The putrescible waste that goes to landfills generates massive methane emissions, thus increasing the greenhouse effect and accelerating climate change. Composting is one mean to avoid such emissions, at the same time providing the recovery of organic matter by producing improved soil that can be used in a wide range of fields, from gardening to agriculture.
The keystone for a good composting is the separate collection of organic waste (i.e. kitchen waste, catering waste, industrial scraps etc.) from which it is possible to produce a high quality compost, suitable for agriculture and floriculture.
- The composting process takes place essentially in two phases:
- The Active phase, also known as active composting time, where the aerobic oxidation happens and most of the organic carbon is turned into mineral carbon.
- the Curing phase, when the product completes its humidification to the final stable and odorless state suitable for use.
- Entsorga has developed a number of fully proven and bankable proprietary technologies (see box aside) to make it possible to implement composting treatment in a variety of situations: from small and medium plants to large automated plants.
- All technologies are founded on the following principles:
- Speed up the process by means of computer controlled forced aeration.
- Carry out the treatment in enclosed areas kept in negative pressure to avoid odor release
- Very efficient odor control on emissions by means of proprietary biofilters.
- Limited footprint, modularity and upgradeability.
- Use process automation in order to have a 24/7 continuous process control.
- Limit labor cost by using automated equipment.
- Limit operators’ exposure to foul air, dust and possible pollutants. Improve working conditions wherever possible, increase H&S standards.
- Increase as much as possible the reliability of the equipment with continuous improvements.
