Description

The typical simple payback for a biogas plant may be about seven years as long as the existing government incentive program is available and biogas energy is produced continuously without interruption except for scheduled regular maintenance. Some experiences in North America show that biogas energy production is often interrupted due to unforeseen maintenance and process related issues. Even though anaerobic digestion is a century-old process, the adaptation of this process successfully on the commercial scale for producing energy is still evolving. Frequent interruptions in the process show that the technology and process related knowledge still have room to improve. Despite these drawbacks, the potential for carbon trading and increased consumer awareness regarding practicing environmentally sound and sustainable agricultural production methods will certainly add to the benefits of continuing to work with this technology.

Description

Pre-cooling is the key component in the preservation of quality for perishable fresh produce in post-harvest systems. Pre-cooling is also very closely linked to the other operations such as handling and storage. The practice of pre-cooling fruits and vegetables after harvest has existed for many years. In that time, several methods and techniques of pre-cooling were developed, primarily to meet requirements of the large producers and markets in the United States and Europe.
