The Education for All Handicapped Children Act (P.L. 94-142) of 1975 and the Individuals with Disabilities Education Act (IDEA) (P. L. 101-476) identified specific categories of disabilities under which children may be eligible for special education and related services. The most recent legislation, the IDEA Amendments of 1997 (P.L. 105-17), allows states and local education agencies to apply the term developmental delay for children ages 3-9.
Upcycling, also known as creative reuse, is the process of transforming by-products, waste materials, useless, or unwanted products into new materials or products of better quality or for better environmental value.
There is some evidence for use of the word upcycle as far back as 1994, but the term was first brought into the spotlight by US architect William McDonough and German chemist Michael Braungart in a 2002 book entitled Cradle to Cradle: Remaking the Way We Make Things.
