Provided is an artificial medium for non-edible plant growing, which comprises a matrix material group. With the total volume of an artificial medium as 100%, the matrix material group is at least 80%. With the total weight of said matrix material group calculated as 100wt%, the matrix material group includes: thick silica sand that has weight percentage from 1wt% to 3wt% and particle size from 1.5 mm to 2.0mm calcium carbonate that has weight percentage from 50wt% to 60wt% and particle size from 0.5 mm to 1.5mm diatomaceous earth that has weight percentage from 20wt% to 24wt% and particle size from 0.25 mm to 0.5mm soil that has weight percentage from 18wt% to 20wt% and particle size from 0.05 mm to 0.25mm and thin silica sand that has weight percentage from 1wt% to 3wt% and particle size less than 0.05 mm. For use of calcium carbonate waste through purification and softening process, the present invention can produce an artificial medium for non-edible plant growing to realize environmental philosophy of waste recycling and reuse.一種供非食用植物植生的人工介質,包含一基質組材,以該人工介質的總體積為100%計,該基質組材佔至少80%。以該基質組材的總重量為100wt%計,該基質組材包括:重量百分比為1wt%至3wt%,粒徑範圍為1.5至2.0公釐的粗矽砂;重量百分比為50wt%至60wt%,粒徑範圍為0.5至1.5公釐的碳酸鈣;重量百分比為20wt%至24wt%,粒徑範圍為0.25至0.5公釐的矽藻土;重量百分比為18wt%至20wt%,粒徑範圍為0.05至0.25公釐的土壤;及重量百分比為1wt%至3wt%,粒徑範圍為小於0.05公釐的細矽砂。利用淨水軟化過程中產生的碳酸鈣廢棄物,能製造出供非食用植物植生的人工介質,落實廢棄物處理再利用的環保理念。
