Method and system for delivering biodegradable shelled portions

A system for delivering over the air, shelled portions of fluids or granular substances containing ingredients to a target, the system comprising:

• a computer configured to select:
• location, height, and speed of an aerial vehicle at a delivery point, based on mission parameters and physical data of a scene containing the delivery point;
• the aerial vehicle configured to convey the shelled portions to the delivery point;
• and
• a dispenser configured to dispense the shelled portions towards the target,
• wherein the shelled portions comprise fluids or granular substances covered by shells made of a flexible bio-degradable or compostable material and weigh each 100 to 300 grams, and
• wherein the shelled portions are homogenous in size, shape and weight, and
• wherein the flexible biodegradable shells are made from a multilayered flexible biodegradable sheet containing polysaccharides at each layer of the multilayered flexible biodegradable sheet.
