[ES] El <> es un molino papelero ubicado fuera del casco urbano en Banyeres de Mariola al lado del río Vinalopó. Pertenece a <>, declarada BIC en 2016. El molino en la actualidad está abandonado y en un estado de conservación precario a pesar de la intervención realizada en el 2002. La vegetación y la falta de cubierta en algunos volúmenes ha acelerado el estado actual del molino, dejando patente la necesidad de una actuación en el conjunto arquitectónico. El objeto del trabajo es sentar los estudios previos del edificio para formar el punto de partida hacia una intervención en el edificio. Para su elaboración se ha realizado una investigación previa acerca de su construcción, evolución histórica y materialidad, además de la realización del levantamiento planimétrico y gráfico., [EN] The <> is a paper mill located outside the town centre in Banyeres de Mariola next to the Vinalopó river. It belongs to <>, declared BIC (Asset of Cultural Interest) in 2016. The mill is currently abandoned and in a precarious state of conservation despite the intervention carried out in 2002. The vegetation and lack of roof in some facilities has accelerated the current state of the mill, making it clear that action is needed in the architectural ensemble. The purpose of the work is to set the previous studies of the building to form the starting point towards an intervention in the building. For its elaboration, a previous research about its construction, historical evolution and materiality has been carried out, as well as the realization of the planimetric and graphic survey.

En el presente artículo se evalúa económicamente la construcción de una nueva planta de cogeneración de energía limpia con biomasa forestal por parte de la empresa Norske Skog Biobío (NSBB). Esto para demostrar que esta central a base de biomasa forestal para generación de electricidad es una opción viable en Chile desde la perspectiva económica y ambiental. Para esta evaluación se propone un enfoque que utiliza la "teoría de opciones reales", basada en la aplicación del Método Binomial con Transformada Logarítmica en seis pasos. Además se comparan los resultados obtenidos con este enfoque con los resultados usando los métodos tradicionales. Se comprueba que para todos los casos de estudio el valor arrojado por el método de opciones reales fue mayor al calculado mediante métodos tradicionales. Se concluye entonces que esta alternativa de inversión resulta rentable. This paper evaluates economically build a new cogeneration plant with clean energy from forest biomass company Norske Skog Bio Bio (NSBB). This is to show that this plant-based forest biomass for electricity generation is a viable option in Chilefrom the economic and environmental perspective. For this evaluation, we propose an approach that uses "real options theory" based on the application of log-transformed binomial method with six steps. Also, comparing the results obtained with this approach, the results using traditional methods. It is found that for all cases studied, the value yielded by the real options method was higher than estimated by traditional methods. It is concluded that this alternative profitable investment.

A further closure of the water circuit in paper mills with a relative high optimization of their water network is limited by the increase of contamination in the water and runnability problems of the paper machine. Therefore, new strategies for saving water must be focussed on the treatment of final effluents of the paper mill, aiming to obtain high quality water that may replace fresh water use in some applications. An appropriate treatment train performed at pilot scale, consisting on a previous clarification stage followed by anaerobic and aerobic treatments, ultrafiltration, and reverse osmosis, made possible producing the highest water quality from the final effluent of the mill. Anaerobic pre-treatment showed very good performance assisting the aerobic stage on removing organics and sulphates, besides it produced enough biogas for being considered as cost-effective. Permeate recovery depended on the silica content of the paper mill effluent, and it was limited to a 50–60%. The reject of the membranes fully met the legislation requirements imposed to effluents arriving to municipal wastewater treatment plants.
