Abstract:

Composting in encapsulated systems follows the general objectives of open windrow composting but with the advantage of : accelerating the rotting process (and thus increase throughput/save space), improving process control and thus product quality, and taking better control over emissions and thus reduce potential nuisances. Composting is an aerobic process that by definition requires oxygen and biologically degrades/converts organic material to CO2, water and humic substances. Composting in encapsulated systems means the composting of biodegradable waste in a closed reactor with minimized thermal exchange with the atmosphere and relies on various methods of aeration and mechanical turning to control the process. These mechanical systems are designed to minimize odors and process time by controlling airflow, temperature, and oxygen concentration. Closed systems make it possible to collect gaseous emissions, odors and particulates. The active aeration, watering and mixing functions enable control and optimization of the rotting process, thus considerably accelerating the main biodegradation phase. Composting in encapsulated systems is more strictly divided into a prerotting and a secondary rotting or maturing stage. Proteins represent 90-95% and include albumins, globulins 30%, gliadin soluble in alcohol 70% and a reduced content of glutenin. Ovenina, the gliadin of oats not form gluten with glutenin and has poor bakery properties. Starch is in top of glucides. Minerals are not distributed uniformly in bean. Oats flour contains vitamins B, PP and enzymes.
