IIGE is a research institute that promotes development, innovation and transmission of technology focused on energy efficiency and renewable energy. The institute aims to contribute to the sustainable development of the Ecuadorian society, through the implementation of energy efficient and energy renewable policies and projects.

This invention is a process for manufacturing water-insoluble lignin-agglomerates in the form of granulates or briquettes from liquor left over as waste from processes of cellulose-extraction. The extract can be used energetically or materially. The extract is firstly granulated through spray-granulation or mix-agglomeration leaving lignin-agglomerates then is treated with acid lowering its pH-value and making it insoluble in water. This process can make not only lignin-granulates but also lignin-briquettes.

The main principle of this toilet is the separation of solid and liquid waste which is then later used for generation of biogas.

The CTCN is collaborating with the Government of Congo on a feasibility study for the creation of a centre to monitor health and environmental risks in Pointe-Noire and possibly encompassing other countries in the Gulf of Guinea.

Background

Tofu and tempe are fundamental to the Indonesian diet. Demand for these products is served by an industry of small and medium sized enterprises (SMEs) employing 285000 workers in 85000 businesses. Production practices are extremely energy inefficient and environmentally damaging. Enterprises use firewood resulting in a per-factory emissions average of 450 tons CO2/year and sector-wide emissions of 30 million tons.

L’industrialisation des pays en voie de développement engendre l’augmentation des déchets liquides que sont les huiles de vidange, tout en se heurtant au problème de déficit énergétique. D’autre part, elle s’accompagne d’une forte croissance démographique qui accentue et augmente la quantité de déchets, particulièrement les déchets ménagers solides. Ce qui constitue une réelle menace pour l’environnement et les populations.

The goal of this project is to develop a web-based tool for small and medium-sized farms to be able to estimate potential renewable energy MWh and GHG reduction and costs for adding biodigestors to produce biogas for fuel and to reduce environmental impact from disposal of untreated liquid wastes.

Output

• Computer-Based Tools to Estimate RE Production and GHG Reductions from Biodigestion of Animal Waste

The goal of this project is to develop a web-based tool for small and medium-sized farms to be able to estimate potential renewable energy MWh and GHG reduction and costs for adding biodigestors to produce biogas for fuel and to reduce environmental impact from disposal of untreated liquid wastes.

Outputs

• Report on Field Trials for the Tool in 3 Reference Animal Farms

Black liquor gasification is an emerging commercial technology founded on decades of research and development. Its goal is to produce a combustible mixture of raw gases as well as separate out the inorganic pulping chemicals for recycling for the pulping process. The processes can take place at low, 600 degrees Celsius, or high temperatures around 1000 degrees Celsius.
