Benefits of technology

This patented technology allows creation of highly valuable products from ulvaglandia plants through an efficient process called biofertilization (B). By producing this product with specific types of bacterial strains, we aim to provide more effective ways to use these materials without causing harmful environmental impacts such as deforestations caused by overfishing fisheries or pollution due to landfill disposal methods used during mineral extraction processes. Additionally, B produces wastewater containing certain nutrients like nitrogen, phosphorus, calcium, magnesium, sulfur, iron, manganese, etc., making them useful resources instead of burning coal. Overall, BioFertility offers various benefits including reducing carbon dioxide emission, utilizing natural sources while preserving eco-friendly environments, providing technical solutions towards improving agricultural efficiency, protecting aquatic systems, controlling sea level temperature, generating energy crops, and developing other beneficial applications related to microbial growth.

Problems solved by technology

This patented technical problem addressed in this patent relates to finding ways to use bioenergy sources like sewage/biocrafts, vegetables, animal husbandry, crops, forest residues, turtles, shellfish, amphibious animals, creatures, and plants grown around coast areas where they were developed during harvest periods due to their high nutritional values compared to traditional fossile fuels.

Embodiment Construction

[0019] Implementation and effect of the present invention are as follows:

[0020] 1) Experimental materials

[0021] Ulva Ulva: salvaged from the sea area of ​​Qingdao City, rinsed with clean water and air-dried. The TS of Ulva kongus was 86.28% and the VS was 72.50% as determined by biogas fermentation.

[0022] Inoculum: Enriched by pig manure in 1999, the Yunnan Provincial Key Laboratory of Rural Energy Engineering of Yunnan Normal University and the Key Laboratory of Advanced Technology and Preparation of Renewable Materials of the Ministry of Education added pig manure for long-term cultivation and preservation. The TS of the inoculum was 8.27% and the VS was 60.85% by biogas fermentation.

[0023] Fermentation device: 1000ml self-made experimental drainage and gas collection fermentation device, the displacement (gas production) has been calibrated.

[0024] Gas analysis instrument: HP4890D type.

[0025] 2) Experimental method

[0026] Using 6 sets of devices, the...

Abstract

The present invention relates to marsh gas fermentation technology, and especially the application of alga viva pertusa in fermenting to produce marsh gas. By means of utilizing the biological features and resource superiority of alga viva pertusa, alga viva pertusa is utilized in fermenting to produce marsh gas. The present invention has the advantages of high quality of marsh gas, utilizing the marsh gas residue as high quality organic fertilizer and soil improver, reducing fossil fuel consumption, propagating viva pertusa to improve marine environment and avoid red tide, and high TS and VS gas creating rate.
