SUSANE-I: Sustainable, sanitary and efficient management of animal manure for plant nutrition and environmental protection

SUSANE-II: Optimizing environmentally friendly biogas production from livestock manure for the reduction of green house gas emissions

Phase 1 (2006-2009) and 2 (2010-2014) research capacity building projects in Vietnam

The overall objective of the SUSANE-I project was to enhance the scientific research capacity in Vietnam for developing sustainable management and use of animal manure.

Animal manure is a valuable source of plant nutrients but also a source of diseases and a potential hazard to the environment. The small producers are increasing their pig production significantly on properties with very little land and this will increase risks for an inefficient use of animal manure, for environmental pollutions and spreading of pathogens.

This project focused on optimising recycling of animal manure for small livestock producers, supported by the DANIDA programme ASPS. Further the project aimed to alleviate environmental hazards related to livestock production on large scale commercial farms, which were foreseen to emerge in the near future. The program of research and training involved collaboration between agricultural research institutes in Vietnam and Denmark, aimed at developing and validating sustainable manure management systems through research on farm with focus on:

  1. Management of manure, collection, storage, transport and application,
  2. optimize timing and precision of manure application and
  3. reduce spreading of pathogens

The core issue of the subsequent SUSANE-II project (2010-2014) is the optimal and hygienically safe transformation of organic matter in animal manure into both energy and available nutrients. Biogas technology for production of energy from manure is now gaining popularity in Vietnam, especially on small and medium-scale farms, where simple, underground biogas-reactors are being installed. Manure properties, management and environmental factors are most important factor for biogas productivity, but also for emission of the greenhouse gasses methane (CH4) and nitrous oxide (N2O) and for carbon addition to soils (C-sequestration).

The overall objective is to convert animal manure from an environmentally detrimental waste to a valuable resource through the development of a sustainable Vietnamese manure-based biogas production, contributing significantly to reduction in greenhouse gas emissions and safe and efficient recycling of the biomass for plant production. The activities in the project are organized in five closely linked work packages (see diagram). A number of PhD students (9) and post-docs (3) will be educated through the project. In our group at UC-LIFE we are involved in both WP3 and WP5 activities.
