“…Based on a design parameter retrieved by real plants, the volume required by AD may be assumed as 0.75 m 3 t OFMSW −1 . Considering the input OFMSW mass flow of 35,000 t y −1 and the duration of AD in the case of mesophilic conditions (four weeks), the anaerobic digester would require a volume of about 2,000 m 3 . If assuming that the anaerobic digester is 5-m high, the occupied surface would be approximately 400 m 2 .…”

“…This is the case, for instance, of methane (CH 4 ) and nitrous oxide (N 2 O). The mean emission factors of CH 4 , N 2 O and carbon dioxide (CO 2 ) were recently estimated as 239, 3 and 2,242 mg/m 2 /h, respectively, from an uncovered landfill in China [3]. Such values should be corrected by considering the global warming potentials of CH 4 and N 2 O, which are 32 and 282, respectively [4].…”

The sector of biomethane production is receiving growing consideration in Europe, as an evolution of the conventional exploitation of biogas in combined heat and power (CHP) generators. From the technical point of view, a common need is to have available tools and calculations suitable for analysing the environmental advantages of this approach. The present paper compares the emissions of air pollutants related to three options for biogas valorisation from waste anaerobic digestion (AD) plants equipped with a post-composting stage: (1) CHP generation and electric energy supply to an electricity distribution network, and biomethane production through (2) pressurised water scrubbing and (3) chemical absorption. In the last two cases, biomethane is considered useful for natural-gas buses for the public. The results demonstrate that option (1) produces a lower amount of global pollutants but a higher amount of local contaminants compared to options (2) and (3). Therefore, decision makers should consider what impacts are more important for the specific context in which an AD and post-composting plant will be located. In addition, this paper estimates the benefits in terms of energy balance and surface occupancy when a conventional composting plant is converted into an AD and post-composting process.

“…The goal of the zero waste philosophy is to prevent any waste from reaching landfills or incineration plants, since waste transport is also a source of environmental pollution. (Tan et al, 2015;Talaiekhozani et al, 2016;Wang et al, 2016) calculated the reduction in CO 2 emissions resulting from implementation of various waste sorting strategies. According to (Tatàno et al, 2015), the processing/recycling of biological waste at the site of generation is the optimal solution.…”

The process of composting biological waste is a natural process – in which heat is released. Biological wastes generated in typical households in Poland – are mainly kitchen waste (KW) and green waste from home gardens (GGW – if they are owned). From the ecological point of view – the most advantageous method of their management is their utilization in the place of production. The paper presents a proposal for effective management of bio-waste arising by composting – with the simultaneous use of heat for greenhouse heating in autumn. This is to encourage residents to independently compost bio-waste – and increase the level of recycling of waste generated in Poland by 2020. Calculations for greenhouses were made – in accordance with the energy audit methodology. The obtained thermal balance results were compared with the actual temperature prevailing in the greenhouse in autumn. These calculations were the basis for calculating the amount of KW and GGW enabling effective heating of greenhouses in the autumn so that the internal temperature does not drop below 10ºC. It has been calculated that 22 kg of composted bio-waste (KW and GGW) will suffice to heat the greenhouse in October with an area of 18 m2.

Bonus Point System for Refuse Classification and Sustainable Development: A Study in China

Abstract:The rapid growth of household waste not only endangers the environment and people's health, but also limits social and economic development. The effective sorting and recycling of garbage can control this problem. Adopting a semi-quantitative case study method, our researchers investigated the effect of a bonus point system for refuse classification that improves the accuracy of refuse classification and the residents' environment awareness. In the system, residents will receive some gifts after sorting the garbage correctly. We also investigated the attitudes of residents and companies towards this novel system. Our researchers employed various methods to analyze garbage-sorting data, questionnaires completed by residents, and interview records. The results show that use of a bonus point system affects the management of domestic waste by improving the accuracy and enhancing the awareness of garbage sorting. Overall, residents support the system and benefit from it, which increases participation and consciousness of environmental protection. However, continuous publicity and coordination of various policies are required to promote the wide-range implementation and sustainable development of this system.
