Advanced grease-capturing solution for barbecue grills

A barbecue grill having a heat source and comprising an integrated grease-capturing system, the integrated grease-capturing system comprising:

• a multi-channel grease drainage tray having an elevated end having a height greater than that of a lower end, the multi-channel grease drainage tray comprising:
• a plurality of channel members, each comprising a narrow center channel running longitudinally along a length of a Y-shaped cross-section of the channel member, wherein grease that drops from food being cooked on the barbecue grill is directed into the Y-shaped cross-section of each channel member and funneled down into the narrow center channel;
• an insulation layer disposed along a bottom of the grease drainage tray providing heat insulation between the drainage tray and the heat source;
• a grease collection tray fluidly connected to the lower end of the grease drainage tray, wherein grease collected in the grease drainage tray drains by gravity from the lower end into the grease collection tray;
• an insulation wall attached to the lower end of the drainage tray and interior to the grease collection tray, the insulation wall providing heat insulation for the grease collection tray from the heat source.
