Easy Green Gel
Play Chapter 7 on the Survival difficulty. While progressing, conserve as much ammunition and trap parts as possible. Try using the existing spike traps to kill various enemies. If done correctly, you will encounter the Keeper boss with approximately 30 traps and a decent amount of ammunition for your various weapons. Begin the Boss battle as normal by shutting down the poison gas. After closing the final valve, remain in the area and keep fighting. The Keeper boss will keep respawning from the safes about 30 times. Keep defeating him to get 2,000 Green Gel each time. With fully upgraded damage on your harpoon bolts and pistol, only one hit with each of those weapons will be needed to defeat him. By the end of all the fights, you should have collected approximately 70,000 Green Gel. Note: You cannot damage the Keeper for a few seconds after he spawns. To get more trap parts, use the Keeper's barbed wire mines. Simply wait for the Keeper to deploy his mines, then kill him. Use the free time during his respawn to disarm the mines. Additionally, keep a sniper rifle or shotgun as a backup weapon in case you run out of harpoon bolts.
