Toxics Release (TRI) is a EPA database which contains information on listed toxic chemical releases and other waste
management activities to be reported annually by companies who meet minimum quantity thresholds. This TRI was established by the Emergency Planning and
Community Right-to-Know Act of 1986 (EPCRA) and expanded by the Pollution Prevention Act of 1990.
Since 2000 we have developed nearly 500 databases for clients throughout the world. See a sample of them at our recent clients page.
15 years ago we were putting Access database on the web using Active Server Page (ASP) programming language for the user interface. See examples of Access on the Internet.
Companies in the USA must report
the handling of a long list of chemical each year to the US government. The major streams of chemical handling are releases,
transfers and recycling/recovery. A data analysis screen is show below for our TRI Data Analysis database. The database
was originally written in the 1st version of Microsoft Access in 1994.
The interface allows the user to drill down to four levels
of data and these can be selected in any combination - chemical, year, state, etc. Additionally, the data may be filtered to
include Releases, Transfers, or Recycling & Recovery data.
