One embodiment provides a modular green roof tray, house plant growth media and horticulture growth media, and a tree protection mat for weed and moisture control made from recycled disposable diapers. The growth medium and tree protection mat contain superabsorbent materials from diaper that can absorb waters and greatly reduce irrigation so to provide a drought resistant feature. One embodiment also provides a manufacturing process to perform 100% recycling of disposed diapers.

Tree or plant protection mat

A compound is provided, having the formula (I), wherein Ris a soft block polymer; wherein each T is independently a urethane or urea linkage; see formulae (A) and (B); wherein each Ris independently &#x2014;CH, &#x2014;CHCH, &#x2014;CHCHCH, or &#x2014;CHCHCHCH; wherein each R'is independently &#x2014;CH, &#x2014;CHCH, &#x2014;CHCHCH, &#x2014;CHCHCHCH, or &#x2014;OR; and wherein each p is independently 1, 2, or 3. Compositions containing the compound, and methods of making and using the compound are provided.
