Using CM3.3, I looked for textures-environmental with names including 'scrap'. I got this list;
Scrap Metal 1,<kuid:58223:21020>
Scrap Metal 2,<kuid:58223:21021>
Scrap Metal 3,<kuid:58223:21022>
Scrap Metal 4,<kuid:58223:21023>
Scrap Metal 5,<kuid:58223:21024>
Scrap metal,<kuid:129654:19100>
Scrap Metal,<kuid2:129654:19100:1>
Names including 'waste' only gave this;
Treatment Plant 42 v1 Waste Water Sewage Texture 00,<kuid:58223:21060>
Searches on 'garbage', 'rubbish', 'landfill' returned nothing.
Seems like there's an opening for some creator to stop making the millionth grass texture and start making garbage!
