I dry age meat and sell it. I live in indonesia at the moment and its hard to get a hold of this for a reasonable price so i setup some fridges, bought some special bags for dry aging and dry age about 15 kgs of mean at any one time. After I dry age the meat i can sell it for about 4x the price that i bought it for and it makes a decent amount of additional income. I sell it online and through whatsapp also :)
