![]() In doing so, WUR contributes to the circular economy in the Netherlands. They are for making great compost and NOT for makin. Through this project, WUR works on a relatively low-tech solution for high-volume biomass (such as manure and clippings) as a substrate for the growing insect industry. Composting businesses can make a cheaper and more sustainable substrate for insect breeding, benefiting the breeders. The study aims to add value to “worthless” waste streams such as grass clippings and manure by making them suitable for the breeding of insects. Composting techniques in combination with fungi are also applied to make it easier for insects to process the wood-like elements in clippings. Unwanted substances, such as veterinary treatment residues in manure, can also be broken down in the composting process. A mushroom is a fungus, and fungi have the ability to break down or absorb unwanted materials. The project leans on the existing knowledge and expertise of the mushroom farming industry. If this is the case, insects may be used as an ingredient in animal feed, thus reducing the use of less sustainable feedstock (such as imported soy). You can compost just grass clippings, but you will have a stinky mess when you do, because the excess Nitrogen from that pile will escape to the atmosphere as. The substrate is then analysed to check if it is safe and rich in nutrients. grass clippings, annual weeds, vegetable kitchen waste, or manure) to feed the micro-organisms. You can purchase corn-gluten meal online or at some gardening stores. Sprinkle the meal on top of the compost to increase the composts nitrogen levels. ![]() To make so-called waste streams such as manure, ditch and grass clippings suitable as a substrate for insect breeding, the researchers must first compost and ferment them and grow fungi on the compost. Aim for between 25 and 50 percent soft green materials (e.g. Read the instructions on the back of the corn gluten meal to know how much you should add to your compost.
