This technical process, known as REnescience, was developed by the Danish energy company DONG Energy. REnescience is a microcosm of the current worldwide “turning waste into energy†project (especially in Europe). The commonly used first type of "waste-to-energy" strategy is to burn waste and generate energy. A typical incinerator emits about 830 g of carbon dioxide per 1 kWh of electricity produced, which is better than a coal-fired power plant (800-1300 g of CO2 per kWh of electricity) and 400-900 g CO2/kWh of gas-fired power plants. However, critics have pointed out that incinerators generate a lot of heat, and useful resources represented by plastics are simply burned in the process. However, in some countries, these heat sources have been used for heating. In Denmark, waste incinerators supply 5% of the country's electricity and 20% of local heating needs. The second type of "waste-to-energy" strategy is the "mechanical-biological" treatment method, which requires the collection of biodegradable materials from Municipal Solid Waste (MSW), followed by anaerobic digestion to produce methane, and digestion. Residual solids become a valuable nutrient-rich compost. Source waste classification is a stumbling block to this strategy. Mechanical classification in centralized facilities often results in 30% to 70% of degradable materials being wasted. In contrast, enzymes can process unclassified MSWs and automatically extract organic materials for the production of large amounts of clean energy. According to research, the production of 1kWh of electricity at the REnescience pilot plant near Copenhagen requires only about 590g of CO2 to be emitted. The enzyme packages used by REnescience include cellulases, lipases, and proteases. Cellulases have been used in commercial processes to convert corn stalks into fermentable sugars; lipases and proteases can degrade fruit and vegetable hides and waste paper into sugars and organic acids. Today REnescience is also controversial, one reason being that the technology's environmental impact life cycle analysis suggests that it may not be more environmentally friendly than the top incinerators. Environmentalists also worry that the prominent convenience of the technology may be detrimental to the classification and recycling of household waste that is currently maturing in European countries. They believe that waste separation and recycling will always be the core of a sustainable waste treatment system because it can fundamentally reduce overall waste. As to whether REnescience is more environmentally friendly than other methods, professionals believe that the impact on the overall environment is determined by a series of factors. When dealing with high organic raw materials, enzymatic methods have less impact on global warming than incinerators, but for low organic materials Incinerators are even better. The form of energy that people want to obtain is also an important reference. If energy is needed, the enzymatic method is better, but if you consider the local heating, then the incinerator will win. All in all, the state-of-the-art incinerator and the mechanical-biological treatment method have the same environmental impact and surpass the landfill. At present, REnescience still faces many problems. First, about one third of MSWs cannot be recycled as energy and can only be burned. And 35% of the biogas obtained through anaerobic fermentation is carbon dioxide, which can only be released into the atmosphere. At the same time, the remaining solid sludge after bacterial treatment is currently not available as a compost for food crops due to possible trace contaminants. DONG will solve these problems through the fine-tuning of processing procedures. At present, DONG has reduced the amount of enzymatic enzymes by about 75% to improve economic efficiency. If REnescience performed well in the first year, DONG hopes to build more factories in the UK, the Netherlands and Malaysia. However, the actual implementation will depend on national policies.
