Innovative processes for the management of livestock waste
The integrated use of two prototypes for the extraction of effluent from pig:
- Ammonium Salts: fertilizer that remove ammonia component
- Biochar enriched: able to give a nutrient supply and structural benefits to the soil, improving fertility, increasing water retention and increasing adsorption and biodegradation of herbicides with carbon sequestration, enriched with an organic compound, pasteurized, free from harmful substances or volatile, biologically inert.
- Aqueous effluent: having characteristics such as to be suitable for reuse in the same digester or to discharge to surface water reused in the company being a water free from minerals or inthe circuits of the two plants.
- Digestate Collection and storage.
- Digestate treatment using two prototypes ("evapoconcentratore" carbonizer): the combined use of the two prototypes will enable the conversion of the digestate into a fertilizer, organic fertilizer and nitric acid; in energy from renewable sources with low emission of pollutants.
- Use of biochar as a soil enriched agronomic rating.
- Laboratory analysis to characterize the products obtained.
1) MANAGEMENT ACTION (STUARD, SSICA, UCSC, CFSIVT, SCVSA)
Stuard will assume the role of coordinator of the GO, planning and implementing all the initiatives required to achieve the results provided by the Plan For this reason, it will employ its own, technical and administrative staff, qualified and equipped with multi-year experience in the coordination of research, experimentation and dissemination project activities.
The staff will operate in accordance with specific management procedures and operational to ensure a proper conduct of the activties (staff training, evaluation of suppliers, implementation of project activities, verification and assessment of compliance of the operations and results obtained with respect to the expected results).
From the operational point of view, Stuard as Head of Plan (RP) will coordinate:
• overall activities;
• animation and dissemination actions, described in the plan.
2) STUDY ACTIONS NEEDED FOR THE IMPLEMENTATION OF THE PLAN (MARKET, FACTORY, BUSINESS PLAN, ECC): (SCVSA)
The aim is to evaluate the economic sustainability of the project for agronomic, energetic and food use of the products obtained through digestate treatment. The alternative use of digestate, proposed under this project, involves a significant reduction in the management and environmental costs of cogeneration residues and market value enhancement of the products resulting from the conversion process of such residues, such as ammonium salts, biochar, thermal energy, and polyphenols usable in food supplementation. In addition in order to have a positive impact on the economy of the agro-energy supply chain, the project will result in a number of beneficial effects on human well-being through the generation of positive externalities.
Costs and benefits will be assessed at every level of the chain in the perspective of optimizing, in a long-term perspective, the economic efficiency of technological transformation.
Action 3.1 Pig digestate digestion and storage (Stuard, and Farms)
Stuard will be responsible for the collection of the digestate produced by the CAMPO BO 'farm biogas plant and the collection of the ammonium salts obtained from the process of the treatment of the digestate (prototype SSICA), which will be collected in special containers and subsequently used for the production of "fertilizer mixtures" with biochar. Farmers will support, through the provision of conveyors and mixers, Stuard will take care of the transport of materials from the place of production to the field and their subsequent distribution.
Stuard will be responsible for transporting the digestate from CAMPO BO 'to Tecnopoli of the University of Parma, where the carboniser is located, and the subsequent transport of the biochar to the experimental and use sites.
Action 3.2 SSICA prototype digestion treatment (SSICA)
- 2 EFFECT EVAPORATORS AND TWO STAGES:
The system operates two counter-current effects, in which the product to concentrate enters in the Second Effect (II Effect / 1st Stage) and transferred to the First Effect to achieve the desired concentration.
- EVAPORATOR CONDENSATION CONCENTRATION
The system is designed to concentrate on coated spiral polymer osmosis (RO) membranes.
This section will be 'double pass' to ensure the highest concentration possible and at the same time the best quality of the permeate,
Process management and control of operating parameters must be governed by a software and control panel with a high level of automation.
Action 3.3 Carbonisation and subsequent carbonization (CFSIVT, SCVSA)
CFSIVT (Tadini) has in use an innovative micro carboniser (patent WO 215/018742), equipped with a specific feed-back system and biomass. The technological innovation of the product consists of the possibility of carbonization, without pretreatment, of waste materials as a sustainable source of thermal and electrical energy, using a dual power supply and a control system that optimizes the proportions of input materials. But true innovation lies in the product obtained by carbonization, a process that converts matter. The plant is fully automated, controlled by a control unit (PLC) that automatically manages all thermodynamic cycles without operator supervision. The software is designed to look for the ideal conditions for optimizing the process according to the different available biomass, based on temperature, pressure and flow rates, detected by sensors located at various points in the plant. Integration with telecommunication systems (ICT) guarantees local and global automation and processing.
Six months are planned for the feeding system, during which it will be biochar product, which will be used for autochthonous harvesting tests at farms.
Action 3.4 Agronomic tests (Stuard, and Farms)
The experimentation will last two years, the trial fields will be carried out at Società Agricola Alfieri Antonio, Bruno and Attilio and the Experimental Agricultural Stuard Company, while the CAMPO BO 'farm will provide the various fertilizer matrices for the entire duration of the experimentation (digested with pigs from biogas and ammonium salts).
From the spring 2018 (with spring seed sowing), farms will be responsible for soil preparation, sowing and crop management in accordance with good agricultural practices of PGIs in collaboration with Experimental Stuard Agricultural Experts.
Experts from the Stuard Experiment Company will assist and assist farmers during soil preparation, planting, and handling for the entire duration of the project while performing the preparation of the various fertilizer matrices together. The Stuard Experimental Farm will also focus on the testing and definition of the experimental protocol, the choice of varieties to be included in the experimental fields, the design of field patterns and seed detection, andthe distribution of the various fertilizer matrices in collaboration where necessary, withfarms.
In each company, a field with an experimental design will be created that involves the use of two different cycles of rotation:
- at the Agricultural Society Alfieri Antonio, Bruno and Attilio (spring 2018) first year corn,second year wheat
- at the Experimental Agricultural Stuard (spring 2018) first year corn, second year wheat.
Action 3.5 Laboratory Analysis (UCSC, SCVSA, SSICA)
Biochar Analysis for Its Use as Amendment (SCVSA)
SCVSA will perform basic analyzes for biochar and soil characterization. Polyphenols in TAR (UCSC)
