flexible product range of chemical (“mineral") fertilizers but substantially more sustainable.
  • a substantial part of the nitrogen in such products may come from the ammonia recovery in the process (120).
  • the desired fraction> more than about 2 mm will mainly be structural material. From its origin (shredded wood) this fraction also has changed properties as a consequence of the process: More stable, reduced carbon content and with changes in the relative amounts of lignin, hemicellulose and cellulose. Based on its positive effects in soil (e.g. water retention ability, stimulating soil life and more) this fraction is an important ingredient in peat replacing products which also includes FFaB. It should be emphasized that the desired maximum diameter range will vary with the desired goal.
  • This fine fraction (FFaB) and the post composting structural material serves as excellent intermediates to form an organic based soil amendment and fertilizer product line.
  • Mixtures of converted wet organic waste, some sufficiently degraded structural material and biochar is characterized by high carbon and humus content with good soil amendment properties and as an intermediate product for producing organic fertilizer with high NPK-content.
  • Dry compost in conduit 112 is fed to a mixer 113, where the compost is mixed with additives to enrich the compost in view of fertilizing purposes.
  • the gaseous phase from the composting drum 107 is discharged in conduit 119 by means of fan and can be fed to an optional nitrogen absorber 120 to enrich the resulting end product (fertilizer) with nitrogen compounds.
  • the nitrogen absorber 120 is advantageously a gas scrubber, where the gaseous nitrogen containing discharge 118 from composting drum 107 is subjected to nitrogen absorption by a liquid solution of sulfuric acid or nitric acid, producing a gaseous outlet (not shown) which is subjected to purification before being discharged to the surrounding air, and a liquid outlet in line 121 comprising water and solvated ammonium salts, e.g. sodium nitrate NFI 4 NO 3 .
