b) an epoxy resin, wherein the epoxy resin is from about 1% to about 25% w/w of the conglomerate resin; and c) a hardener, wherein the hardener is from about 1% to about 25% w/w of the conglomerate resin. ### Claim 2 (depends on 1) The conglomerate resin of claim 1, wherein a w/w ratio of the waste stream material and the epoxy resin plus the hardener is about 1 to about 1. ### Claim 3 (depends on 1) The conglomerate resin of claim 1, wherein a w/w ratio of the epoxy resin and the hardener is about 100 to about 35. ### Claim 4 (depends on 1) The conglomerate resin of claim 1, wherein a w/w ratio of the epoxy resin and the hardener is about 100 to about 25. ### Claim 5 (depends on 1) The conglomerate resin of claim 1, wherein the waste stream material is about 50% w/w of the conglomerate resin, wherein the epoxy resin is about 25% w/w of the conglomerate resin, and wherein the hardener is about 25% w/w of the conglomerate resin. ### Claim 6 (depends on 1) The conglomerate resin of claim 1, wherein the waste stream material comprises the polyurethane at an amount of from about 10% to about 100% w/w of the waste stream material. ### Claim 7 (depends on 1) The conglomerate resin of claim 1, wherein the waste stream material is derived from manufacture of a sporting goods equipment. ### Claim 8 (depends on 7) The conglomerate resin of claim 7, wherein the sporting goods equipment is a ski, a snowboard, or a split board. ### Claim 9 (depends on 1) The conglomerate resin of claim 1, wherein the polyurethane comprises a cast polyurethane. ### Claim 10 (depends on 1) The conglomerate resin of claim 1, wherein the polyurethane comprises a polyurethane foam. ### Claim 11 (depends on 1) The conglomerate resin of claim 1, wherein the polyurethane has a biobased content of from about 40% to about 90%. ### Claim 12 (depends on 1) The conglomerate resin of claim 1, wherein the microbial oil is derived from a microalgae. ### Claim 13 (depends on 1) The conglomerate resin of claim 1, wherein the biobased polyol has a C18:1 content of at least 60%. ### Claim 14 (depends on 1) The conglomerate resin of claim 1, wherein the waste stream material further comprises one or more species of wood at an amount of from about 1% to about 60% w/w of the waste stream material. ### Claim 15 (depends on 1) The conglomerate resin of claim 1, wherein the waste stream material further comprises recycled or post manufacturing waste fiberglass at an amount of from about 1% to about 40% w/w of the waste stream material. ### Claim 16 (depends on 1) The conglomerate resin of claim 1, wherein the waste stream material further comprises recycled or post manufacturing waste nylon at an amount of from about 1% to about 20% w/w of the waste stream material. ### Claim 17 (depends on 1) The conglomerate resin of claim 1, wherein the waste stream material further comprises an elastomeric material at an amount of from about 1% to about 50% w/w of the waste stream material. ### Claim 18 (depends on 1) The conglomerate resin of claim 1, wherein the waste stream material further comprises rubber at an amount of from about 1% to about 50% w/w of the waste stream material. ### Claim 19 (depends on 1) The conglomerate resin of claim 1, wherein the conglomerate resin is molded into a sheet. ### Claim 20 (depends on 1) The conglomerate resin of claim 1, wherein the conglomerate resin is machined into a sheet. ### Claim 21 (depends on 1) The conglomerate resin of claim 1, wherein the waste stream material has a mean particle size of less than 4 mm. ### Claim 22 A conglomerate resin, comprising: a) a waste stream material, wherein the waste stream material comprises a polyurethane, wherein the polyurethane is formulated with a biobased polyol, wherein the biobased polyol has a C18:1 content of at least 60%, wherein the waste stream material is from about 50% to about 90% weight-by-weight (w/w) of the conglomerate resin; b) an epoxy resin, wherein the epoxy resin is from about 1% to about 25% w/w of the conglomerate resin; and c) a hardener, wherein the hardener is from about 1% to about 25% w/w of the conglomerate resin.
