Can I save the marinade from my meat ?

I wouldn't save it. It isn't worth risking food poisoning for a marinade. There could be bacteria growing in the marinade which could cause different problems if eaten.

You should not re-use marinade that has been used on raw meat. You can boil the marinade and use for brushing while cooking on the same meat you marinated in it, but I would not use it for any other purpose.

No, you should never reuse marinade. The bacteria from the raw food would make you very sick this is why many recipes tell you to discard it.

No! Marinades used for either beef or chicken is not re-usable because of the chance of food poisoning. It can be deadly or wish you could die kind of sick. Bacteria has already started growing in the marinades. The beef, chicken, and marinade has sat in the kitchen or fridge uncovered. The marinaded beef or chicken would have to be placed in a sterilized bag or bowl with no chance of air creeping in. So do not re-use marinades used for either beef or chicken.

the only marinade re-use that's safe is to boil it immediately to make a glaze or as a base for a sauce (you see this often for grilling recipes).  boil for 6 minutes according to CDC guidelines.  storage is really not a safe option.

This is not the same as a Chinese master sauce, which is a flavorful braising liquid.  the meat (chicken, beef, pork) is simmered in the liquid until fully cooked.  Fat is removed after cooking and the liquid is frozen until the next cooking.  But this assumes that it's used every few days and is boiled each time and the meat is thoroughly cooked each time.

Absolutely not the same as a western style marinade.

if your concern is expense (a lot of ingredients that are thrown away) maybe you'd like to invest in a vacuum sealer?  my tilia forces the flavoring into the meat's cells, so i make only 1/4 to 1/2 cup marinade, vacuum seal for 5 minutes, turn the meat, revacuum for another 5 minutes. i haven't tried it but Reynolds has a small unit that uses special bags (with a valve built in).  I think it's about $10-15; it might be worth looking into....

Also if it fits your recipe, you can slice the meat into strips (like for satay or teriyaki) and put in a food bag with a little marinade, massage a little so the flavorings go everywhere and put this in the fridge to marinate.  this will reduce the quantity needed as well.

Hope this helps. I didn't want you to be discouraged because all the other responses are so gloom & doom: "you'll kill your babies if you reuse a marinade." sheesh.

No!!  It contains raw meat juices.
