Recovering waste materials in pineapple processing | Philippines | 1994-1995 | Full scale |
MANUFACTURE OF FOOD PRODUCTS AND BEVERAGES # 37
Background:
Del Monte Philippines, Inc., is one of the largest producers of processed pineapples in the Philippines. The company currently produces an average of 1459 tons of canned pineapple per day. Del Monte has more than 3800 employees. A Pollution Management Appraisal (PMA) was conducted for Del Monte Philippines Inc., to minimize wastes, conserve resources, reduce environmental risks and improve process efficiency.
Cleaner Production Principles:
Housekeeping
Cleaner Production Application:
One of the waste minimization options implemented by the facility was the installation of collection pans or dripping pans in the fruit preparation and trimming tables. These pans were installed in the fruit preparation and trimming tables to collect fruit drops and juice drips. The pans are located underneath the tables to catch the fugitive juice drops and drips from the handling of decored fruit. At the time of the PMA, these pans were installed in only two pilot tables. However, because of the success of the pans, they have now been installed in all the fruit preparation and trimming tables. In addition, Del Monte introduced improved monitoring and supervision which recovered more than 60 kg an hour of lost pineapples.
Environmental and Economic Benefits:
The environmental and economic benefits of implementing the housekeeping option are:
![]() | Pineapple juice was saved at the rate of more than 55 litres / hour. |
![]() | The installation of these pans has also addressed the employees' concern that the drops are acidic and may have affected their skin and clothes. |
![]() | Improved monitoring and supervision saved a further $24 000 a year. |
The investment involved and the resultant economic benefits are as follows:
Item | US $ / year |
Capital Investment | 17,800 |
Net savings from the additional juice collected | 24,000 |
Payback period | 9 months |
Constraints:
None reported.

Review Status:
This case study was originally published in the UNEP IE document "Cleaner Production in the ASIA and Pacific Economic Corporation (APEC) Region. In the process of preparing the document the case study underwent a technical review. Subsequently a second technical review was done by Dr. Prasad Modak, Environmental Management Centre, Mumbai, India in September 1998.
